    Before: POOLER, HALL, Circuit Judges, and SWEET, District Judge. 
    
    The Honorable Robert W. Sweet, of the United States District Court for the Southern District of New
    York, sitting by designation.
    Appeal from an order entered in the United States District Court for the Southern
    District of New York (William C. Conner, Judge) certifying a single class of plaintiffs
    alleging claims under both the Securities Act of 1933 and the Securities Exchange Act of
    1934. Because we find that the district court did not abuse its discretion in concluding
    that the requirements of Rule 23 were satisfied with respect to the single class, we
    AFFIRM the order granting certification, but we VACATE that portion of the order
    which includes as members of the class individuals who sold their shares prior to
    February 13, 2002, and REMAND for further proceedings.

    DOUGLAS W. HENKIN, Milbank Tweed Hadley & McCloy LLP, New York, NY
    (James N. Benedict, C. Neil Gray, and Kevin M. Ashby, on the brief) for
    Defendant-Appellant Citigroup Global Markets, Inc.
    SWEET, District Judge:
    Defendants Andres Bande, Larry Bautista, Dr. Lim Lek Suan, Edward
    McCormack, Edward McQuaid, Daniel Petri, and Philip Seskin (the “Individual
    Defendants”) and Citigroup Global Markets Inc. (“Citigroup”) (collectively, the
    “Defendants”) appeal from an order of the United States District Court for the Southern
    District of New York (Conner, J.) certifying the proposed class and appointing Peter T.
    Loftin, Norman H. Hunter and Joseph Coughlin (“Plaintiffs”) to serve as class
    representatives and Milberg Weiss LLP to serve as class counsel.
    This appeal raises issues implicating both the substance of the often
    overlapping requirements of typicality and adequacy laid out in Rule 23(a) of the Federal
    Rules of Civil Procedure and the correct standard of proof to be applied by courts in this
    1
    context. We conclude that while the district court did not abuse its discretion in granting
    certification of a class encompassing members who allege claims under both the
    Securities Act of 1933 (the “‘33 Act”) and the Securities Exchange Act of 1934 (the “‘34
    Act”), it did err in certifying as members of the class those individuals who sold their
    stock prior to the February 13, 2002 close of the class period.
    BACKGROUND
    In February 2000, Flag Telecom Holdings, Ltd. (“Flag” or the
    “Company”), a self-described telecommunications “carriers’ carrier” whose business
    involved the sale of access to its telecommunications network, offered its shares to the
    public in an initial public offering (“IPO”). See In re Flag Telecom Holdings, Ltd. Sec.
    Litig. (“In re Flag”), 
    245 F.R.D. 147
    , 151-52 (S.D.N.Y. 2007). In the prospectus, which
    was incorporated into the registration statement filed with the U.S. Securities and
    Exchange Commission in connection with the IPO, Flag stated that it had obtained $600
    million in bank financing and presales of $750 million to construct the Flag Atlantic-1
    cable system (the “FA-1 system”), a fiber-optic submarine cable connecting Paris and
    London to New York.
    According to Plaintiffs, despite an over-supply of fiber optic capacity in
    the market generally, Defendants made various misstatements and omissions in the
    prospectus and during the two years following the IPO, assuring investors that demand
    for Flag’s cable remained strong. On February 13, 2002, the Company disclosed, inter
    alia, that approximately 14% of the Company’s GAAP revenues for the year ending
    December 31, 2001, were associated with so-called “reciprocal transactions.” Described
    2
    by the lower court as “swaps of telecommunications capacity between competitors,”
    reciprocal sales
    may be entered into for legitimate reasons, i.e. to acquire
    access on networks in a market that a company wishes to
    enter in exchange for capacity that has yet to be sold and is
    not otherwise in use (“dark fiber”) . . . [or] can also be
    utilized by a company seeking to defraud investors or its
    creditors to create the impression that the company is
    selling capacity when it is merely unloading useless dark
    fiber on one of its networks in exchange for useless dark
    fiber on a competitor's network.
    In re Flag Telecom Holdings, Ltd. Sec. Litig., 
    352 F. Supp. 2d 429
    , 461 (S.D.N.Y. 2005).
    Following the announcement, Flag stock dropped 46% from its closing price on February
    12, 2002, to $0.36 per share on February 13, 2002.
    Shortly after, on April 1, 2002, Flag filed its 10-K report for fiscal year
    2001, disclosing that the asset value of its FA-1 system was impaired and that it was
    forced to recognize an impairment charge of $359 million. On April 12, 2002, the
    Company filed its Chapter 11 bankruptcy petition. Before being canceled pursuant to
    Flag’s court-approved Chapter 11 plan in September 2002, the Company’s common stock
    was trading at $0.002 per share, having traded as low as $0.0001 per share during the
    bankruptcy.
    The first of several securities class actions was filed against Defendants in
    connection with these events in April 2002. In October 2002, the Honorable William C.
    Conner consolidated several of the actions and appointed Loftin, who purchased
    approximately 1.7 million shares of Flag common stock between July 17, 2000, and
    September 22, 2000, Lead Plaintiff and Milberg Weiss Bershad Hynes & Lerach LLP
    Lead Counsel. Plaintiffs filed a Consolidated Amended Complaint on March 20, 2003,
    3
    and a Second Consolidated Amended Complaint on December 1, 2003. Judge Conner
    dismissed the Second Consolidated Amended Complaint without prejudice, and a Third
    Consolidated Amended Complaint was filed on April 14, 2004, adding Hunter, who
    purchased 200 shares of Flag stock in the IPO, as a plaintiff.
