    24   Before:           LIVINGSTON, CARNEY, and SULLIVAN, Circuit Judges.
    25
    26         Michael Gramins, a trader of Residential Mortgage‐Backed Securities
    27   (“RMBS”), was convicted of conspiracy to commit wire fraud and securities fraud
    28   by a jury in the United States District Court for the District of Connecticut. At
    29   Gramins’s trial, the district court had admitted testimony from one of Gramins’s
    30   counterparties tending to establish that the counterparty credited Gramins’s
    31   representations when Gramins acted as a “broker” between two counterparties.
    1   The Clerk of Court is respectfully instructed to amend the caption as set forth
    above.

    1   Shortly following Gramins’s conviction, we decided United States v. Litvak, 889
    
    2 F.3d 56
    (2d Cir. 2018) (“Litvak II”), which held in the context of a similar
    3   prosecution that the erroneous and idiosyncratic viewpoint of a defendant’s
    4   counterparty could not be relevant to the objective, “reasonable investor” standard
    5   for materiality in a securities fraud prosecution. The district court (Chatigny, J.)
    6   then sought to apply our holding in Litvak II to this case, and granted Gramins’s
    7   motion for a new trial on the basis that counterparty testimony had been
    8   improperly admitted against Gramins at trial. We conclude, however, that the
    9   counterparty testimony at Gramins’s trial was not improperly admitted and did
    10   not implicate our holding in Litvak II. Accordingly, the judgment of the district
    11   court is REVERSED and the case is REMANDED to the district court with
    12   instructions to reinstate the conviction.

    24                                          NY, for Michael Gramins.
    25
    26   DEBRA ANN LIVINGSTON, Circuit Judge:
    27         On June 15, 2017, a jury in the United States District Court for the District of
    28   Connecticut convicted Defendant‐Appellee Michael Gramins of conspiracy to
    29   commit wire fraud and securities fraud.            Gramins and his alleged co‐
    30   conspirators, former traders of Residential Mortgage Backed Securities (“RMBS”)
    31   at Nomura Securities International, Inc. (“Nomura”), lied to their counterparties
    2
    1   about contemporaneous price negotiations with other, third‐party counterparties.
    2   Those lies caused Nomura’s counterparties to increase their bids and decrease
    3   their offers when they would not otherwise have done so. The counterparties
    4   believed that they were adjusting their bids or offers in response to bona fide,
    5   contemporaneous negotiations with those other, third‐party counterparties, and
    6   paying Nomura a modest commission to facilitate supposedly “riskless”
    7   transactions with those counterparties.       In reality, Gramins’s false statements
    8   carved out sizable spreads between Nomura’s buying‐counterparties’ bids and its
    9   selling‐counterparties’ offers, allowing Nomura to reap substantial profits
    10   unbeknownst to the counterparty on either side of the transaction.
    11         At Gramins’s trial, the government elicited testimony from several of
    12   Nomura’s counterparties that Gramins’s and his alleged co‐conspirators’ lies were
    13   important   to   their   investment   decisions—in      other   words,   that   those
    14   misrepresentations were “material.”     Shortly after the jury’s guilty verdict, we
    15   held in United States v. Litvak, 
    889 F.3d 56
    (2d Cir. 2018) (“Litvak II”), that the
    16   admission of testimony from a counterparty who erroneously asserts the existence
    17   of an agency relationship between himself and his broker‐dealer unduly
    18   prejudices the jury on the issue of materiality, violating Federal Rules of Evidence
    3
    1   (“FRE”) 401 and 403 and requiring a new trial. Following the issuance of our
    2   decision in Litvak II, Gramins supplemented his pending motion for a new trial,
    3   arguing that one of the government’s witnesses at his trial—Joel Wollman of QVT
    4   Financial—had implied (without explicitly stating) an erroneous belief in the
    5   existence of an agency relationship between himself and Gramins. The district
    6   court (Chatigny, J.) then granted Gramins’s motion for a new trial, citing Litvak II.
    7   We REVERSE the district court’s order and REMAND to the district court with
    8   instructions to reinstate the conviction and proceed to sentencing.
    9                                    BACKGROUND
    10                                            I.
    11         Gramins’s conspiracy capitalized on certain distinctive features of the
    12   market for RMBS.     As noted above, “RMBS” stands for Residential Mortgage‐
    13   Backed Securities.   RMBS are “large and complex aggregations of residential
    14   mortgages and home equity loans.” Litvak 
    II, 889 F.3d at 59
    . Banks typically
    15   create RMBS by packaging together groups of mortgages and issuing bonds
    16   backed by the principal and interest payments of the homeowners who received
    17   the mortgages.    Investors assess the value of RMBS in part by estimating the
    18   probability of repayment or default on the various loans that comprise them.
    4
    1         RMBS are priced in terms of percentage of face value, with the face value of
    2   each RMBS derived from the value of its component mortgages.                 Investors
    3   negotiate RMBS prices in small increments called “ticks,” with one tick equal to
    4   1/32 of a percentage point of the bond’s face value. Thirty‐two ticks therefore
    5   equal one full percentage point of face value, or one penny on every dollar of face
    6   value. So, for instance, if Nomura agreed to buy a RMBS for “65 and 16 ticks,” it
    7   agreed to pay 65.5% of the face value of that bond.2
    8         RMBS are “bought and sold at very high prices” and, as a result, typically
    9   “marketed to large, sophisticated financial institutions” like banks and hedge
    10   funds. Litvak 
    II, 889 F.3d at 60
    . Given the large size and unique features of each
    11   RMBS, the RMBS market lacks an “exchange” of the sort on which traditional
    12   corporate stocks and Treasury bonds trade. Moreover, the price at which a given
    13   RMBS will trade is generally not publicly known.         Consequently, institutional
    14   investors looking to transact in RMBS must “contact registered broker‐dealers . . .
    15   to find interested buyers or sellers,” or transact “directly with [the] broker‐dealers”
    16   from the broker‐dealers’ own accounts. 
    Id. 2 Throughout
    this opinion, we express the prices of various RMBS with hyphens,
    such that a price of 65 and 16 ticks appears as “65‐16.”
    5
    1         Enter Gramins.       Between 2009 and 2013, Gramins traded RMBS at
    2   Nomura, a broker‐dealer registered with the Securities and Exchange
    3   Commission.      Institutional investors frequently reached out to Nomura when
    4   looking to buy or sell a particular security. Gramins and his fellow traders would
    5   respond to expressions of interest from Nomura’s customers by transacting with
    6   the customers from Nomura’s own inventory or by communicating with other
    7   institutional investors in the hopes of finding a counterparty willing to complete
    8   the desired transaction.
    9         More often than not, Nomura took the latter approach.              Brokers like
    10   Gramins would attempt to match a prospective buyer of a particular RMBS with
    11   a prospective seller of that RMBS (and vice versa), reaping a small commission in
    12   return. Industry participants refer to this function alternatively as “facilitating,”
    13   see J.A. 191, 642, 734, “market making,” see J.A. 517, 544, and “riskless trading,” see
    14   J.A. 194, 252.   The last term reflects the fact that, because Nomura “had the
    15   potential buyer and potential seller already matched up at the time of the
    16   transaction,” J.A. 194, it had practically eliminated any of the “market risk”
    17   associated with holding the security on its own books, J.A. 252.
    6
    1         Participants in the RMBS market distinguish among three types of RMBS
    2   transactions.    First, in the “order trade” scenario described above, “a broker‐
    3   dealer communicates [separately] with an interested buyer and seller and, if
    4   successful, effectuates a transaction in which a RMBS is transferred.” Litvak II,
    
    5 889 F.3d at 60
    . In an order trade, “[t]he broker‐dealer owns the bond, but usually
    6   briefly, in consummating the transaction between the two investors.”                   
    Id. 7 Second,
    in a “BWIC” (“Bids Wanted In Competition”) trade, “a putative seller
    8   sends a bid‐list to multiple broker‐dealers,” who then “solicit expressions of
    9   interest and price ranges from potential buyers” and “place[] a bid in the auction
    10   of [that] particular security.” 
    Id. Both of
    these types of trades fall within the
    11   “riskless” category because the broker‐dealer “ha[s] the potential buyer and
    12   potential seller already matched up at the time of the transaction.”            J.A. 194.
    13   Moreover, in both contexts, the broker‐dealer typically obtains compensation for
    14   its “matching” efforts by selling the bond for slightly more than it paid for it.
    15   Industry participants refer to this difference as “commission,” “pay on top,” or
    16   “spread,” J.A. 195, 196, 580, and often negotiate the amount of the difference
    17   explicitly with the broker‐dealer.3
    3   A typical (market‐standard) commission is eight ticks, or 0.25% of a bond’s face
    7
    1            A third type of transaction has different features. In a so‐called “inventory
    2   trade,” an investor “buys a bond already held in a broker‐dealer’s account” at the
    3   time of the parties’ negotiations. Litvak 
    II, 889 F.3d at 60
    . In that context, the
    4   broker‐dealer has incurred market risk by holding the RMBS in its inventory for a
    5   significant period of time prior to the transaction. And in that context, customers
    6   do not pay any additional commission because the broker‐dealer has transacted
    7   directly from its own inventory—presumably, seeking maximum profit or
    8   minimum loss on its earlier investment in the bond—rather than intermediating
    9   between two interested counterparties.
    10            Nevertheless, while industry participants frequently distinguish among
    11   these three types of trades, the same agency law principles apply to all of them.
    12   “An essential feature of all of these trades . . . is that the broker‐dealer acts solely
    13   in its own interest as a principal.”     
    Id. at 61.
      As a matter of accounting, the
    14   broker‐dealer’s profit in any of the three scenarios outlined above is always simply
    15   the difference between the price at which it sold the security and the price at which
    16   it purchased it.      See 
    id. Moreover, while
    some RMBS transactions may be
    17   effectively “riskless” in practice, the broker‐dealer always assumes some risk in the
    value.
    8
    1   transaction, because “an institutional investor can refuse to purchase a bond held
    2   by the broker‐dealer even when the investor caused the broker‐dealer to purchase
    3   it by an expression of interest . . . .” 
    Id. Consequently, “[a]
    broker‐dealer is not
    4   . . . an agent for its counterparties in these trades,” and the final price in any
    5   transaction between broker‐dealer and counterparty “is determined in an arms‐
    6   length negotiation” between the two. 
    Id. 7 II.
