    WENDLANDT, J.    Unlike the fabled "Prince of Thieves," who
    took from the rich to give to the poor,2 the plaintiff Robinhood
    Financial LLC (Robinhood), is accused by the Secretary of the
    Commonwealth (Secretary) of taking advantage of unsophisticated
    investors to fill its own coffers by dispensing ill-suited
    investment advice to these customers and by encouraging them to
    engage in risky trading practices using its online trading
    platform.    This conduct, the Secretary alleges, violated the
    prohibition of the Massachusetts Uniform Securities Act, G. L.
    c. 110A (MUSA), against "unethical or dishonest conduct or
    practices in the securities, commodities[,] or insurance
    business," G. L. c. 110A, § 204 (a) (2) (G) -- a phrase that the
    Secretary has defined to require broker-dealers that provide
    2   Howard Pyle, The Merry Adventures of Robin Hood (1883).
    3
    investment advice to retail customers to comply with a
    statutorily defined fiduciary duty, see 950 Code Mass. Regs.
    § 12.207(1)(a) (2020) (fiduciary duty rule or rule).     Unlike
    prior standards of care, which differentiated between broker-
    dealers and investment advisers in view of their traditionally
    distinct investment services and offerings, the rule brings the
    fiduciary obligations of broker-dealers in line with those of
    investment advisers, making uniform the duties owed by those
    engaged in the business of providing investment advice
    regardless of label.   The rule, according to the Secretary, was
    needed to protect investors confused by the increasingly blurred
    line between broker-dealers providing investment advice and
    investment advisers.
    This case concerns the question whether, by promulgating
    the fiduciary duty rule, the Secretary overstepped the bounds of
    the authority granted to him under MUSA.   We conclude that he
    did not.   We further conclude that the fiduciary duty rule does
    not override the common-law protections available to investors,
    that MUSA is not an impermissible delegation of legislative
    power, and that the rule is not preempted by the Securities and
    Exchange Commission's (SEC) determination to impose a national
    "best interest" standard of care on broker-dealers, 17 C.F.R.
    4
    § 240.15l-1 (2019) (Regulation Best Interest).3    We therefore
    reverse the judgment entered by a Superior Court judge on the
    pleadings in a civil action challenging the validity of the
    fiduciary duty rule, and we remand the matter for further
    proceedings.
    1.   Background.4   This appeal stems from an administrative
    enforcement proceeding brought by the Secretary against
    Robinhood, alleging that Robinhood violated MUSA by, inter alia,
    engaging in "unethical or dishonest conduct or practices in the
    securities, commodities[,] or insurance business," G. L.
    c. 110A, § 204 (a) (2) (G).    In particular, the Secretary
    alleged that Robinhood provided investment recommendations5 to

    Markets, Inc.; the Chamber of Commerce of the United States of
    America and the Greater Boston Chamber of Commerce; the Cornell

    and Tamar Frankel; the New England Legal Foundation; the North

    Public Investors Advocate Bar Association.
    4 Because the case comes before us on the parties' cross
    motions for judgment on the pleadings, "[w]e recite the facts
    'drawn from the parties' pleadings and the exhibits attached
    thereto,'" Mullins v. Corcoran, 
    488 Mass. 275
    , 276 (2021),
    quoting Merriam v. Demoulas Super Mkts., Inc., 
    464 Mass. 721
    ,
    723 (2013), reserving some facts for later discussion.
    5 The Secretary claimed that Robinhood encouraged "frequent,
    risky, and unsuitable trading" by "[i]nexperienced [i]nvestors,"
    published investment categories like "100 Most Popular" or "Top
    Movers," and implemented "[s]trategies to [e]ncourage and
    [i]ncentivize" customer engagement with its trading platform;
    5
    its Internet-based6 customers without considering whether those
    recommendations were in each customer's best interest; this
    conduct, the Secretary contends, violated Robinhood's fiduciary
    duties of care and loyalty under the fiduciary duty rule.
    Robinhood denies the allegations, maintaining that, as a "self-
    directed" brokerage firm, it does not make investment
    recommendations or provide investment advice.7
    After the Secretary initiated the administrative
    proceeding, Robinhood brought the instant action challenging the
    validity of the fiduciary duty rule.8   On the parties' cross
    motions for judgment on the pleadings, see Mass. R. Civ. P.
    12 (c), 
    365 Mass. 754
     (1974), a Superior Court judge determined
    each such practice, the Secretary alleged, was tantamount to
    making investment recommendations to customers. The
    administrative complaint also alleged that Robinhood "targeted
    young individuals with little or no investment experience;
    lacked adequate infrastructure and, as a result, experienced
    repeated outages and disruptions on its trading platform; . . .
    and failed to follow its own written supervisory procedures when
    approving customers for options trading."
    6 Robinhood provides its services on a mobile application
    and website-based trading platform, which, as of 2021, were two
    of the most common methods for placing trades. See Lin,
    Bumcrot, Mottola, Valdes, & Walsh, FINRA Investor Education
    Foundation, Investors in the United States: The Changing
    Landscape 10 (Dec. 2022).
    7 We address only the purely legal issues presented on
    appeal, which are unaffected by this dispute of material fact.