    Plaintiffs bring the instant action on behalf of those who purchased or
    otherwise acquired Flag common stock between February 11, 2000, and February 13,
    2002 (the “Class Period”) for violations of §§ 11, 12(a)(2), and 15 of the ’33 Act (the
    “‘33 Act Plaintiffs”) and §§ 10(b) and 20(a) of the ‘34 Act and Rule 10b-5 promulgated
    thereunder (the “‘34 Act Plaintiffs”). Plaintiffs allege that as a result of Defendants’
    materially false and misleading statements in the Company’s registration statement, SEC
    filings, and press releases, the value of Flag stock was artificially inflated during the
    Class Period. Specifically, the ‘33 Act Plaintiffs allege that Defendants’ statements in the
    prospectus regarding the FA-1 system and the $750 million in presales were misleading
    in that certain of the presales were entered into to ensure financing and did not accurately
    represent profit or demand. 1 The ‘34 Act Plaintiffs allege that the Individual Defendants
    made false and misleading statements regarding the Company’s profitability, most
    notably by falsely reporting the types of reciprocal sales described above.
    In an Amended Opinion and Order dated January 23, 2006, Judge Conner
    denied Defendants’ motion to dismiss, holding that Defendants had not satisfied their
    burden to establish negative causation with respect to the ‘33 Act Plaintiffs’ claims as
    required by 15 U.S.C. §§ 77k(e) and 77l(b). See In re Flag Telecom Holdings, Ltd. Sec.
    Litig., 
    411 F. Supp. 2d 377
    , 383-84 (S.D.N.Y. 2006). The district court rejected
    1
    Citigroup served as the lead underwriter of the IPO, and the Individual Defendants all served as directors
    or officers of Flag around the time of the IPO.
    4
    Defendants’ argument that since the ‘33 Act Plaintiffs did not learn of the allegedly
    misleading pre-sale until after the November 2003 filing of a complaint in a related state
    court action, 2 at which time Flag common stock had been cancelled and was already
    worthless, none of the decline in the stock’s value could be attributed to those
    misstatements. The court found that Defendants had not “demonstrate[d] that the decline
    was not due, at least in part, to the alleged misrepresentations concerning pre-sales in
    Flag’s Prospectus, which presumably inflated the price level attained in the IPO and
    thereby heightened the loss when the price fell virtually to zero.” 
    Id. at 384
    . With the
    court’s approval, Plaintiffs filed a Fourth Consolidated Amended Complaint on October
    15, 2007.
    In September 2007, the district court granted Plaintiffs’ motion for
    certification pursuant to Fed. R. Civ. P. 23 and appointed Loftin, Hunter, and Coughlin 3
    class representatives and Milberg Weiss LLP class counsel. Judge Conner defined the
    certified class as follows:
    All persons or entities who purchased common stock of
    Flag Telecom Holdings, Ltd. (“Flag” or the “Company”)
    between March 6, 2000 and February 13, 2002, inclusive,
    as well as those who purchased Flag common stock
    pursuant to or traceable to the Company's initial public
    offering between February 11, 2000 and May 10, 2000,
    inclusive (collectively, the “Class Period”), but shall
    exclude: (1) defendants herein, members of each individual
    defendants' immediate family, any entity in which any
    defendant has a controlling interest, and the legal affiliates,
    representatives, heirs, controlling persons, successors and
    2
    The “Rahl Complaint,” filed in the Supreme Court of New York State, New York County, on November
    19, 2003, by the Trustee of the Flag Litigation Trust, asserts various claims for breaches of fiduciary duties
    against several defendants, including several of the Individual Defendants named in this action. See Rahl
    v. Bande, 
    316 B.R. 127
     (S.D.N.Y. 2004).
    3
    Coughlin, who purchased 250 shares in the IPO on February 23, 2000, and 100 shares in the market on
    July 3, 2001, brings claims under both the ‘33 and ‘34 Acts.
    5
    predecessors in interest or assigns of any such extended
    party; (2) Verizon Communications, Inc.; and (3) entities
    that had the right to appoint a director to Flag's Board of
    Directors and proceeded to make such an appointment (or,
    for reasons unique to them, chose not to exercise such
    right), such as Dallah Albaraka Holding Company,
    Telecom Asia Corporation Public Co. Ltd., Marubeni
    Corporation, the Asian Infrastructure Fund and Tyco
    International Ltd.
    In re Flag, 245 F.R.D. at 174. In determining that Plaintiffs had established each of the
    Fed. R. Civ. P. Rule 23(a) and (b)(3) requirements, the lower court rejected several of
    Defendants’ arguments now before us on appeal.
    With respect to the typicality requirement of Rule 23(a)(3), Judge Conner
    concluded that “the typicality requirement is met because plaintiffs . . . like the putative
    class members, will attempt to prove that they purchased Flag common stock during the
    Class Period and were injured by defendants’ false and misleading representations made
    in the Registration Statement and throughout the Class Period in violation of the
    securities laws.” Id. at 159. In so doing, the lower court rejected Defendants’ argument
    that a “fundamental conflict” exists between the ‘33 Act and ‘34 Act Plaintiffs. Id.