    8         Having outlined the relevant features of the RMBS market, we turn now to
    9   Gramins’s conspiracy to manipulate it.         At trial, the government proved its
    10   conspiracy charge against Gramins with the following evidence. First, three of
    11   Gramins’s co‐conspirators—former RMBS traders at Nomura—testified to the
    12   nature of the scheme. Caleb Chao, a former junior analyst at Nomura, explained
    13   that Gramins and others would “misrepresent . . . prices to clients,” for instance
    14   by “tell[ing] the seller that we were seeing a bid that was lower than what the
    15   bidder had actually bid” or “tell[ing] a bidder that we had an offer that was higher
    16   than the offer actually was.”    J.A. 580.     Chao testified that the effect of these
    17   representations “was to get either one side or both sides to lower their offer [to
    18   sell] or increase their bid [to buy],” thereby “increas[ing] the spread or money that
    9
    1   Nomura earned on the trade.”       J.A. 580–81.   Chao testified that Gramins had
    2   taught him to engage in these deceptive tactics and that he had observed Gramins
    3   engaging in them himself.
    4         Frank Dinucci, a former vice president at Nomura, provided similar
    5   testimony. Dinucci explained that he and other Nomura RMBS traders “would
    6   lie about where we were actually buying or selling securities to clients” in order
    7   to “increase the profit for Nomura.”       J.A. 199.   Dinucci testified that these
    8   misrepresentations induced Nomura’s counterparties to adjust their bid or offer
    9   prices because those counterparties “typically only had the information that we
    10   were giving them regarding price” and thus “basically had to take our word when
    11   it came to the actual price on the bond.” J.A. 200. Like Chao, Dinucci testified
    12   that he had originally learned these deceptive tactics from Gramins and that he
    13   had observed Gramins himself engage in them.            Alejandro Feely, a former
    14   associate at Nomura, described the RMBS trading desk’s trading tactics in a similar
    15   manner. Both Dinucci and Feely testified that Nomura’s RMBS traders would
    16   engage in these tactics “on a daily basis.” J.A. 200, J.A. 642.
    17         The government then introduced evidence of several specific RMBS trades
    18   to further demonstrate Gramins’s role in the conspiracy. All of these trades fell
    10
    1   within the first two types of trades described above (order and BWIC trades) rather
    2   than the third (inventory trades).     On January 5, 2010, for instance, Gramins
    3   facilitated an order trade of AHMA 2007‐1A1 (“AHMA”) bonds between Joel
    4   Wollman of QVT Financial and Chris Creed of Goldman Sachs Asset
    5   Management.       Over instant message—a typical means of communication
    6   between broker‐dealers and institutional investors, see J.A. 192, 240, 335, 441—
    7   Gramins raised the subject of the AHMA bonds with Wollman and confirmed that
    8   Wollman owned some amount of them.             Gramins then told Wollman: “guy
    9   looking to add a bit of this . . . wants me to show a few holders a 46 bid.” Gov’t
    10   Ex. 10J. 4   Wollman then offered to sell the AHMA bonds at 47‐16.           Several
    11   minutes later, but before initiating any conversation with Creed, Gramins replied
    12   to Wollman, “ok, can show you a 46‐16 bid on the ahma,” Gov’t Ex. 10J, as if
    13   Creed had increased his bid in response to Wollman’s offer. Wollman responded
    14   to Gramins by lowering his offer price to 47‐08.
    15          Only then did Gramins message Creed, writing: “hey chris . . . have a
    16   matcher for you.”     Gov’t Ex. 10C.    When Creed expressed interest, Gramins
    Exhibits not contained in the Joint Appendix (“J.A.”) are cited by the exhibit
    4
    number used at trial, and may be accessed through the Second Circuit Records Office.
    11
    1   inflated Wollman’s 47‐08 offer price to 49‐00, telling Creed: “being offered 33mm
    2   ahma 07‐1 a1 @ 49‐00.” Gov’t Ex. 10C. Gramins and Creed discussed the bond
    3   for a few minutes. Before receiving any bid from Creed (but after suggesting to
    4   Creed that he bid above 48‐00), Gramins resumed his chat with Wollman, telling
    5   the latter “i have really been pushing this guy on ahma . . . / he says 47‐00 is best
    6   best, otherwise wants me to move onto other holders.” Gov’t Ex. 10J. Wollman
    7   then agreed to sell his bonds at 47‐00.
    8         Gramins then returned to his chat with Creed. When Creed suggested 48‐
    9   12 and 48‐20 as possible bids, Gramins replied: “happy to show what you want,
    10   but honestly dont think this guy is gonna budge,” referring to the fictitious 49‐00
    11   offer he had previously conveyed. Gov’t Ex. 10C. Creed then told Gramins he
    12   would “pay the 49” if necessary, but would prefer to pay less if possible. Gov’t
    13   Ex. 10C.      Minutes later—and without any intervening interactions with
    14   Wollman, who had already agreed to sell at 47‐00—Gramins told Creed: “chris this
    15   guy isn’t moving at all . . . wants to just stick to his guns . . . so is 49‐00 ok?” Gov’t
    12
    1   Ex. 10C. Creed agreed to pay 49‐00. Nomura then purchased the AHMA bonds
    2   for 47‐00 and sold them for 49‐00, taking a 64‐tick commission.
    3         On February 9, 2011, Gramins engaged in similar conduct while brokering
    4   a trade of WAMU 2005‐AR15 A1C3 (“WAMU”) bonds between PK Banks of DW
    5   Investments and Jordan Rieger of Monarch Alternative Capital. Gramins began
    6   by contacting Rieger about the WAMU bonds that Rieger owned.               Gramins
    7   recommended a range in which Rieger might sell the bonds, but then clarified:
    8   “happy to reflect what you like / and i am purely looking to broker.” J.A. 1337.
    9   Rieger offered to sell the bonds at 52‐24. One minute later, Gramins inflated that
    10   offer price in a conversation with Banks, telling the latter, “have an order on [the
    11   WAMU bond] @ 53‐16.” J.A. 1328. Banks bid 51‐16 in response.
    12         Moments later, Gramins misrepresented Banks’s bid back to Rieger, telling
    13   Rieger, “i have 51‐00 bid.” J.A. 1338. Rieger reacted by lowering his initial offer
    14   to 51‐28. One minute later, Gramins lied to Banks, telling him, “have the wamus
    15   down to 53‐00 now.” J.A. 1329. Banks reacted by raising his bid to 52‐00. At
    16   this point, even though Banks’s bid of 52‐00 now exceeded Rieger’s offer of 51‐28,
    17   Gramins continued to simulate an ongoing negotiation to both counterparties.
    18   He misstated Banks’s bid to Rieger, telling the latter “ok . . . i am trying to push
    13
    1   him more but have 51‐16 [from the buyer].”           J.A. 1338.    This time, Rieger
    2   declined to lower his offer and told Gramins to “keep working.”                J.A.1338.
    3   Nevertheless, a few minutes later, Gramins told Banks, “I have 52‐24 now.” J.A.
    4   1330. Banks then raised his offer again. Banks’s ultimatum to Gramins—“best
    5   @ 52‐04 . . . paying you 52‐10 all in,” J.A. 1333—indicated that he understood
    6   Gramins to be making a 6‐tick commission for facilitating the trade.            Several
    7   minutes later, though, Nomura bought the WAMU from Rieger at 51‐20 and sold
    8   it to Banks at 52‐10, taking a 22‐tick commission.
    9         On March 16, 2011, Gramins employed similar practices while soliciting a
    10   bid from Wollman in the context of a BWIC auction of INDX 2005‐AR14 A1B2
    11   (“INDX”) bonds. After Gramins informed Wollman of the BWIC opportunity,
    12   Wollman bid on the bonds, stating that he “would take a shot at 18‐1.” J.A. 1346.
    13   Wollman asked Gramins, “you gonna use?” J.A. 1346. Gramins confirmed that
    14   he would use Wollman’s bid, telling him: “yes using.”             J.A. 1346.    Several
    15   minutes later, Gramins informed Wollman that the bid had been successful.
    16   JA1347.    As the evidence showed, however, Gramins did not in fact use
    14
    1   Wollman’s bid of 18‐01.     Instead, Gramins bid only 17‐17, won the auction
    2   anyway, and purchased the INDX at that price.
    3         Gramins continued deceiving Wollman after the auction had finished.
    4   With respect to the amount of commission to be paid, Wollman asked Gramins if
    5   he could “do something like 18‐5” given the low price of the bond. J.A. 1347.
    6   Based on the 18‐01 price that Wollman thought Nomura had paid, Wollman’s
    7   proposal would have netted Nomura a four‐tick commission. Several minutes
    8   later, though, Gramins pushed back on that proposal, noting that he (Gramins)
    9   would have been “happy to buy [the INDX] at 19,” and asking Wollman, “do you
    10   mind sticking w the qtr pnt?” J.A. 1350. Wollman agreed to Gramins’s request
    11   and paid Nomura 18‐09, which he believed would net Nomura a market‐standard
    12   eight‐tick commission.   But because Nomura had bid only 17‐17 for the bond,
    13   rather than using Wollman’s bid of 18‐01, Gramins reaped a 24‐tick commission
    14   from Wollman’s purchase.
    15         Caleb Chao also testified to an order trade that he and Gramins brokered
    16   jointly on May 1, 2012. Chao testified that he sat to Gramins’s immediate left on
    17   Nomura’s trading desk, and that Gramins instructed him on how and what to
    18   communicate to clients while brokering trades. While Chao instant messaged the
    15
    1   buyer (Aadil Abbas of Hartford Investment Management Company (“HIMCO”)),
    2   Gramins messaged the seller (Gabe Sunshine of Bracebridge Capital). Gramins
    3   began by alerting Sunshine to a potential trade of PPSI 2004‐WWF1 M3 (“PPSI”)
    4   bonds, saying “gonna have a bid for you shortly.” J.A. 1495. One minute later,
    5   Chao engaged Abbas regarding those same bonds and Abbas bid 78‐22.            One
    6   minute after Chao received Abbas’s bid, Gramins messaged Sunshine, “78 bid.”
    7   Sunshine responded by offering to sell all his PPSI bonds at 78‐16.
    8         Even though, at that point, Abbas’s bid (78‐22) exceeded Sunshine’s offer
    9   (78‐16), Nomura did not execute the trade. Instead, a few minutes after Gramins
    10   had received Sunshine’s offer, Chao falsely stated to Abbas, “seller came back to
    11   us with an 80‐16 offer.” J.A. 1498. Abbas raised his bid to 79‐00 in response.
    12   Chao then told Abbas that the seller “usually likes to engage so dont think we
    13   want to move to best level right away,” and offered to “show 78‐24 and see what
    14   comes back.”    J.A. 1499.   Chao testified at trial that the purpose of this false
    15   statement “was to give Mr. Abbas sort of an illusion, a false illusion that, you
    16   know, we were trying to buy the bonds cheaper for him.” J.A. 592. Contrary to
    17   Chao’s statement to Abbas, though, Gramins did not discuss the PPSI’s price with
    18   Sunshine any further. After waiting a few minutes, Chao simply pretended that
    16
    1   Sunshine had lowered his bid again, telling Abbas, “ok, showing 79‐24 offer now
    2   . . . there might be a little wiggle room here.”      J.A. 1499.   This time, Abbas
    3   declined to raise his bid above 79‐00.        Gramins then bought the PPSI from
    4   Sunshine at 78‐16 and Chao sold it to Abbas at 79‐02. Nomura took an 18‐tick
    5   commission on the trade.