    that the Secretary acted ultra vires,9 exceeding his authority in
    promulgating the rule.   The Secretary appealed, and we allowed
    Robinhood's unopposed application for direct appellate review.
    2.   Regulatory framework.   A brief review of the regulatory
    framework for investment service providers grounds our analysis
    of Robinhood's legal arguments, which are rooted in the
    traditional differences between the investment services provided
    by broker-dealers and investment advisers, as well as the
    different standards of care that consequently have been
    applicable to each.
    a.   Investment services.    Historically, broker-dealers have
    offered services to facilitate and execute securities
    transactions chosen by their customers, earning commissions on
    these trades.10   At most, they have provided, free of any
    9 "Ultra vires," which is Latin for "beyond the powers
    (of)," describes actions that are "beyond the scope of power
    allowed or granted by . . . law." Black's Law Dictionary 1833
    (11th ed. 2019). "When an agency acts beyond the scope of
    authority conferred to it by statute, its actions are invalid
    and ultra vires." Armstrong v. Secretary of Energy & Envtl.
    Affairs, 
    490 Mass. 243
    , 247 (2022).
    10See G. L. c. 110A, § 401 (c) (defining broker-dealer as
    "any person engaged in the business of effecting transactions in
    securities for the account of others or for his own account").
    See also 15 U.S.C. §§ 77b(a)(12) (defining dealer as person who
    engages "in the business of offering, buying, selling, or
    otherwise dealing or trading in securities issued by another
    person"), 78c(a)(4)(A) (defining broker as person "engaged in
    the business of effecting transactions in securities for the
    account of others").
    7
    additional fee, investment advice that was solely incidental to
    the effected transactions.11
    By contrast, investment advisers traditionally have
    provided ongoing investment advice, often taking the
    responsibility of continuous account management.12   Rather than
    charging a commission for each transaction, investment advisers
    usually charged a periodic fee calculated as a percentage of a
    customer's assets under management.
    As a result of the different investment services offered by
    each, Federal and State law historically have held broker-
    dealers and investment advisers to different standards of care.
    Investment advisers, because of their trusted advisory role,
    generally must comply with the full complement of fiduciary
    duties of "utmost good faith, and full and fair disclosure of
    all material facts," and shoulder an "affirmative obligation to
    11See Investment Advisers Act of 1940, 15 U.S.C. § 80b-
    2(a)(11)(C) (Investment Advisers Act) (excluding broker-dealers
    from definition of investment adviser if their "performance of
    [investment advice] services is solely incidental to the
    conduction of [their] business as a broker or dealer" and if
    they "receive[] no special compensation therefor"); G. L.
    c. 110A, § 401 (m) (1) (F) (excluding registered broker-dealers
    from definition of investment adviser).
    12See G. L. c. 110A, § 401 (m) (defining investment adviser
    as "any person who, for compensation, engages in the business of
    advising others, either directly or through publications or
    writings, as to value of securities or as to the advisability of
    investing in, purchasing, or selling securities"). See also 15
    U.S.C. § 80b-2(a)(11) (same).