    Recognizing that the ‘33 Act Plaintiffs are subject to a “negative causation” affirmative
    defense under 15 U.S.C. §§ 77k(e) and 77l(b), which precludes recovery where
    defendants can show “that the decline in Flag’s stock price was due to something other
    than the alleged misstatements concerning the pre-sales,” while the ‘34 Act Plaintiffs are
    required to prove “loss causation,” or “that the decline in Flag’s stock price was due to,
    inter alia, the failure to appropriately disclose the reciprocal transactions that took place
    after the IPO,” the district court concluded that “the two sets of claims are not
    6
    antagonistic to each other because proof of one does not negate an essential element of
    the other.” Id. at 160.
    Judge Conner also rejected Defendants’ several challenges to the
    adequacy of the class representatives. Of particular relevance to Defendants’ appeal, the
    district court found that the class properly included those purchasers who sold their Flag
    shares before February 13, 2002, the last day of the Class Period and the date on which
    Plaintiffs allege Flag disclosed the truth behind the alleged misstatements to the public.
    According to Judge Conner, Plaintiffs sufficiently demonstrated that the truth regarding
    Flag’s financial condition began leaking into the market prior to February 13, 2002.
    Based on various allegations and an event study submitted by Plaintiffs’ expert, the
    district court held it “conceivable that in-and-out purchasers asserting claims under both
    the ‘33 and ‘34 Act may be able to overcome defendants’ affirmative defense of negative
    causation and prove loss causation, respectively, notwithstanding that the February 13,
    2002 announcement is the most critical corrective disclosure.” Id. at 167.
    On September 19, 2007, Defendants sought leave to appeal the district
    court’s grant of Plaintiffs’ motion for class certification pursuant to Fed. R. Civ. P. 23(f)
    and Fed. R. App. P. 5, which we granted on December 12, 2007.
    DISCUSSION
    In reviewing class certification under Rule 23, we apply an abuse-of-
    discretion standard to both the lower court’s ultimate determination on certification, as
    well as to its rulings that the individual Rule 23 requirements have been met. In re Initial
    Pub. Offerings Sec. Litig. (“In re IPO”), 
    471 F.3d 24
    , 31-32 (2d Cir. 2006). The factual
    7
    findings underlying the ruling are reviewed for clear error, and we review de novo
    whether the correct legal standard was applied. Id. at 40-41. Where, as here, the appeal
    challenges the lower court’s grant of class certification, “we accord the district court
    noticeably more deference than when we review a denial of class certification.” In re
    Salomon Analyst Metromedia Litig., 
    544 F.3d 474
    , 480 (2d Cir. 2008) (citation omitted).
    Rule 23(a) sets out the requirements for class certification:
    (1) the class is so numerous that joinder of all members is
    impracticable; (2) there are questions of law or fact
    common to the class; (3) the claims or defenses of the
    representative parties are typical of the claims or defenses
    of the class; and (4) the representative parties will fairly
    and adequately protect the interests of the class.
    Fed. R. Civ. P. 23(a). We recently set forth the standard of proof governing class
    certification as follows:
    (1) a district judge may certify a class only after making
    determinations that each of the Rule 23 requirements has
    been met; (2) such determinations can be made only if the
    judge resolves factual disputes relevant to each Rule 23
    requirement and finds that whatever underlying facts are
    relevant to a particular Rule 23 requirement have been
    established and is persuaded to rule, based on the relevant
    facts and the applicable legal standard, that the requirement
    is met; (3) the obligation to make such determinations is
    not lessened by overlap between a Rule 23 requirement and
    a merits issue, even a merits issue that is identical with a
    Rule 23 requirement; (4) in making such determinations, a
    district judge should not assess any aspect of the merits
    unrelated to a Rule 23 requirement; . . . .
    In re IPO, 471 F.3d at 41. In a later clarification, we further described “the standard of
    proof applicable to evidence proffered to meet” the requirements of Rule 23 as a
    8
    “preponderance of the evidence.” Teamsters Local 445 Freight Div. Pension Fund v.
    Bombardier Inc., 
    546 F.3d 196
    , 202 (2d Cir. 2008).
    To establish typicality under Rule 23(a)(3), the party seeking certification
    must show that “each class member’s claim arises from the same course of events and
    each class member makes similar legal arguments to prove the defendant’s liability.”
    Robidoux v. Celani, 
    987 F.2d 931
    , 936 (2d Cir. 1993). Adequacy “entails inquiry as to
    whether: 1) plaintiff’s interests are antagonistic to the interest of other members of the
    class and 2) plaintiff’s attorneys are qualified, experienced and able to conduct the
    litigation.” Baffa v. Donaldson, Lufkin & Jenrette Sec. Corp., 
    222 F.3d 52
    , 60 (2d Cir.
    2000). The focus is on uncovering “conflicts of interest between named parties and the
    class they seek to represent.” Amchem Prods., Inc. v. Windsor, 
    521 U.S. 591
    , 625, 
    117 S. Ct. 2231
    , 2250, 
    138 L. Ed. 2d 689
     (1997). In order to defeat a motion for certification,
    however, the conflict “must be fundamental.” In re Visa Check/MasterMoney Antitrust
    Litig. (“In re Visa”), 
    280 F.3d 124
    , 145 (2d Cir. 2001) (internal quotations and citation
    omitted), abrogated in part by In re IPO, 
    471 F.3d 24
    .