    6         Along with the details of these negotiations, the government also
    7   introduced evidence at trial concerning a then‐recent prosecution for similar
    8   trading practices. In late January 2013, the government had indicted Jesse Litvak,
    9   a trader at the global securities broker‐dealer Jefferies & Company (“Jefferies”), for
    10   making misrepresentations in the context of his business activities.       See United
    11   States v. Litvak, 
    808 F.3d 160
    , 166 (2d Cir. 2015) (“Litvak I”). Jefferies was one of
    12   Nomura’s competitors, and Litvak occupied a trading position similar to
    13   Gramins’s.     The Litvak indictment alleged that Litvak had “fraudulently
    14   misrepresented to purchasing counterparties the costs to Jefferies of acquiring
    17
    1   certain RMBS” and “fraudulently misrepresented to selling counterparties the
    2   price at which Jefferies had negotiated to resell certain RMBS.” Id.5
    3          Jonathan Raiff, Nomura’s head of Global Markets for the Americas, testified
    4   at Gramins’s trial concerning the firm’s reaction to the Litvak indictment. Raiff
    5   testified that the Litvak indictment was “something everyone was aware of,” J.A.
    6   268, was “a subject of conversation” in the RMBS industry, and that “lots of people
    7   were discussing it,” J.A. 299. Raiff also testified that in early February 2013, about
    8   a week after the Litvak indictment, Nomura scheduled a compliance training
    9   session for traders and salespeople in its securitized products groups. Gramins
    10   attended that training session. Raiff testified that the training session “was held
    11   specifically to discuss the conduct at issue in the Litvak indictment,” J.A. 301, and
    12   that the “general focus of the session was if you say something, make sure it’s
    13   accurate,” J.A. 300.     The training session also operated as a “refresher” on
    14   principles from Nomura’s compliance manual, J.A. 319, including its prohibitions
    15   on making misrepresentations to clients.            Testimony concerning the Litvak
    16   indictment and Nomura’s reaction to it was offered by the government as proof
    5The indictment formally charged Litvak with eleven counts of securities fraud
    pursuant to 15 U.S.C. §§ 78j(b), 78ff; one count of fraud against the United States pursuant
    to 18 U.S.C. § 1031; and four counts of making false statements pursuant to 18 U.S.C.
    § 1001. Litvak 
    I, 808 F.3d at 166
    .
    18
    1   that the defendants understood the wrongfulness of their deceptive trading
    2   practices.
    3         The government also introduced evidence of one final RMBS trade that took
    4   place after the Litvak indictment and the associated Nomura compliance training
    5   session. On November 22, 2013, Gramins facilitated an order trade of JPMAC
    6   2006‐WMC1 A4 (“JPMAC”) bonds between Wollman and Harrison Choi of The
    7   TCW Group, Inc. Gramins first messaged Choi, who offered to sell the bonds at
    8   80‐00. Minutes later, Gramins lied to Wollman about Choi’s offer, saying: “ok
    9   here’s what i just got / 29+mm A4’s @ 81‐16.” J.A. 1573. That caused Wollman
    10   to raise his bid to “80 flat.”    J.A. 1574. Minutes later, Gramins lied again, this
    11   time to Choi, and over the phone. Gramins told Choi: “[The buyer] wanted to be
    12   78. I said no. I have 78 and three‐quarters.” J.A. 1582. That caused Choi to
    13   lower his offer to “79 and a quarter.” J.A. 1584.
    14         After speaking to Choi, Gramins called Michael Romanelli (“Romanelli”), a
    15   salesperson for Nomura.          Gramins and Romanelli discussed how to phrase
    16   Choi’s latest offer to Wollman and whether Romanelli (instead of Gramins) should
    17   convey it to Wollman over the phone. The two agreed on a phrasing of “80 and
    18   a half to you,” and Romanelli told Gramins, “keep it in chat, because if I call, he’s
    19
    1   gonna get suspicious and start asking me questions.” J.A. 1586, 1587. Minutes
    2   later, Gramins told Wollman, over instant message, “i have beaten [Choi] up as
    3   much as i can / 80‐16 is the best i can get them to you.”       J.A. 1575.   Gramins
    4   confirmed to Wollman that this price factored in a commission from Choi, even
    5   though he and Choi had not discussed any.             Wollman agreed to the price.
    6   Gramins then bought the JPMAC bond from Choi at 79‐08 and sold it to Wollman
    7   at 80‐16, taking a 40‐tick commission on the trade.
    8                                           III.
    9         On September 3, 2015, the government indicted Gramins, along with his
    10   alleged co‐conspirators Ross Shapiro and Tyler Peters (collectively with Gramins,
    11   the “defendants”).     On March 6, 2017, the government filed the operative
    12   indictment. The indictment charged the defendants with two counts of securities
    13   fraud, pursuant to 15 U.S.C. §§ 78j(b), 78ff and 17 C.F.R. § 240.10b‐5; six counts of
    14   wire fraud, pursuant to 18 U.S.C. § 1343; and one count of conspiracy to commit
    15   securities fraud and wire fraud, pursuant to 18 U.S.C. § 371.
    16         Much of the trial focused on whether the defendants’ lies were “material”
    17   to their counterparties’ investment decisions, as required under the securities and
    18   wire fraud statutes. See, e.g., 15 U.S.C. § 78j(b). The government sought to prove
    20
    1   materiality in part with testimony from four of Nomura’s counterparties: Zachary
    2   Harrison of Putnam Investments, Eric Marks of Ellington Capital Management,
    3   Abbas of HIMCO, and Wollman of QVT Financial.                Before the jury, these
    4   counterparties described the BWICs and order trades outlined above, in which
    5   Gramins or one of his associates had lied to them, and explained how those lies
    6   had impacted their investment decisions.
    7         One of these witnesses, Wollman of QVT Financial, gave the testimony that
    8   Gramins now contends was improperly admitted. In that testimony, Wollman
    9   alluded to the distinction between inventory trades and “riskless transactions,”
    10   explaining that he maintained heightened expectations of truthfulness from his
    11   broker‐dealer in the latter context.       For example, early on in his direct
    12   examination, Wollman stated that he “recognize[d] the relationship between me
    13   and the broker‐dealer can vary so . . . I’ll take that into account in what I’m saying
    14   and how I’m processing what I’m being told.” J.A. 681. He then elaborated on
    15   that statement, explaining that in the context of a BWIC auction, “there I’m literally
    16   just submitting a bid, and I expect the broker is just doing what I’m telling them
    21
    1   to do,” while in the context of an inventory trade, “it’s more me on one side and
    2   the dealer on the other side.” J.A. 681.
    3         Later on in his testimony, Wollman testified that he believed Gramins’s
    4   representations during the AHMA trade because he understood that Gramins was
    5   “acting as a broker in this capacity.”     J.A. 688. In other words, in a “riskless”
    6   order or BWIC trade, Wollman explained, “he’s not . . . buying bonds for his
    7   inventory,” but rather “acting on behalf of another counterparty,” or “facilitating
    8   a trade between me and that other counterparty.”              J.A. 688.    Wollman
    9   emphasized that “in that context, I expect that facts that [Gramins] tells me are
    10   truthful.”   J.A. 688.    Later, in another exchange, Wollman explained that
    11   Gramins was “brokering a trade between me and another counterparty” in the
    12   context of the JPMAC transaction. J.A. 705. In other words, he reiterated, the
    13   bonds at issue “aren’t [Gramins’s] bonds, he is—his role in this is to match together
    14   a seller of bonds and a buyer of bonds—two other counterparties, not him—and
    15   he’s facilitating that transaction.” J.A. 705.
    16         Finally, on redirect examination, the government reviewed the three
    17   charged trades—AHMA, INDX, and JPMAC—in which Wollman had engaged
    18   with Gramins. The government attorney asked Wollman whether he thought he
    22
    1   was “sitting across the table from” Nomura in the context of each trade. J.A. 727.
    2   With respect to each trade, Wollman responded in the negative. In the AHMA
    3   trade, he testified, Nomura was “brokering a trade for me,” or “acting as a broker,
    4   a facilitator.”   J.A. 727.   Regarding the INDX BWIC, he testified that the
    5   transaction “was almost more clerical, administrative than . . . anything else.” 
    Id. 6 Regarding
    the JPMAC trade, too, Wollman explained that the transaction “was a
    7   broker trade” with “a seller and a buyer.”        
    Id. Gramins claims
    that these
    8   portions of Wollman’s testimony were irrelevant and unduly prejudicial under
    9   Litvak II.
    10          The government’s rebuttal summation produced two additional items to
    11   which Gramins objected.       The first involved the government’s reference to
    12   transactions not charged in the indictment. Prior to trial, the government had
    13   moved in limine to preclude evidence of “the supposed absence of criminal activity
    14   in [the defendants’] uncharged securities transactions.”      J.A. 73.   The district
    15   court did not rule on this motion, but the parties informally agreed not to reference
    16   any specific uncharged trades at trial.       In his closing argument, however,
    17   Shapiro’s counsel argued that the trades charged in the indictment amounted to
    18   “substantially less than $5 million” over four years, which could not have
    23
    1   significantly affected the defendants’ compensation, and that therefore the
    2   government had produced “zero evidence” of motive. J.A. 869–70. In response,
    3   on rebuttal summation, the government reminded the jury that “these are a
    4   selection of the trades,” and that “we could be here for six months if we bring you
    5   every trade.” J.A. 896; see also 
    id. (“Dinucci told
    you that these tactics would occur
    6   almost daily; and Feely told you that the defendants would engage in these tactics
    7   at every opportunity, which he also estimated would be daily.”).                After
    8   summations, defense counsel asked the district court for a curative instruction
    9   limiting the jury to those trades specifically charged in the indictment, which the
    10   district court gave.
    11         The second issue concerned the government’s summary of the elements of
    12   securities and wire fraud through the rhetorical question, “Did the defendants lie
    13   to take money?” J.A. 895. The government explained that “[h]ow you answer
    14   this question will answer all the other problems that you have with deliberations,”
    15   because if the defendants lied to take people’s money, “that is intent, that is their
    16   intent to defraud people,” and if the defendants repeatedly did so, that “shows
    17   they thought it would work, they thought it was material.” J.A. 895. Defense
    18   counsel objected to that summary of the law.         In response, the district court
    24
    1   augmented its previous instruction on the definition of willfulness, informing the
    2   jury that “the government must prove beyond a reasonable doubt that the
    3   defendant knew that his conduct was wrongful and involved a significant risk of
    4   violating the law.” J.A. 912.