    I. Disabling Intra-Class Conflict
    On appeal, Defendants renew their argument that the class suffers from a
    fundamental conflict rendering it uncertifiable because “success for the ‘34 Act plaintiffs
    necessarily precludes recovery by the ‘33 Act plaintiffs and vice-versa.” Citigroup Br. at
    31. We do not find, however, that the district court abused its discretion in concluding
    that the typicality requirement is met in this case despite the conflict described by
    Defendants. Although Judge Conner did not directly address the conflict issue in
    9
    connection with the adequacy requirement, we also find that the court did not abuse its
    discretion in determining that any antagonistic interests with respect to causation do not
    constitute the type of “fundamental” conflict that renders the class uncertifiable. See 
    id.
    It is well-established that plaintiffs alleging claims under Section 10(b) of
    the ‘34 Act must prove loss causation. See 15 U.S.C. § 78u-4(b)(4) (“[T]he plaintiff shall
    have the burden of proving that the act or omission of the defendant alleged to violate this
    chapter caused the loss for which the plaintiff seeks to recover damages.”); Stoneridge
    Inv. Partners, LLC v. Scientific-Atlanta, Inc., 
    128 S. Ct. 761
    , 768 (2008) (describing six
    elements of typical 10(b) claim as “(1) a material misrepresentation or omission by the
    defendant; (2) scienter; (3) a connection between the misrepresentation or omission and
    the purchase or sale of a security; (4) reliance upon the misrepresentation or omission; (5)
    economic loss; and (6) loss causation”). To prove loss causation, a plaintiff must
    demonstrate “that the misstatement or omission concealed something from the market
    that, when disclosed, negatively affected the value of the security.” Lentell v. Merrill
    Lynch & Co., 
    396 F.3d 161
    , 173 (2d Cir. 2005). By contrast, under the ‘33 Act, it is the
    defendant who bears the burden of demonstrating that something other than the
    misstatement at issue caused plaintiff’s loss. See 15 U.S.C. §§ 77k(e), 771(b); Akerman
    v. Oryx Commc’ns, Inc., 
    810 F.2d 336
    , 340-42 (2d Cir. 1987) (describing defendants’
    “heavy burden” of proving negative causation under § 11 of the ‘33 Act).
    As the lower court recognized, we have repeatedly analogized the concept
    of loss causation to proximate cause. See, e.g., Lentell, 
    396 F.3d at 173
     (stating that
    although “the tort analogy is imperfect,” “a misstatement or omission is the ‘proximate
    cause’ of an investment loss if the risk that caused the loss was within the zone of risk
    10
    concealed by the misrepresentations and omissions alleged by a disappointed investor”
    (emphasis in original)); Emergent Capital Inv. Mgmt., LLC v. Stonepath Group, Inc., 
    343 F.3d 189
    , 197 (2d Cir. 2003) (“We have often compared loss causation to the tort law
    concept of proximate cause, meaning that the damages suffered by plaintiff must be a
    foreseeable consequence of any misrepresentation or material omission.” (internal
    quotations and citation omitted)). In relying on this familiar concept, Judge Conner
    found fault with Defendants’ argument which, the court concluded, mistakenly
    “overlooks that the decline in value of Flag stock may have been caused by both the
    alleged fraud relating to the reciprocal transactions and the alleged misstatements relating
    to pre-sales found in the Registration Statement.” In re Flag, 245 F.R.D. at 159-60
    (emphasis in original).
    Defendants take issue with the lower court’s application of proximate
    cause to the facts here, namely, its conclusion that the decline in value of Flag stock “may
    have been caused by either or both of [the] alleged acts of deception.” In re Flag, 245
    F.R.D. at 160. They argue that under the Supreme Court’s holding in Dura
    Pharmaceuticals., Inc. v. Broudo, 
    544 U.S. 336
    , 
    125 S. Ct. 1627
    , 
    161 L. Ed. 2d 577
    (2005), loss causation and negative causation add up to a “zero-sum game,” and that by
    establishing loss causation, the ‘34 Act Plaintiffs will necessarily undermine the ‘33 Act
    Plaintiffs’ ability to rebut Defendants’ negative causation defense. Individual Defendants
    Br. at 20.
    We agree with the lower court that the ‘34 Act Plaintiffs can establish “the
    causal link between the alleged misconduct and the economic harm ultimately suffered
    by the plaintiff,” Emergent Capital Inv. Mgmt., 
    343 F.3d at 197
    , without threatening the
    11
    interests of the ‘33 Act Plaintiffs to such a degree as to render the certified class
    representatives atypical or inadequate. Dura stands for the proposition that in fraud-on-
    the-market cases, “an inflated purchase price will not itself constitute or proximately
    cause the relevant economic loss.” 
    544 U.S. at 342
    , 
    125 S. Ct. 1627
    . Rather, to establish
    loss causation, Dura requires plaintiffs to disaggregate those losses caused by “changed
    economic circumstances, changed investor expectations, new industry-specific or firm-
    specific facts, conditions, or other events,” from disclosures of the truth behind the
    alleged misstatements. 
    Id. at 342-43
    , 
    125 S. Ct. 1627
    ; see Lattanzio v. Deloitte &
    Touche LLP, 
    476 F.3d 147
    , 157-58 (2d Cir. 2007) (finding plaintiffs failed to allege
    sufficient facts to show that defendant’s misstatements were the proximate cause of
    plaintiffs’ losses where non-party’s misstatements could also have caused the loss and
    plaintiffs did not “allege[] facts that would allow a factfinder to ascribe some rough
    proportion of the whole loss to [defendant’s] misstatements”).
    Although Defendants have contended to the contrary, it is not inconsistent
    with Dura to permit both the ‘33 and ‘34 Act Plaintiffs to proceed as a single class in
    establishing that each of the misstatements alleged in the complaint was the proximate
    cause of some portion of Plaintiffs’ losses. Securities class actions involving more than
    one misstatement are far from unusual, and both Plaintiffs and Defendants cite several
    post-Dura examples of district courts granting certification where plaintiffs alleged
    claims under both the ‘33 and ‘34 Acts. See, e.g., In re Vivendi Universal, S.A. Sec.
    Litig., 
    242 F.R.D. 76
     (S.D.N.Y. 2007); In re Initial Pub. Offering Sec. Litig., 
    243 F.R.D. 79
     (S.D.N.Y. 2007); In re Tyco Int’l, Ltd., 
    236 F.R.D. 62
     (D.N.H. 2006). Defendants
    attempt to distinguish these cases from the instant case on the grounds that they “involved
    12
    allegations of misstatements made in a single document or allegations of a series of
    misstatements regarding the same subject,” while the allegations here involve unrelated
    misstatements. Individual Defendants Br. at 24—25 n.19. While the relatedness of the
    alleged misstatements may be relevant to the typicality inquiry generally, see, e.g.,
    Robidoux, 
    987 F.2d at 936-37
    , we fail to see how this distinction implicates Dura.
    Defendants point out that “disaggregation requires that a cause be assigned to each piece
    of a stock price decline and precludes assigning two different causes to the same quantum
    of loss.” Individual Defendants Br. at 22. This is true; however, in every litigation of
    this type, the pool of money available for each individual class member’s recovery is
    limited to the loss that the individual actually incurred. We see nothing in the record
    before us that indicates that in these circumstances, where certain plaintiffs are subject to
    a negative causation affirmative defense, such a requirement precludes the certification of
    a single class.
    In affirming Judge Conner’s order with respect to certification of a single
    class of ‘33 and ‘34 Act Plaintiffs, we do not suggest that the issue described by
    Defendants does not deserve the careful and continued attention of the district court, but
    merely that it does not inevitably lead at the present time to the decertification of the
    class. As the lower court recognized, if Plaintiffs are able to prove loss causation with
    respect to both the ‘33 and ‘34 Act claims, then it will be necessary for a jury “to
    determine the extent of harm caused by each [misstatement], and “it is here that the
    interests of class members could diverge.” In re Flag, 245 F.R.D. at 160. We are
    confident in the lower court’s wisdom and ability to utilize the available case
    management tools to see that all members of the class are protected, including but not
    13
    limited to the authority to alter or amend the class certification order pursuant to Rule
    23(c)(1)(C), to certify subclasses pursuant to Rule 23(c)(5), and the authority under Rule
    23(d) to issue orders ensuring “the fair and efficient conduct of the action.” Advisory
    Committee Note on Subdivision (d); see Marisol A. v. Giuliani, 
    126 F.3d 372
    , 379 (2d
    Cir. 1997) (per curiam) (describing “ample tools” available to district court “to fulfill its
    responsibility” under Rule 23).
    II. In-and-Out Traders
    Defendants next argue that the lower court abused its discretion by
    including as members of the certified class those investors who sold their stock before the
    February 13, 2002 alleged corrective disclosures were made. Class Representative
    Hunter, who purchased 200 shares in the IPO and sold them in November 2001, several
    months before the February 13, 2002 disclosures, is one such purchaser. We consider
    Defendants’ argument with respect to these so-called “in-and-out” traders as implicating
    the court’s authority to define the class, pursuant to Fed. R. Civ. P. 23(c)(1)(B), and the
    typicality and adequacy of representation requirements of Rule 23(a).
    Before addressing whether the lower court erred by certifying in-and-out
    traders in this case, we must first briefly address Plaintiffs’ argument that this issue is not
    properly before us on Defendants’ Rule 23(f) appeal. Rule 23(f) gives this court the
    authority to “permit an appeal from an order granting or denying class-action certification
    under this rule.” Fed. R. Civ. P. 23(f). Plaintiffs contend that Defendants’ argument with
    respect to the in-and-out traders goes solely to loss causation, a merits issue properly
    raised in an appeal of a motion to dismiss or summary judgment order, rather than an
    14
    appeal of an order granting class certification. We do not agree that Defendants’
    arguments with respect to the in-and-out traders in this context can be so cleanly
    separated from class certification as to render the issue outside the scope of our Rule
    23(f) review.
    Given the district court’s careful attention to the issue, the lower court
    clearly considered the in-and-out traders’ ability to prove loss causation as relevant to
    Plaintiffs’ certification motion. See In re Flag, 245 F.R.D. at 165-68. Under In re IPO,
    lower courts have an “obligation” to resolve factual disputes relevant to the Rule 23
    requirements and to determine whether the requirements are met, an obligation “not
    lessened by overlap between a Rule 23 requirement and a merits issue, even a merits
    issue that is identical with a Rule 23 requirement.” 