    5         On June 15, 2017, the jury reached its verdict. The jury convicted Gramins
    6   on the conspiracy count, failed to reach a verdict with respect to Gramins on one
    7   count of securities fraud and one count of wire fraud, and acquitted Gramins on
    8   all remaining counts.6 The district court declared a mistrial on the unresolved
    9   counts but otherwise accepted the jury’s partial verdict.
    10                                              IV.
    11         On August 28, 2017, Gramins filed his post‐trial motions. He moved for a
    12   judgment of acquittal pursuant to Federal Rule of Criminal Procedure (“FRCRP”)
    13   29 on the conspiracy count of which the jury had convicted him, and on the two
    14   substantive counts on which the jury had deadlocked.            He also moved, in the
    15   alternative, for a new trial pursuant to FRCRP 33 on his sole count of conviction.
    16   Finally, Gramins renewed his pre‐trial motion to dismiss the indictment under the
    6   The jury acquitted Shapiro on all counts but the conspiracy charge, on which it
    failed to reach a verdict. The jury acquitted Peters on all counts.
    25
    1   Due Process Clause of the Fifth Amendment, arguing that he lacked fair notice at
    2   the time of the indictment that his trading tactics were illegal. The government
    3   opposed all of Gramins’s motions and filed briefing to that effect on October 20,
    4   2017.
    5           On May 3, 2018, before the district court had ruled on Gramins’s post‐trial
    6   motions, the Second Circuit issued its opinion in Litvak II.         The government’s
    7   prosecution of Jesse Litvak had taken several twists and turns since his initial
    8   indictment in 2013. First, a jury in the United States District Court for the District
    9   of Connecticut had convicted Litvak on the ten counts of securities fraud with
    10   which he was originally charged,7 but this Court vacated those convictions on
    11   evidentiary grounds in Litvak I. Litvak 
    I, 808 F.3d at 169
    . At Litvak’s second trial,
    12   the jury convicted him of a single count of securities fraud. Litvak 
    II, 889 F.3d at 13
      59.     Litvak moved for a judgment of acquittal pursuant to FRCRP 29 or,
    14   alternatively, for a new trial pursuant to FRCRP 33. 
    Id. at 64.
    The district court
    15   denied those motions, and Litvak again appealed its ruling to this Court. 
    Id. 7The jury
    had also convicted Litvak on one count of fraud relating to the Troubled
    Asset Relief Program (“TARP”) and four counts of making a false statement in a matter
    within the jurisdiction of the United States government. Litvak 
    I, 808 F.3d at 169
    .
    26
    1         In Litvak II, this Court rejected Litvak’s challenge to the denial of his motion
    2   for a judgment of acquittal, holding that the government’s evidence was sufficient
    3   to support a conviction as a matter of 
    law. 889 F.3d at 66
    –67. But we vacated
    4   Litvak’s conviction and remanded for a new trial anyway, again on evidentiary
    5   grounds.    
    Id. at 72.
      Litvak II held that Litvak’s conviction was tainted by
    6   testimony from Brian Norris, one of Litvak’s counterparties, as to Norris’s
    7   erroneous belief that Litvak had been acting as his agent in executing his trades.
    8   
    Id. at 67.
    The opinion referenced the “reasonable investor” standard that governs
    9   proof of materiality for purposes of securities fraud and reasoned that “Norris’s
    10   indisputably idiosyncratic and unreasonable viewpoint is not . . . probative of the
    11   views of a reasonable, objective investor in the RMBS market.”              
    Id. at 69.
    12   Therefore, this Court held, Norris’s testimony was irrelevant in violation of FRE
    13   401 and likely to confuse or mislead the jury in violation of FRE 403, and the district
    14   court’s admission of that testimony required a new trial. 
    Id. 15 Both
    Gramins and the government filed supplemental briefing with respect
    16   to Gramins’s post‐trial motions in light of our holding and analysis in Litvak II.
    17   On June 5, 2018, the district court ruled on Gramins’s motions. The court denied
    18   Gramins’s motions for a judgment of acquittal, noting that counterparty witnesses
    27
    1   had testified at trial to the importance of Gramins’s misrepresentations and that
    2   “a rational trier of fact could find that the ‘point of view’ of these witnesses was
    3   ‘within the parameters of the thinking of reasonable investors’ in the RMBS market
    4   at the time.” Sp. App. 2 (quoting Litvak 
    II, 889 F.3d at 65
    ). But the district court
    5   granted Gramins’s motion for a new trial.      Although the court acknowledged
    6   that, unlike Norris’s testimony at Litvak’s trial, no witness had explicitly claimed
    7   that an agency relationship existed between Gramins and his counterparties, the
    8   court nevertheless concluded that “Wollman strongly implied that that is how he
    9   viewed the role of broker‐dealers in the RMBS market when brokering trades.”
    10   Sp. App. 14.    Because Wollman’s testimony had suggested to the jury that
    11   Gramins owed fiduciary duties of loyalty and honesty to his trading
    12   counterparties, the district court reasoned, a new trial was necessary.8
    13         The district court also addressed the government’s comments during
    14   rebuttal summation.       The court agreed with defense counsel that the
    15   government’s reference to uncharged transactions was inappropriate, but
    16   concluded that two curative instructions had adequately addressed it. As for the
    8 The district court also rejected Gramins’s renewed motion to dismiss the
    indictment on due process grounds.
    28
    1   government’s rhetorical device asking whether the defendants “l[ied] to take
    2   people’s money,” the district court concluded that “it does not appear that [this]
    3   oversimplification of the law was calculated to inflame the jury,” nor “that the jury
    4   was [in fact] misled.” Sp. App. 12. Accordingly, the district court concluded
    5   that neither statement alone rose to the level of prosecutorial misconduct or
    6   warranted a new trial.    Nevertheless, in granting Gramins’s motion for a new
    7   trial, the district court took those comments into account, reasoning that “[e]ven if
    8   the admission of Wollman’s ‘point of view’ testimony, standing alone, does not
    9   justify vacating Gramins’s conviction, the combination of errors described above
    10   justifies a new trial.” Sp. App. 20.
    11         The government timely appealed the district court’s order granting Gramins
    12   a new trial. The Solicitor General authorized the appeal.
    13                                     DISCUSSION
    14         Our review of the district court’s ruling granting Gramins a new trial
    15   implicates several interlocking legal standards.     Most importantly, this Court
    16   reviews a district court’s decision to grant a new trial pursuant to FRCRP 33 for
    17   “abuse of discretion.” United States v. Robinson, 
    430 F.3d 537
    , 542 (2d Cir. 2005).
    18   In applying that standard, “we are mindful that a judge has not abused her
    29
    1   discretion simply because she has made a different decision than we would have
    2   made in the first instance.” United States v. Ferguson, 
    246 F.3d 129
    , 133 (2d Cir.
    3   2001). Nevertheless, we note that a district court has “abuse[d] its discretion if it
    4   based its ruling on an erroneous view of the law or on a clearly erroneous
    5   assessment of the evidence,” Cooter & Gell v. Hartmarx Corp., 
    496 U.S. 384
    , 405
    6   (1990), or rendered a decision that “cannot be located within the range of
    7   permissible decisions,” Zervos v. Verizon N.Y., Inc., 
    252 F.3d 163
    , 169 (2d Cir. 2001).
    8         Furthermore, we also note that the district court exercised its discretion
    9   subject to the standards governing a FRCRP 33 motion for a new trial. FRCRP 33
    10   states that “the court may . . . grant a new trial if the interest of justice so requires.”
    11   Fed. R. Crim. P. 33. While we have stated that FRCRP 33 gives the district court
    12   “broad discretion” to grant a new trial, 
    Ferguson, 246 F.3d at 133
    , district courts
    13   must exercise that discretion “‘sparingly’ and in ‘the most extraordinary
    14   circumstances,’” 
    id. at 134
    (quoting United States v. Sanchez, 
    969 F.2d 1409
    , 1414 (2d
    15   Cir. 1992)), and only in order to “avert a perceived miscarriage of justice,” 
    id. at 16
      133 (quoting 
    Sanchez, 969 F.2d at 1413
    ). In short, the “ultimate test” for granting
    17   a new trial pursuant to FRCRP 33 is “whether letting a guilty verdict stand would
    18   be a manifest injustice.” 
    Id. at 134
    (emphasis added).
    30
    1         Finally, while the district court granted Gramins a new trial on the basis of
    2   the Wollman testimony that it admitted during his original trial, this Court
    3   typically “review[s] a district court’s evidentiary rulings under a deferential abuse
    4   of discretion standard, and . . . will disturb an evidentiary ruling only where the
    5   decision to admit or exclude evidence was ‘manifestly erroneous.’” United States
    6   v. McGinn, 
    787 F.3d 116
    , 127 (2d Cir. 2015) (quoting United States v. Samet, 
    466 F.3d 7
      251, 254 (2d Cir. 2006)). Even if a decision was “manifestly erroneous,” this Court
    8   will affirm “if the error was harmless.” 
    Id. (citing United
    States v. Miller, 
    626 F.3d 9
      682, 688 (2d Cir. 2010)). Therefore, while we review the district court’s FRCRP 33
    10   ruling for abuse of discretion, we note that the district court’s discretion did not
    11   encompass legal error in its reading of Litvak II and was also determined by the
    12   “manifest injustice” standard required for granting a FRCRP 33 motion and the
    13   strong deference typically afforded to evidentiary rulings made at trial.
    14                                             I.
    15         A conviction for securities fraud pursuant to 15 U.S.C. § 78j(b) requires the
    16   government to prove that, “in connection with the purchase or sale of a security
    17   the defendant, acting with scienter, made a material misrepresentation (or a
    18   material omission if the defendant had a duty to speak) or used a fraudulent
    31
    1   device.” United States v. Vilar, 
    729 F.3d 62
    , 88 (2d Cir. 2013) (internal quotation
    2   marks and citations omitted).9      This appeal, as with Litvak’s, “focuses largely on
    3   the element of materiality.”       Litvak 
    II, 889 F.3d at 64
    .      A misstatement in a
    4   securities transaction is material if there is “a substantial likelihood that a
    5   reasonable investor would find the . . . misrepresentation important in making an
    6   investment decision.” 
    Id. (citing Vilar,
    729 F.3d at 89). A misrepresentation is
    7   important to a reasonable investor, in turn, if there is “a substantial likelihood that
    8   the disclosure of the omitted fact would have been viewed by the reasonable
    9   investor as having significantly altered the ‘total mix’ of information made
    10   available.”    Basic Inc. v. Levinson, 
    485 U.S. 224
    , 231–32 (1988) (quoting TSC
    11   Industries, Inc. v. Northway, Inc., 
    426 U.S. 438
    , 449 (1976)).