    471 F.3d at 41
    . To the extent the
    lower court was required to make factual findings or conclusions of law with respect to
    any of the Rule 23 requirements, including the definition of the class, those
    determinations are reviewable here. 4 
    Id. at 42
     (“[W]e decline to follow the dictum in
    Heerwagen [v. Clear Channel Commc’n, 
    435 F.3d 219
     (2d Cir. 2006)], suggesting that a
    district judge may not weigh conflicting evidence and determine the existence of a Rule
    23 requirement just because that requirement is identical to an issue on the merits.”).
    Defendants again rely on Dura to argue that any purchaser who sold his or
    her stock prior to Flag’s February 13, 2002 announcement cannot prove loss causation,
    4
    Defendants also seek review of the district court’s denial of its motion to dismiss the ‘33 Act Plaintiffs’
    claims. See In re Flag Telecom Holdings, Ltd. Sec. Litig., 
    411 F. Supp. 2d 377
    . According to Defendants,
    we are permitted under Rule 23(f) to “address issues that should have resulted in the dismissal of some or
    all claims prior to class certification to the extent that such dismissal would have precluded class
    certification.” Citigroup Br. at 25. We disagree. Defendants’ interpretation of the scope of Rule 23(f),
    even in light of In re IPO, goes too far, and we therefore do not reach the lower court’s motion to dismiss
    on this appeal. See also Regents of the Univ. of Cal. v. Credit Suisse First Boston (USA), Inc., 
    482 F.3d 372
    , 380 (5th Cir. 2007) (acknowledging that although “[t]he fact that an issue is relevant to both class
    certification and the merits . . . does not preclude review of that issue,” “the text of [Rule 23(f)] makes plain
    that the sole order that may be appealed is the class certification”).
    15
    and is, at minimum, subject to unique defenses. Judge Conner concluded that since it
    was “conceivable” that in-and-out traders “may be able” to defeat Defendants’ negative
    causation defense and prove loss causation “notwithstanding that the February 13, 2002
    announcement is the most critical corrective disclosure,” they were properly included in
    the certified class. In re Flag, 245 F.R.D. at 167.
    Defendants argue, and we agree, that the district court’s “conceivable”
    standard of proof does not satisfy the preponderance of the evidence standard set forth in
    In re IPO and its progeny. See Bombardier, 
    546 F.3d at 202
     (“[T]he preponderance of
    the evidence standard applies to evidence proffered to establish Rule 23’s
    requirements.”). While applying a more rigorous standard to the other Rule 23
    requirements, the district court quoted Roth v. Aon, 
    238 F.R.D. 603
    , 607-08 (N.D. Ill.
    2006), in support of the proposition that courts facing a challenge to the inclusion of in-
    and-out traders must only determine whether these traders “could conceivably satisfy the
    requirement of loss causation, and [should] therefore [be] included in the proposed class.”
    In re Flag, 245 F.R.D. at 167 (quotations and citation omitted) (alterations in original).
    While we do not disagree with the premise that it may be “premature for
    courts to attempt to determine whether in-and-out traders have suffered losses at the class
    certification stage of the game,” Roth, 238 F.R.D. at 608, “In re IPO makes clear that
    courts may resolve contested factual issues where necessary to decide on class
    certification, and when a claim cannot succeed as a matter of law, the Court should not
    certify a class on that issue.” McLaughlin v. Am. Tobacco Co., 
    522 F.3d 215
    , 228 (2d
    Cir. 2008) (quotations and citation omitted). To the extent that the district court relied on
    16
    a lesser standard in drawing its conclusion that the in-and-out traders could prove loss
    causation as a matter of law, we find it abused its discretion.
    Plaintiffs urge us to reject the approach taken by the Fifth Circuit Court of
    Appeals in Oscar Private Equity Inv. v. Allegiance Telecom, Inc., 
    487 F.3d 261
     (5th Cir.
    2007), requiring proof of loss causation at the class certification stage, and instead follow
    the courts in this Circuit that have rejected such attempts by defendants to require such
    proof for certification. Compare Oscar Private Equity Inv. v. Allegiance Telecom, Inc.,
    
    487 F.3d 261
    , 269 (5th Cir. 2007) (“We hold hence that loss causation must be
    established at the class certification stage by a preponderance of all admissible
    evidence.”), with Wagner v. Barrick Gold Corp., 
    251 F.R.D. 112
    , 118-19 (S.D.N.Y.
    2008) (concluding that in order to trigger the fraud-on-the-market presumption and
    thereby satisfy the predominance requirement of Rule 23(b)(3), plaintiffs need not prove
    loss causation at the class certification stage); Darquea v. Jarden Corp., 06 Civ. 722
    (CLB), 
    2008 WL 622811
    , at *4 (S.D.N.Y. Mar. 6, 2008) (rejecting Oscar and holding
    that to show predominance, “[p]laintiff[s] in the Second Circuit may benefit from the
    fraud-on-the-market presumption of reliance at the certification stage based solely on a
    showing that they made purchases or sales in an efficient market, and need not show that
    they specifically relied on the allegedly fraudulent conduct, as reliance-an element of a
    10(b) claims-is presumed.”); In re Omnicom Group, Inc. Sec. Litig., No. 02 Civ. 4483
    (RCC), 
    2007 WL 1280640
    , at *8 (S.D.N.Y. Apr. 30, 2007) (rejecting loss causation
    challenge to predominance as “an attempt to litigate class certification on the merits of
    the action”). Each of these cases, however, including Oscar, discusses proof of loss
    causation in the context of the Rule 23(b)(3) predominance requirement, and the cases
    17
    cited from this Circuit represent the position that a plaintiff is entitled to a presumption of
    reliance at the certification stage that does not require the court to make a conclusive
    finding as to loss causation in order to trigger the fraud-on-the-market presumption laid
    out in Basic Inc. v. Levinson, 
    485 U.S. 224
    , 
    108 S. Ct. 978
    , 
    99 L. Ed. 2d 194
     (1988), an
    issue that is not before us here.
    By contrast, whether or not Plaintiffs here have met their burden in
    establishing that the in-and-out traders will be able to show loss causation is relevant to
    Rule 23(a) for reasons that do not implicate either predominance or Basic. Since the
    lower court appointed Hunter, an in-and-out trader, as Class Representative, Judge
    Conner was required to find, by a preponderance of the evidence, that he is both an
    adequate and typical representative of the class and not subject to any “unique defenses
    which threaten to become the focus of the litigation.” Baffa, 
    222 F.3d at 59
    .
    Rather than remand this issue to the district court to consider whether the
    in-and-out traders were properly included in the class, we conclude that Plaintiffs have
    not presented sufficient evidence to demonstrate that the in-and-out traders will even
    “conceivably” be able to prove loss causation as a matter of law, and that they therefore
    should not have been included in the certified class. See McLaughlin, 
    522 F.3d at 228
    .
    In Dura, the Supreme Court rejected the view that an inflated purchase
    price is sufficient to plead loss causation on 10(b) claims. 
    544 U.S. at 340
    , 
    125 S. Ct. 1627
    . In so doing, the Court recognized that while “an initially inflated purchase price
    might mean a later loss . . . that is far from inevitably so.” 
    Id. at 342
    , 
    125 S. Ct. 1627
    (emphasis in original). Indeed, “that lower price may reflect, not the earlier
    misrepresentation, but changed economic circumstances, changed investor expectations,
    18
    new industry-specific or firm-specific facts, conditions, or other events, which taken
    separately or together account for some or all of that lower price.” 
    Id. at 343
    , 
    125 S. Ct. 1627
    .
    The Supreme Court’s holding in Dura did not represent a break from this
    Circuit’s approach to loss causation, but rather reaffirmed the analysis we laid out in
    Lentell, 
    396 F.3d at 173
     (holding that to prove loss causation, a plaintiff must allege “that
    the misstatement or omission concealed something from the market that, when disclosed,
    negatively affected the value of the security”). In Lentell, we described the two
    requirements necessary to establish loss causation: 1) the loss must be foreseeable, and
    2) the loss must have been caused by the materialization of the concealed risk. 
    Id.
     In
    order to satisfy the foreseeability prong, a plaintiff must prove that the risk “was within
    the zone of risk concealed by the misrepresentations and omissions alleged by the
    disappointed investor.” 
    Id.
     (emphasis in original).
    The standards laid out in Dura and Lentell are relevant to the in-and-out
    traders because in order to prove loss causation, any plaintiff who sold their stock prior to
    the February 13, 2002 disclosure must prove that the loss they suffered was both
    foreseeable and caused by the “materialization of the concealed risk.” The leakage
    theory put forth by Plaintiffs, 5 and accepted as “conceivable” by the lower court, is based
    on evidence that “the truth regarding Flag’s financial condition began to leak into the
    market prior to the February 13, 2002 announcement, causing the value of Flag common
    stock to decline.” In re Flag, 245 F.R.D. at 166. In support of this theory, Plaintiffs point
    5
    We do not take issue with the plausibility of Plaintiffs’ “leakage” theory. Indeed, in Lentell, we explicitly
    acknowledged that loss causation can be established by a “corrective disclosure to the market” that
    “reveal[s] . . . the falsity of prior recommendations.” Lentell, 
    396 F.3d at
    175 n.4. And nowhere does
    either Dura or our precedent suggest that such disclosures must come from the Company itself.
    19
    to an “event study” prepared by Plaintiffs’ expert, Dr. Hakala, and several “industry
    events” that occurred prior to the Company’s own February 13, 2002 announcement, that
    they claim sufficiently establish loss causation for the in-and-out traders’ claims. 6 None
    of this evidence, however, satisfies Lentell because Plaintiffs have failed to demonstrate
    that any of the information that “leaked” into the market prior to February 13, 2002,
    revealed the truth with respect to the specific misrepresentations alleged. Lentell, 
    396 F.3d at 175
    .