    12         The government and defense counsel each advanced competing theories of
    13   materiality at trial. The government, for its part, argued that in a negotiation over
    14   the price of a security, information about the price at which other market
    15   participants are willing to trade that security is necessarily important to the
    9   Gramins’s conviction for conspiracy to commit securities fraud implicated those
    same elements because it required the government to prove that Gramins agreed with
    one or more others to commit the unlawful act of securities fraud. See, e.g., United States
    v. Jones, 
    482 F.3d 60
    , 72 (2d Cir. 2006).
    32
    1   reasonable investor.     See, e.g., J.A. 835 (arguing that materiality is “almost
    2   obvious” because Gramins’s statements concealed the fact that the counterparty
    3   “could have bought” the security at a “cheaper [price] than what [he] eventually
    4   ended up paying”); J.A. 899 (calling it “common sense” that “in this brokered
    5   market where you’re lining up people, what the broker‐dealer says about what the
    6   guy over there is willing to pay is going to affect what you might be willing to sell
    7   at”). The government also pointed to the opaque nature of the RMBS market,
    8   which lacks an exchange, forcing counterparties to rely exclusively on their
    9   broker‐dealers for information about price. See, e.g., J.A. 830 (“When it came to
    10   perhaps the most critical piece of information in a negotiation . . . the only way the
    11   bidder knew what the seller was offering[] was if and when the broker‐dealer
    12   Nomura, the defendants, chose to give that information.”).               Finally, the
    13   government relied on the “norms of the market,” whereby, in the context of BWIC
    14   and order trades, “[b]uy side accounts buy and sell to each other through the
    15   broker‐dealer.”   J.A. 898.   In those trading contexts, the government argued,
    16   reasonable investors credited broker‐dealers’ representations based on “years of
    17   experience” with broker‐dealers accurately relaying bids and offers. J.A. 838.
    33
    1         Defense counsel painted a different picture of the RMBS market,
    2   emphasizing the principal‐to‐principal nature of RMBS transactions as a formal
    3   legal matter. See, e.g., J.A. 872 (“Nomura didn’t have to sell anybody anything
    4   unless they got the price they wanted.”). Because every participant in the RMBS
    5   market transacted solely as a principal, the defense argued, sophisticated
    6   counterparties simply would not have placed any significance on their broker‐
    7   dealers’ statements about price. See, e.g., J.A. 873 (“[E]very ounce of proof in this
    8   case tells you that [the counterparties] were not attaching any significance to
    9   anybody’s words or anybody’s acquisition cost or anybody’s profit, not in this
    10   market . . . .”). And Nomura’s counterparties were indeed sophisticated; defense
    11   counsel emphasized the complex mathematical models and other objective
    12   sources that RMBS traders used to guide their investment decisions. See, e.g., J.A.
    13   874 (“[The counterparties] told you the model was the anchor; they told you the
    14   model was the foundation, it was the base of all decision‐making.”); J.A. 874 (“The
    15   model, the data, the price talk, the color, the independent pricing services, that’s
    16   what goes into the final decisions, not Nomura’s sales chat.”).         Finally, the
    17   defense noted that the counterparty witnesses unanimously testified at trial that
    34
    1   they continued to be “happy with the bond they bought or sold at the price they
    2   bought or sold it.” J.A. 871.
    3         “Determination of materiality under the securities laws is a mixed question
    4   of law and fact that the Supreme Court has identified as especially ‘well suited for
    5   jury determination.’” Litvak 
    I, 808 F.3d at 175
    (quoting United States v. Bilzerian,
    6   
    926 F.2d 1285
    , 1298 (2d Cir. 1991)). Absent violation of the FRE, the government
    7   had the right to advance its theory of materiality that, based on relevant features
    8   of the market for RMBS, a reasonable investor would have relied on the sorts of
    9   misrepresentations that Gramins and his co‐conspirators made in the context of
    10   certain trades.   Likewise, the defense had the right to advance its theory of
    11   materiality that, in a market full of sophisticated investors relying largely on
    12   complex models, no reasonable investor would have credited broker‐dealers’
    13   representations about RMBS prices.        And the jury had the right to accept
    14   whichever theory of materiality it found more persuasive in light of the testimony
    15   and other evidence before it at trial. In short, the question of whether Gramins’s
    16   misrepresentations were material under the reasonable investor standard was for
    17   the jury to decide in light of the opposing theories advanced by the two sides and
    18   the evidence that each side marshalled to support them.
    35
    1          The government sought to support its theory of materiality in part with
    2   direct testimony from several of Nomura’s counterparties.          The government
    3   called four of Nomura’s counterparties to the stand, and all four testified that they
    4   considered the defendants’ lies important to them in the context of the price
    5   negotiations in which they occurred.       For example, the government elicited
    6   testimony from Marks concerning a negotiation in which Nomura had lied to
    7   Marks about the seller’s offer price. The government informed Marks of the true
    8   offer price and asked him, “[W]ould the truth, would that information have been
    9   important information in the course of this negotiation?”         J.A. 743.   Marks
    10   responded, “Yes, it would be important. I would probably negotiate differently.
    11   . . . I would probably try to see if I could buy the bonds at a cheaper price.” J.A.
    12   743.   Harrison answered a similar “importance” question similarly, telling the
    13   jury, “In this kind of negotiation with another end account where Nomura was the
    14   middleman, accurately relaying information back and forth would have been
    15   important, especially this kind of information regarding the price level.” J.A. 351.
    16   Abbas likewise answered the “importance” question: “Yes. All of that is the color
    17   that I’m receiving regarding an ongoing negotiation, so from that angle it’s
    18   important.” J.A. 537. See also J.A. 688 (Wollman testifying similarly).
    36
    1         Both Litvak I and Litvak II establish that this sort of testimony from a broker‐
    2   dealer’s counterparties can constitute sufficient evidence of materiality to support
    3   a conviction for securities fraud. See Litvak 
    I, 808 F.3d at 175
    –76 (“[T]estimony
    4   from several representatives of Litvak’s counterparties that his misrepresentations
    5   were ‘important’ to them in the course of the transactions . . . and that they or their
    6   employers were injured by those misrepresentations . . . . precludes a finding that
    7   no reasonable mind could find Litvak’s statements material.” (citation omitted));
    8   Litvak 
    II, 889 F.3d at 66
    (citing Litvak I and holding that “there was sufficient
    9   evidence for a rational jury to find [Litvak’s] misstatements material beyond a
    10   reasonable doubt” on the basis of testimony from Litvak’s counterparties).          In
    11   other words, a rational jury could have found, on the basis of counterparty
    12   testimony that the defendants’ misrepresentations were important to those
    13   counterparties’ investment decisions, that those misrepresentations were material.
    14   The district court therefore properly applied our holdings in Litvak I and II in
    15   denying Gramins’s motion for judgment of acquittal.
    16         The question before us today is thus not whether the government
    17   introduced evidence sufficient to support the jury’s conviction of Gramins on its
    18   theory of materiality, but whether the presentation of that evidence at trial gave
    37
    1   the government an unfair advantage in pressing that theory to the jury.        We
    2   encountered different manifestations of that same general question in Litvak I and
    3   Litvak II. The Litvak precedents reflect our attempts to referee the debate between
    4   the government and defense counsel over these conflicting theories of materiality
    5   by policing the evidence presented at trial to support them.
    6         In Litvak I, we considered testimony from a business school professor and
    7   expert witness for the defense that “where a manager follows rigorous valuation
    8   procedures, as was the case here, consideration of, or reliance on, statements by
    9   sell‐side salesmen or traders concerning the value of a RMBS or the price at which
    10   the broker‐dealer acquired it or could acquire it, are not relevant to that fund’s
    11   determination with respect to how much to pay for a bond.” Litvak 
    I, 808 F.3d at 12
      182. The district court had excluded that expert testimony on relevance grounds,
    13   but we disagreed.      We described the testimony as “highly probative of
    14   materiality” and “undoubtedly relevant to the jury’s determination” on that
    15   element. 
    Id. at 182–183.
    “With such testimony before it, a jury could reasonably
    16   have found that misrepresentations by a dealer as to the price paid for certain
    17   RMBS would be immaterial to a counterparty that relies not on a ‘market’ price or
    18   the price at which prior trades took place, but instead on its own sophisticated
    38
    1   valuation methods and computer model.”          
    Id. at 183.
      In short, the district
    2   court’s evidentiary ruling unfairly tipped the scales against the defense’s theory of
    3   materiality. We consequently vacated that ruling and remanded for a new trial
    4   in which defense counsel could present its theory to the jury unimpeded, and with
    5   relevant expert testimony to support it.
    6         In Litvak II, we encountered a different problem: misstatements of agency
    7   law by government witnesses that unduly supported the government’s theory of
    8   materiality.   At Litvak’s second trial, one of the government’s counterparty
    9   witnesses had erroneously testified that Litvak was acting as his “agent” (rather
    10   than as a principal) in facilitating RMBS transactions between him and other
    11   counterparties.   In addressing this testimony, we reiterated the importance of
    12   point‐of‐view testimony from a defendant’s counterparties, but held that in order
    13   to be relevant such testimony must fall “within the parameters of the thinking of
    14   reasonable investors in the particular market at issue.” Litvak 
    II, 889 F.3d at 65
    .
    15   We reasoned that a counterparty’s erroneous claim of an agency relationship with
    16   the defendant could unduly prejudice the jury “because it might cause a jury to
    17   ‘construe [Litvak’s misstatements] as having great import to a reasonable investor
    18   if coming from the investor’s agent.’” 
    Id. at 68
    (quoting Litvak 
    I, 808 F.3d at 187
    39
    1   (emphasis and alterations in original)).       In short, we again concluded that an
    2   evidentiary ruling at trial had unfairly tipped the scales in favor of the
    3   government, this time by the admission of evidence that unduly advanced the
    4   government’s theory.     We vacated and remanded for a new trial without the
    5   prejudicial testimony.
    6         Litvak II was decided after the conclusion of Gramins’s trial, and the district
    7   court issued its decision granting Gramins a new trial shortly after Litvak II. In
    8   its decision, the district court attempted to follow our lead from Litvak I and Litvak
    9   II, finding that evidentiary rulings at Gramins’s trial had prejudiced the
    10   materiality debate in favor of the government. Here, however, we conclude for
    11   the reasons stated below that nothing that occurred at Gramins’s trial conferred
    12   an undue advantage on the government in the battle over the issue of materiality.
    13   The debate over whether Gramins’s misrepresentations were material should
    14   therefore have remained where it nearly always belongs: with the jury selected to
    15   determine Gramins’s guilt or innocence.