    According to Plaintiffs, “the truth about demand and profitability began to
    leak into the market as early as February 2001 through ‘industry events’” and “by August
    2001, specific news concerning Flag began to leak into the market and depressed Flag’s
    share price further.” Plaintiffs Br. at 17-18. However, rather than providing evidence of
    corrective disclosures, the industry events cited by Plaintiffs appear in their complaint in
    the context of Defendants’ misleading statements themselves. See Third Consolidated
    Amended Complaint ¶ 113 (“[D]efendant McCormack’s statements about the Company’s
    supposedly ‘enviable’ position were an attempt to inaccurately and misleadingly create
    the impression that FLAG was not in the unenviable position of its competitors, who
    were being adversely affected by the glut of bandwidth supply, falling prices and raising
    costs.”); ¶ 119 (“FLAG’s purpose in providing guidance to analysts to adjust forecasts
    upward was to distinguish itself from its competitors who, at the same time, were
    providing much gloomier guidance concerning the state of the telecom industry and the
    outlook for future results.”); ¶ 172 (“FLAG thus continued to issue false and misleading
    statements about its condition and prospects, even though its competitors were beginning
    6
    According to Plaintiffs’ expert witness, the purpose of the event study was to “assess the reaction of Flag
    Telecom’s share price to relevant news events.” Hakala Decl. ¶ 15.
    20
    to acknowledge the difficulties they were facing.”). Plaintiffs cannot have it both ways.
    They cannot allege that Defendants made certain misstatements, namely, that Flag was
    doing well compared to its competitors, and simultaneously argue that the misstatement
    itself constituted a corrective disclosure, that is, the fact that the other companies were
    not doing well exposed the public to the truth about Flag’s misstatements. See Lentell,
    
    396 F.3d at 173
    . To permit Plaintiffs to do so in this context would “tend to transform a
    private securities action into a partial downside insurance policy.” Dura, 
    544 U.S. at
    347-
    48, 
    125 S. Ct. 1627
    .
    Plaintiffs further fail to connect the decline in the price of Flag stock to
    any corrective disclosures as required by the second prong of Lentell. While the event
    study links the decline in value of Flag common stock to various events, Plaintiffs have
    not presented sufficient evidence on which the lower court could conclude that any of the
    events revealed the truth about the subject of any of Defendants’ alleged misstatements.
    Given that the ‘33 and ‘34 Act Plaintiffs primarily allege misstatements with respect to
    the pre-sale and subsequent reciprocal sales, nothing submitted by Plaintiffs link any
    disclosure prior to February 13, 2002, to either of these alleged misrepresentations.
    Without more, we conclude that Plaintiffs have not put forth sufficient evidence on which
    the in-and-out traders could establish loss causation, and they must therefore be excluded
    from the certified class. Accordingly, Hunter may not serve as class representative.
    III. Remaining Arguments
    21
    Defendants raise additional issues challenging the lower court’s grant of
    certification. Since we find these arguments to have no merit, we address them only
    briefly here.
    In addition to the challenges to the adequacy of the class representatives
    discussed above, Defendants claim that Hunter and Coughlin lack the basic familiarity
    and involvement with the class required under Rule 23(a)(4). 7 See Maywalt v. Parker &
    Parsley Petroleum Co., 
    67 F.3d 1072
    , 1077-78 (2d Cir. 1995) (“[C]lass certification may
    properly be denied where the class representatives ha[ve] so little knowledge of and
    involvement in the class action that they would be unable or unwilling to protect the
    interests of the class against the possibly competing interests of the attorneys.” (internal
    quotations and citation omitted) (alteration in original)). Given our general disfavor of
    “attacks on the adequacy of a class representative based on the representative’s
    ignorance,” Baffa, 
    222 F.3d at 61
    , we do not conclude that the lower court abused its
    discretion in finding that the class representatives “are sufficiently knowledgeable and
    involved to adequately represent the putative class.” In re Flag, 245 F.R.D. at 162.
    Similarly, we reject Defendants’ argument that the district court erred in
    including in the class ‘33 Act Plaintiffs who purchased common stock in the secondary
    market traceable to the Company’s IPO as late as May 10, 2000. 8 Despite Defendants’
    evidence that on March 17, 2000 and March 23, 2000, Flag employees exercised “a
    significant amount of stock options” pursuant to the Company’s Long Term-Incentive
    Plan (“LTIP”), the court concluded that since Defendants had produced no evidence that
    7
    We have already found that Hunter cannot serve as a class representative for reasons unrelated to his
    knowledge and competence. Thus, the remainder of our analysis concerns only Coughlin.
    8
    Neither party disputes “that shares that are bought on the market after unregistered shares have entered the
    market cannot be traced back to the IPO.” In re Flag, 245 F.R.D. at 173.
    22
    LTIP shares were actually sold in the market prior to the May 10, 2000 cut-off, it was
    “inclined to resolve the dispute in favor of plaintiffs.” In re Flag, 245 F.R.D. at 173.
    Because we do not conclude that this factual determination constitutes clear error, we
    affirm this aspect of the certification order.
    Finally, Defendants challenge the fairness of the briefing process below on
    due process grounds. We do not find that the lower court abused its “ample discretion”
    to limit both discovery and the extent of the hearing on Rule 23 requirements, In re IPO,
    
    471 F.3d at 41
    , and we therefore also reject Defendants’ due process challenge to the
    certification order.
    CONCLUSION
    For the reasons stated above, the district court’s order granting class
    certification is affirmed with the exception of that portion of the order that includes in the
    class those individuals who sold their Flag stock prior to February 13, 2002. To the
    extent the certified class includes such individuals, that portion of the order is vacated,
    and the case is remanded to the district court for further proceedings.