    16                                            II.
    17         The district court granted Gramins a new trial on the basis of this Court’s
    18   evidentiary holdings in Litvak II.    In that case, as described above, this Court
    40
    1   vacated Litvak’s conviction for securities fraud on the basis of statements from one
    2   of Litvak’s counterparties, Brian Norris, who “testified that he believed [Litvak] to
    3   be his agent, and that broker‐dealers serve as an agent in between buyers and
    4   sellers.”   Litvak 
    II, 889 F.3d at 63
    (internal quotation marks and alterations
    5   omitted).    As both parties acknowledged at Gramins’s trial below, Norris’s
    6   statements were in fact incorrect. Litvak, like Gramins and like any other broker‐
    7   dealer in the RMBS market, transacted at all times as a principal, and never as an
    8   agent for any counterparty.
    9          In Litvak II, we held that Norris’s misstatements of agency law provided two
    10   grounds for vacatur of Litvak’s conviction. First, we held that the district court
    11   should have excluded the evidence as irrelevant under FRE 401, which defines
    12   “relevant” evidence to include evidence having “any tendency to make a fact [of
    13   consequence] more or less probable than it would be without the evidence.” Fed.
    14   R. Evid. 401. We began by noting that the materiality requirement for securities
    15   fraud is an objective one, requiring the government to show “that the disclosure
    16   of the omitted fact would have been viewed by the reasonable investor as having
    17   significantly altered the ‘total mix’ of information made available.”     Basic, 
    485 18 U.S. at 231
    –32 (emphasis added). We then reasoned that a counterparty witness’s
    41
    1   “idiosyncratic and erroneous” belief, Litvak 
    II, 889 F.3d at 59
    , “is not . . . probative
    2   of the views of a reasonable, objective investor in the RMBS market,” 
    id. at 69.
    3   Given that no agency relationship exists between a broker‐dealer and its
    4   counterparties as a matter of law, 
    id., a counterparty
    witness’s contrary testimony
    5   that such an agency relationship did in fact exist would be both erroneous and
    6   idiosyncratic, and therefore irrelevant to materiality under the objective,
    7   “reasonable investor” standard, 
    id. 8 As
    an alternative ground for vacatur, we held that the district court should
    9   have excluded Norris’s testimony under FRE 403 given its tendency to confuse or
    10   mislead the jury. 
    Id. FRE 403
    provides for the exclusion of relevant evidence “if
    11   its probative value is substantially outweighed by a danger of one or more of the
    12   following: unfair prejudice, confusing the issues, misleading the jury, undue
    13   delay, wasting time, or needlessly presenting cumulative evidence.”            Fed. R.
    14   Evid. 403.    We reasoned that Norris’s testimony “had a high probability of
    15   confusing the jury by asking it to consider as relevant the perception of a
    16   counterparty representative that was entirely wrong,” and that it could potentially
    17   “mislead the jury based on the government’s argument that a perceived
    18   relationship of trust showed materiality.” Litvak 
    II, 889 F.3d at 69
    . The district
    42
    1   court thus abused its discretion, we held, by failing to exclude the testimony on
    2   either of two potential evidentiary grounds. 
    Id. 3 A.
    4         Gramins sought a new trial, and the district court granted one, on the basis
    5   of Wollman’s testimony against Gramins and its purported similarity to the Norris
    6   testimony at issue in Litvak II. Wollman’s testimony against Gramins, however,
    7   is a horse of a different color.   To begin with, Wollman’s testimony, unlike
    8   Norris’s, was neither “erroneous” nor “idiosyncratic.”      
    Id. at 59.
      First, the
    9   testimony was not “erroneous” because Wollman made no misstatements of
    10   agency law. Nowhere in the record of Gramins’s trial does Wollman state that
    11   he believed that Gramins was his agent, nor that Gramins owed him fiduciary
    12   duties. In fact, nowhere in the record does Wollman advert to any principles of
    13   agency law at all.
    14         The portions of Wollman’s testimony on which Gramins relies do not
    15   erroneously claim an agency relationship with Gramins. For instance, Gramins’s
    16   brief on appeal emphasizes Wollman’s many references to Gramins’s role as a
    17   “broker” or to his conduct as “brokering.” See, e.g., J.A. 688 (Wollman: Gramins
    18   was “acting as a broker in this capacity”); J.A. 705 (Wollman: Gramins was
    43
    1   “brokering a trade between me and another counterparty”).                 But even
    2   contemporaneous statements from Gramins and other broker‐dealer representatives
    3   make clear that the word “broker” is a common shorthand for the role played by
    4   a broker‐dealer in matching one counterparty with another, rather than a synonym
    5   for the legal role of “agent.” See J.A. 1337 (Gramins to seller: “happy to reflect
    6   what you like . . . and I am purely looking to broker.”); J.A. 221 (Dinucci:
    7   “Brokering trades is when you have a buyer and a seller matched up on a bond,
    8   and you simply play the middleman in that transaction.”).
    9         Other statements drawn from Wollman’s testimony likewise do not contain
    10   erroneous statements of agency law.           These comments merely describe the
    11   business context in which Wollman typically interacted with Gramins, which
    12   involved Gramins communicating price negotiations with another counterparty
    13   in an effort to “facilitate” a transaction between Wollman and that counterparty.
    14   For instance, Wollman’s comment that Gramins was “acting on behalf of another
    15   counterparty,” J.A. 688, merely conveyed that Gramins was communicating bids
    16   and offers from that counterparty, rather than negotiating about a bond that he
    17   (Gramins) already owned.        Likewise, Wollman’s comment that he was not
    18   “sitting across the table” from Gramins in the context of a “broker trade,” J.A. 727,
    44
    1   served to contrast an order trade, in which Gramins proposed to deliver a bond to
    2   (or receive it from) a second counterparty other than Wollman, with an inventory
    3   trade, in which no counterparty other than Wollman existed. Wollman explained
    4   throughout his testimony that he had different expectations of Gramins in the
    5   context of an order or BWIC trade, in which Gramins was (to use Gramins’s own
    6   phrase) “merely looking to broker” a trade between two other counterparties, than
    7   he did in the context of an inventory trade, in which Gramins and Wollman
    8   transacted alone.
    9         Indeed, every portion of Wollman’s testimony to which Gramins refers in
    10   defending the district court’s order similarly served to distinguish the former
    11   business context from the latter. Statements like these do not misstate the law—
    12   nor do they correctly state the law. They simply do not purport to reflect any
    13   legal conclusion at all, instead merely describing (often in industry jargon)
    14   Wollman’s different expectations across the two distinctive business contexts.
    15   Most importantly, statements like these vividly contrast with Norris’s testimony
    16   in Litvak II, which explicitly asserted an incorrect belief about agency law that this
    17   Court recognized to be “entirely wrong.” Litvak 
    II, 889 F.3d at 69
    .
    45
    1         Wollman’s trial testimony was also not “idiosyncratic.”              Quite the
    2   contrary: all three of the government’s other counterparty witnesses testified
    3   similarly as to their expectations of broker‐dealer employees purporting to act in
    4   a “broker” capacity.    Marks testified, regarding order trades, that he “would
    5   consider that to be a riskless transaction for the broker,” J.A. 738, and would expect
    6   that the broker‐dealer “would line up both sides of the trade and . . . execute each
    7   side individually but basically as close to simultaneously as they could,” J.A. 744.
    8   Abbas testified that in the context of any non‐inventory transaction, such as an
    9   order trade, he would expect a broker‐dealer to accurately relay his bid to the seller
    10   and would rely on the broker‐dealer’s representations about the seller’s offers as
    11   “color . . . regarding an ongoing negotiation.”      J.A. 537.   Harrison explained,
    12   regarding order trades, that “[i]n this kind of negotiation with another end account
    13   where Nomura was the middleman, accurately relaying information back and
    14   forth would have been important, especially this kind of information regarding
    15   price level.”   J.A. 351.   In light of this corroborating testimony from other
    16   counterparties, Wollman’s description of his expectations when Gramins acted in
    17   a “broker” capacity were hardly atypical.
    46
    1          Relevance under the FRE is a low threshold, easily satisfied. “Evidence is
    2   relevant if: (a) it has any tendency to make a fact more or less probable than it would
    3   be without the evidence; and (b) the fact is of consequence in determining the
    4   action.” Fed. R. Evid. 401 (emphasis added). “To be relevant, evidence need not
    5   be sufficient by itself to prove a fact in issue, much less to prove it beyond a
    6   reasonable doubt.” United States v. Abu‐Jihaad, 
    630 F.3d 102
    , 132 (2d Cir. 2010); see
    7   also United States v. Certified Envtl. Servs., Inc., 
    753 F.3d 72
    , 90 (2d Cir. 2014) (“[T]he
    8   definition of relevance under [FRE] 401 is very broad.”); United States v. White, 692
    
    9 F.3d 235
    , 246 (2d Cir. 2012) (explaining that FRE 401 prescribes a “very low
    10   standard” (internal quotation marks omitted)). “[U]nless an exception applies,
    11   all ‘relevant evidence is admissible.’” 
    White, 692 F.3d at 246
    (alteration omitted)
    12   (quoting Fed. R. Evid. 402).
    13         Views that are not “erroneous or idiosyncratic” do not implicate Litvak II’s
    14   core theory that “the point of view of an investor who is admitted to be wrong”
    15   could not be “relevant to prove what a reasonable investor, neither confused nor
    16   incorrect, would have deemed 
    important.” 889 F.3d at 69
    (internal quotation
    17   marks and citation omitted). And Wollman’s testimony, for the reasons outlined
    18   above, was neither “erroneous” nor “idiosyncratic.”             
    Id. at 59.
       Wollman’s
    47
    1   testimony therefore did not fall within the specific category of irrelevant testimony
    2   proscribed by Litvak II, and the district court erred in concluding otherwise.
    3   Instead, applying the standards for relevance described above, Wollman’s
    4   testimony—that he credited Gramins’s representations when Gramins acted in a
    5   “broker” capacity, facilitating order and BWIC trades—had some “tendency” to
    6   make it “more probable” that a reasonable RMBS investor would have found
    7   Gramins’s lies significant in the course of his or her deliberations. The testimony
    8   was thus relevant to the jury’s assessment of materiality under FRE 401.
    
    9 Barb. 10
            Nor did Wollman’s testimony advance the government’s theory of
    11   materiality in an impermissible manner. As noted above, FRE 403 provides for
    12   the exclusion of relevant evidence “if its probative value is substantially
    13   outweighed by a danger of one or more of the following: unfair prejudice,
    14   confusing the issues, misleading the jury, undue delay, wasting time, or needlessly
    15   presenting cumulative evidence.”      Fed. R. Evid. 403.    Considered within the
    16   overall context of this trial, Wollman’s statements—none of which claimed that
    17   Gramins had acted as his agent or that Gramins owed him fiduciary duties—could
    18   not plausibly have prejudiced, misled, or confused the jury.
    48
    1         To begin with, Wollman himself, when questioned on cross‐examination
    2   about the RMBS trades he engaged in, unequivocally expressed an accurate
    3   understanding about the formal legal nature of those transactions.               He
    4   acknowledged that in the trades he had described on direct examination, “there’s
    5   two parts of th[e] transaction.” J.A. 714. Wollman agreed with defense counsel
    6   that “Nomura first has to buy the bond from the selling counterparty” and that
    7   Nomura “uses its own capital to do that.” J.A. 714. He also agreed that “once
    8   [Nomura] owns [the bond], it has it—owns it in its inventory for even a little bit of
    9   time or a long time and then it gets entered into a separate transaction where it
    10   sells the bond [to the purchasing counterparty].” 
    Id. Wollman also
    repeatedly
    11   agreed with defense counsel’s description that in both BWIC and order trades,
    12   “there’s two separate transactions,” one in which “Nomura buys the bond from
    13   the seller, owns it, uses its capital,” and a second in which Nomura “then sells it
    14   to its customer . . . in a separate transaction.”      
    Id. In light
    of this cross‐
    15   examination exchange, in which defense counsel painstakingly clarified the legal
    16   structure of Wollman’s RMBS transactions with Wollman’s unhesitating
    17   agreement, it is difficult to see how Wollman’s testimony on direct examination—
    18   none of which claimed an agency relationship with Gramins or, indeed, even
    49
    1   alluded to any propositions of agency law in the first place—could have misled or
    2   confused the jury as to the agency issue.
    3         Furthermore, every legal authority present in the courtroom—prosecutors,
    4   defense counsel, and judge—expressly and repeatedly informed the jury that no
    5   agency relationship existed between Wollman and Gramins.          The government
    6   specifically disclaimed the existence of an agency relationship on summation,
    7   informing the jury, “Nobody’s claiming here that anybody is a fiduciary. The
    8   only person who has mentioned the word ‘fiduciary’ in this trial is the defendants.
    9   We’re not claiming that.”    J.A. 836.   On rebuttal summation, the government
    10   explicitly premised its argument on the absence of an agency relationship, arguing
    11   to the jury, “Just because you’re not someone’s agent, doesn’t mean you get to rip
    12   them off.”    J.A. 898 (emphasis added).        Defense counsel also repeatedly
    13   hammered on the absence of a fiduciary relationship between the defendants and
    14   their counterparties, in multiple instances that the jury could not plausibly have
    15   overlooked or even disbelieved.     See, e.g., J.A. 847 (“Every single trade that is
    16   charged in this case involved an arm’s length principal‐to‐principal transaction.”);
    17   J.A. 848 (“Nomura never acted as an agent or an adviser and they never had a
    18   fiduciary duty.”); J.A. 861 (“So here the Court instructed you that, as a principal,
    50
    1   the defendants owed no duty of loyalty to the counterparties and were acting in
    2   their own self‐interest, not the interest of the counterparties.”); J.A. 874 (“We know
    3   this is a principal‐to‐principal market, you’ve heard it several times, everybody for
    4   themselves.”). In short, the principal‐to‐principal nature of the RMBS market—
    5   as opposed to one involving an agency relationship—was an explicit, frequently
    6   reiterated premise of Gramins’s entire trial.10
    7         And nowhere was that clearer than in the district court’s own instructions
    8   to the jury. Indeed, the court explicitly instructed the jury, on multiple occasions,
    9   that Gramins and his co‐defendants were not agents or fiduciaries for any of their
    10   counterparties in any of the RMBS trades at issue.         At the start, during the
    11   government’s case, the court gave the jury a lengthy explanation of the term
    12   “fiduciary” and the legal concept of fiduciary duties. The court then instructed
    10   In granting Gramins’s motion for a new trial, the district court expressed
    concern that “the Government relied on the mistaken notion that trading RMBS for
    one’s own account and ‘brokering’ a transaction are fundamentally different types of
    transactions.” S.A. 18 & n.5. But context makes clear that the government’s
    statements did nothing to contradict its repeated acknowledgment—and the court’s
    clear instruction—that the RMBS trades at issue occurred in a principal‐to‐principal
    market. Rather, as the district court recognized, the government merely used Wollman’s
    testimony to contrast a situation in which “Nomura bought the bond and they’re just
    hanging out with the bond and then they decide to sell the bond to someone else” and
    an order trade in which a broker negotiates simultaneously with both buyer and seller.
    See 
    id. at 18
    n.5.
    51
    1   the jury that “[t]he government does not claim that the relationship between
    2   Nomura and the counterparties involved in this case . . . was a fiduciary
    3   relationship, nor does the government claim that the individual defendants were
    4   in a fiduciary relationship with the counterparties.” J.A. 326. The district court
    5   then further explained that “both sides agree that Nomura and the counterparties
    6   acted as principals, meaning that in each instance each one acted in its own
    7   interest.” J.A. 326.
    8         The court’s final instruction to the jury, immediately preceding its
    9   deliberations, explicitly reiterated that the defendants were not agents of their
    10   counterparties. The district court explained the difference between an agent and
    11   a principal and then stated, “I instruct you that, as a matter of law, the defendants
    12   were at all times acting as principals on behalf of Nomura and not as the agent of
    13   the counterparties.”    J.A. 828.    The court further explained that “when a
    14   defendant bought an RMBS bond from a counterparty, he was not the agent of that
    15   seller; and when a defendant sold an RMBS bond to a counterparty, he was not the
    16   agent of that buyer.” J.A. 828. Finally, the court explained, “[a]s a principal, the
    17   defendants owed no duty of loyalty to the counterparties and were acting in their
    52
    1   own self‐interest, not the interest of the counterparty.” Id.11 The district court
    2   therefore repeatedly and correctly emphasized to the jury Gramins’s formal status
    3   under the law.
    4          We reject as implausible the notion that the jury may have discarded these
    5   straightforward and comprehensive jury instructions, along with supporting
    6   statements of the law from attorneys on both sides, in favor of the contrary and
    7   erroneous legal conclusion that Gramins acted as an agent for his counterparties
    8   or owed them fiduciary duties arising from his RMBS transactions. See United
    9   States v. Snype, 
    441 F.3d 119
    , 129–30 (2d Cir. 2006) (recognizing a “strong
    10   presumption” that jurors follow the instructions they are given).                 It seems
    11   particularly farfetched that the jury would override jury instructions and
    12   corroborating statements of the law from attorneys based on testimony from a
    13   non‐lawyer like Wollman—testimony that did not even use the words “agent,”
    14   “principal,” or “fiduciary,” much less use them to state any conflicting legal
    11 This final sentence also distinguished the district court’s jury instructions here
    from the sole, cursory instruction given in Litvak II, where the court merely explained the
    difference between agent and principal and advised the jury that “Mr. Litvak was not the
    agent of the buyers or sellers of the RMBS,” J.A. 1248, with no additional clarification that
    Litvak’s status as a principal entailed an absence of fiduciary duties arising from his
    transactions with counterparties.
    53
    1   proposition. In short, given the overall context of Gramins’s trial, we conclude
    2   that Wollman’s testimony did not unduly prejudice, mislead, or confuse the jury
    3   under FRE 403.
    
    4 Cow. 5
            The district court reached a contrary conclusion for two reasons that we will
    6   specifically address here.     First, the district court concluded that Wollman’s
    7   testimony “strongly implied” the existence of an agency relationship between
    8   himself and Gramins.       S.A. 14.    But as described above, the excerpts from
    9   Wollman’s testimony highlighted by the district court merely served to
    10   distinguish between two categories of RMBS trades—one in which the broker‐
    11   dealer purported to match a buying counterparty with a selling counterparty
    12   (order or BWIC trades) and another in which the broker‐dealer purported to deal
    13   directly with a single counterparty (inventory trades). The government had the
    14   right to introduce testimony that RMBS counterparties treat a broker‐dealer’s
    15   representations differently in these two contexts.12     While such testimony does
    12 Reasonable RMBS investors might do so for several reasons. For one thing,
    counterparties pay broker‐dealers a commission in order and BWIC trades, but not in
    inventory trades, reflecting a commonly‐held understanding that broker‐dealers acting
    in the former capacity perform a “matching” service for which they are specifically
    compensated. For another, market participants commonly refer to order and BWIC
    trades as “riskless transactions,” reflecting an understanding that while broker‐dealers
    54
    1   not address the fact that the same legal relationship between broker‐dealer and
    2   counterparty obtains across these various trade contexts, the defense was free to
    3   (and did) emphasize that fact on cross‐examination and on summation.                 The
    4   relative significance of these facts about the RMBS market to the “reasonable
    5   investor” standard by which materiality is determined was for the jury to decide.13
    6         Second, in explaining its expansive construction of Litvak II, the district court
    7   relied on our statement in that opinion that “[t]he government’s concept of
    8   subjective trust as evidence of materiality became a back door for the jury to apply
    9   the heightened expectations of trust that an agency relationship carries.” Litvak
    10   
    II, 889 F.3d at 69
    –70.       But read in context, that statement referred to the
    11   government’s attempt at Litvak’s trial “to cabin the effect of Norris’s testimony”
    acting in this capacity retain some risk as a technical legal matter, they have eliminated
    substantially all risk as a practical matter by arranging to transfer the bond from the
    selling counterparty to the buying counterparty by conducting two transactions in quick
    succession. See supra, pp. 6–8.
    13  We decline to decide whether any testimony that does not explicitly state a
    belief that broker‐dealers in the RMBS market are the agents of their counterparties
    could offend Litvak II under some circumstances. But to the extent that counterparty
    testimony could ever offend Litvak II’s prohibition by implication—rather than by
    directly misstating the law—the implication must be substantially stronger than any
    present on this record. Otherwise, as this case demonstrates, an excessive vigilance for
    any suggestion of a legal misperception in a layperson’s testimony could bar the
    government from introducing relevant and non‐prejudicial testimony necessary to
    advance a theory of materiality that the law permits.
    55
    1   by arguing instead that “[Litvak] created the perception of acting as an agent and
    2   that he aimed to establish a relationship of trust.” 
    Id. (internal quotation
    marks
    3   omitted). In short, we concluded that the government’s “relationship of trust”
    4   argument on summation became a device by which it magnified and emphasized
    5   Norris’s “agency” testimony to the jury—allowing Norris’s erroneous views entry
    6   through the “back door” into the jury’s deliberations. Wollman’s comparatively
    7   innocuous testimony does not raise these “back door” concerns with respect to
    8   Gramins’s trial because it contained no erroneous statement to taint the jury’s
    9   deliberations in the first place.
    10         In light of the foregoing analysis, we conclude that the district court’s
    11   decision to grant Gramins a new trial was based on an overbroad reading of Litvak
    12   II and therefore “cannot be located within the range of permissible decisions.”
    13   
    Zervos, 252 F.3d at 169
    . We sympathize with the district court; this novel form of
    14   prosecution has raised issues of first impression and our two prior precedents on
    15   the subject are at times obscure.14 Nevertheless, we conclude that admission of
    14 We are particularly sympathetic to the district court’s concerns stemming from its
    having modeled an evidentiary ruling on the one at issue in Litvak II. Before trial, the
    district court denied defendants’ motion to exclude evidence that, inter alia, defendants’
    victims perceived defendants to be their agents—thereby permitting the government to
    elicit testimony that victims “were misled to believe that the defendants’ interests were
    aligned with their own and that the defendants were truthfully telling them what was
    56
    1   the Wollman testimony to which Gramins objects did not violate FRE 401 or 403,
    2   much less result in a “manifest injustice” at Gramins’s trial, 
    Ferguson, 246 F.3d at 3
      134. The district court erred in concluding to the contrary.
    4                                              III.
    5         The above analysis shows why the district court’s admission of Wollman’s
    6   testimony at Gramins’s trial did not violate the FRE or otherwise constitute error.
    7   But even if admission of that testimony did constitute error, we conclude that any
    8   such error was harmless. “Even if a [district court’s] decision was ‘manifestly
    9   erroneous,’” and thus surpasses the threshold required to grant a motion for a new
    10   trial, this Court will nonetheless affirm the district court’s decision to admit the
    going on and that they relied on that in consummating the transaction.” J.A. 139.
    The court later clarified that if a witness “wants to say that he thought that the
    defendant was acting as his agent, he could be cross‐examined on that.” J.A. 158. In
    granting Gramins’s motion for a new trial, the district court explained that this
    evidentiary decision “followed the ruling in the Litvak case that formed the basis for the
    Second Circuit’s recent vacatur” in Litvak II. S.A. 15. The district court was
    understandably concerned that it may have erred in permitting the introduction of
    certain point‐of‐view evidence pursuant to a ruling modeled after the one that
    necessitated the vacatur of Litvak’s conviction. But even if it was error for the district
    court to permit the government to seek testimony that witnesses believed Gramins to be
    their agent, neither Wollman nor any of the other witnesses actually testified to that
    effect. Unlike the testimony that concerned us in Litvak II, Wollman’s testimony was
    within “mainstream thinking of investors in that market,” Litvak 
    II, 889 F.3d at 65
    , and
    did not suggest that reasonable investors in the RMBS market might have considered
    Gramins their agent.

    1   evidence “if the error was harmless.” Litvak 
    II, 889 F.3d at 67
    (internal quotation
    2   marks omitted).     In assessing harmlessness, we consider four factors: “(1) the
    3   overall strength of the prosecutor’s case; (2) the prosecutor’s conduct with respect
    4   to the improperly admitted evidence; (3) the importance of the wrongly admitted
    5   testimony; and (4) whether such evidence was cumulative of other properly
    6   admitted evidence.”

    , 95 (2d Cir. 2010)).
    8         We agree with Gramins regarding the first factor: the “overall strength of
    9   the prosecutor’s case.”

    . As we explained in
    11   Part 
    I, supra
    , the materiality question here is inherently difficult, both sides
    12   presented complex and opposing theories of materiality to the jury, and the jury
    13   ultimately decided that question on the basis of several days’ testimony from
    14   which competing inferences could have been drawn.           Accordingly, the first
    15   McGinn factor is at best a wash for the government. Nevertheless, we deem any
    16   error harmless on the basis of the other three factors.
    17         With respect to the second factor, “the prosecutor’s conduct with respect to
    18   the improperly admitted [testimony]” was not inappropriate or otherwise unfair
    58
    1   to Gramins. 
    McGinn, 787 F.3d at 127
    . Quite the contrary. As explained above,
    2   the prosecutors actively took steps to disabuse the jury of any mistaken notion that
    3   Gramins acted in a fiduciary capacity. See, e.g., J.A. 836 (government summation)
    4   (“Nobody’s claiming here than anybody is a fiduciary. The only person who has
    5   mentioned the word ‘fiduciary’ in this trial is the defendants. We’re not claiming
    6   that.”). Even when the defendants themselves used terms like “agent” or “broker”
    7   in describing their role, the prosecutors explicitly disclaimed any associated legal
    8   conclusions when referencing that testimony. See, e.g., J.A. 839 (“[Peters] [t]alks
    9   about trading both in agented roles, his word and not mine, and by taking position
    10   risk. Two different roles they played in the market.” (emphasis added)). The
    11   prosecutors placed no undue reliance on Wollman’s supposedly erroneous
    12   testimony, nor did they actively seek to imbue the jury with the mistaken
    13   impression of the law that that testimony supposedly conveyed.
    14         As to the third factor—the testimony’s “importance,” 
    McGinn, 787 F.3d at 15
      127—the record does not support the conclusion that Wollman’s testimony
    16   supplied the crucial difference resulting in the jury’s sole conviction of Gramins.
    17   Because Wollman’s testimony concerned only trades with Gramins (and not with
    18   any of his co‐defendants), and because only Gramins was ultimately convicted of
    59
    1   any charges, Gramins urges us to draw the inference that Wollman’s supposedly
    2   erroneous testimony differentiated Gramins from the other defendants in the
    3   jury’s eyes.   We question the basis for that inference.    Because materiality is
    4   evaluated by an objective, “reasonable investor” standard, any testimony relevant
    5   to this standard would necessarily affect the case against all three defendants.
    6         Moreover, a much more obvious inference exists to explain the different
    7   results.   Materiality was not the only significant issue at Gramins’s trial; the
    8   parties also hotly contested intent.   See, e.g., J.A. 829 (government summation)
    9   (“So [this] again takes you back to those two questions: Materiality and intent.”).
    10   And on that issue, Gramins was clearly not similarly situated to his co‐defendants.
    11   That is because only one of the trades referenced at trial—the JPMAC trade—
    12   occurred after the Litvak indictment, and that trade involved only Gramins. The
    13   fact that the JPMAC trade postdated the Litvak indictment provided strong
    14   evidence for Gramins’s consciousness of wrongdoing. See, e.g., J.A. 268 (Litvak
    15   indictment was “something everyone was aware of” in the RMBS industry); J.A.
    16   301 (describing a compliance training session, which Gramins attended, “held
    17   specifically to discuss the conduct at issue in the Litvak indictment”).           No
    18   similarly strong mens rea evidence was present for the other defendants, and the
    60
    1   jury could easily have rested its conviction of Gramins (but not the others) on that
    2   basis.
    3            We note, additionally, that this understanding of the verdict finds strong
    4   support in the parties’ closing arguments.            Shapiro’s counsel, for instance,
    5   repeatedly emphasized that Shapiro had not engaged in any deceptive trading
    6   practices subsequent to the Litvak indictment and associated compliance session.
    7   See, e.g., J.A. 868 (“[I]n 2013, there was a compliance session. . . . There’s not a shred,
    8   not a shred, of evidence that [Shapiro] ever used these tactics, ever, after that
    9   session, or at all in 2013, even before the session.”); J.A. 870 (“The only evidence
    10   [on intent] is, as soon as [Shapiro] was told you can’t engage in certain tactics, the
    11   desk stopped doing it, he directed people to stop doing it.”). Not only that, but
    12   Shapiro’s counsel even specifically emphasized that Shapiro had not participated
    13   in the JPMAC trade, effectively pointing the finger toward Gramins by the
    14   contrast.    See J.A. 869 (“And what about that November 2013 trade?                 Well,
    15   [Shapiro] wasn’t even involved in that trade.”).         Even Gramins’s own counsel
    16   could not help but repeatedly emphasize the Litvak indictment as the temporal
    17   dividing line between culpable and non‐culpable conduct. See, e.g., J.A. 880 (“The
    18   bottom line is, until Litvak, nobody realized that what they were doing could be
    61
    1   construed as wrong or criminal.” (emphasis added)); J.A. 880 (“But until Litvak,
    2   they never told anybody, you can say this in a chat but you can’t say that.”
    3   (emphasis added)). This repeated emphasis on a category of evidence unique to
    4   Gramins further supports the inference that mens rea (and not materiality) likely
    5   made the difference in his conviction.
    6         Finally, with respect to the fourth McGinn factor, we conclude that
    7   Wollman’s testimony was indeed “cumulative of other properly admitted
    8   [testimony].” 
    McGinn, 787 F.3d at 127
    . Every counterparty witness testified to
    9   the differences between order (or BWIC) and inventory trades, and all of those
    10   counterparty witnesses corroborated Wollman’s testimony that a reasonable
    11   investor would have different expectations for his broker‐dealer in those two
    12   contexts. See, e.g., J.A. 744 (Marks); J.A. 537 (Abbas); J.A. 351 (Harrison). The
    13   fact that Wollman may have placed additional emphasis on this distinction, or
    14   discussed it at greater length, makes no difference. In light of the above analysis,
    15   and our conclusions on three of the four McGinn factors, we conclude that any
    16   error in the admission of Wollman’s testimony was indeed harmless.
    62
    1                                           IV.
    2         Gramins also moved for a new trial on the basis of two statements from the
    3   government’s rebuttal summation: one referencing RMBS trades not in evidence
    4   and another instructing the jury that “lying to take people’s money” would
    5   constitute fraud. We agree with the district court that neither of these statements
    6   alone requires a new trial. See S.A. 11 (reference to uncharged trades “drew an
    7   immediate objection, which was addressed through two curative instructions”);
    8   S.A. 12 (finding that “it does not appear that [the prosecutor’s] oversimplification
    9   of the law was calculated to inflame the jury,” nor that “the jury was misled”).
    10         The district court, however, also concluded its opinion with a cursory
    11   analysis, contained under the heading “Cumulative Prejudice,” stating as follows:
    12   “Even if the admission of Wollman’s ‘point of view’ testimony, standing alone,
    13   does not justify vacating Gramins’s conviction, the combination of errors
    14   described above justifies a new trial.” S.A. 20. Because we conclude that the
    15   admission of Wollman’s testimony did not constitute error at all, we necessarily
    16   conclude that this case does not present the same “combination of errors” that the
    17   district court believed amounted to “cumulative prejudice.”       Furthermore, we
    18   decline to recognize “manifest injustice” on the basis of two stray comments from
    63
    1   the government’s rebuttal summation, both of which were squarely addressed by
    2   the district court’s instructions to the jury and neither of which would
    3   independently require a new trial. See, e.g., United States v. Lumpkin, 
    192 F.3d 280
    ,
    4   290 (2d Cir. 1999) (finding that “the accumulation of non‐errors does not warrant
    5   a new trial”).   Accordingly, we conclude that the district court’s “cumulative
    6   prejudice” analysis does not provide a valid alternative ground for affirmance.
    7                                     CONCLUSION
    8         For the foregoing reasons, we REVERSE the district court’s order and
    9   REMAND with instructions to reinstate the conviction.