    , 194 (1963).   See Investment Advisers
    Act of 1940, 15 U.S.C. § 80b-6 (Investment Advisers Act).
    Broker-dealers, because of their more limited role, have
    been subject to traditional agency principles when executing
    customers' transactions.   See, e.g., Hill v. Bache Halsey Stuart
    Shields Inc., 
    790 F.2d 817
    , 824 (10th Cir. 1986) (broker, as
    customer's agent, generally owed fiduciary duties, but scope of
    duties turned on nature of broker's responsibilities because
    agent is only fiduciary within scope of agency).   In addition,
    where a broker-dealer made a recommendation incidental to
    effecting a transaction, a broker-dealer must "have [had] a
    reasonable basis to believe that a recommended transaction or
    investment strategy involving a security or securities is
    suitable for the customer, based on the information obtained
    through the reasonable diligence of the [broker-dealer] to
    ascertain the customer's investment profile."   Financial

    13As discussed infra, a broker-dealer also is subject to
    common-law obligations of care, the precise contours of which

    Over time, the once-clear dichotomy between the services
    offered by broker-dealers, on the one hand, and investment
    advisers, on the other, has "blurred."     XY Planning Network, LLC
    v. United States Sec. & Exch. Comm'n, 
    963 F.3d 244
    , 247 (2d Cir.
    2020).   Certain broker-dealers expanded the types of services
    and products they offered to retail customers, "often
    provid[ing] advice and mak[ing] recommendations about securities
    transactions and investment strategies."    Id. at 248.14   These
    broker-dealers also changed their marketing; "financial services
    firms began to use a variety of titles to describe their
    personnel, such as 'financial advis[er],' 'financial
    consultant,' and 'advis[er],'" Securities and Exchange
    Commission, Study on Investment Advisers and Broker-Dealers as

    Consumer Protection Act 99 (Jan. 2011), https://www.sec.gov
    vary depending on the relationship between the broker-dealer and
    the client.

    Brokers Should be Fiduciaries,

    , 730 (2012)
    ("The birth of electronic markets and the development of
    electronic trading[, which] automated much of the day-to-day
    enterprise of transaction execution without the use of [broker-
    dealers]," led broker-dealers to enhance their services by
    providing advice, "tilt[ing] the balance of brokers' activity
    away from execution and toward advice"). See also Note,
    Regulation Best Interest and the State-Agency Conflict, 
    120 Colum. L. Rev. 1591
    , 1597-1598 (2020) (detailing history of
    broker-dealers beginning to offer financial planning services in
    1980s and shifting from charging commission on trades to fee-
    based pricing).

    Additionally, some broker-dealers' compensation models
    morphed.   Rather than charging commissions, some broker-dealers
    draw revenue from "payments for order flow" -- "a method of
    transferring some of the trading profits from market making to
    the brokers that route customer orders to specialists for
    execution," Securities & Exchange Commission, Special Study:
    Payment for Order Flow and Internalization in the Options
    Markets (Dec. 2020), https://www.sec.gov/news/studies/ordpay.htm

    ("In addition to describing their financial professionals as
    advis[e]rs and describing their services as advisory in nature,
    sales-based firms also routinely use messaging that is designed
    to foster a relationship of trust and reliance," e.g., "Our
    clients always come first," and "Everything we are, do and hope
    to achieve . . . is driven by a straightforward mission: To
    provide the best financial advice and service to our clients"
    [citations omitted]).
    16Payments for order flow involve "a type of volume
    discount -- in either cash or in-kind services -- by which
    market makers (who actually execute securities transactions)
    reward brokers for having directed business to them." Gilman v.
    BHC Sec., Inc., 
    104 F.3d 1418
    , 1420 (2d Cir. 1997). See Note,
    Why Robinhood is Not a Fiduciary, 39 Yale J. Reg. 1445, 1469
    (2022) (under payment for order flow model, broker-dealer firms
    could be "engaged in the practice of skimming off the top of
    orders and giving users a higher price").
    11
    broker-dealer's revenues are tied to the number of trades its
    customers execute, arguably providing an incentive to prefer
    third parties with the best rebate for the broker-dealer, see
    Gilman v. BHC Sec., Inc., 
    104 F.3d 1418
    , 1423-1424 (2d Cir.
    1997), over those with the best execution price for clients.17
    These industry transformations have made the securities
    markets more readily available to more investors;18 however, the
    changes also have caused consumer confusion and investor harm
    despite the existing suitability standard for broker-dealers,
    see Section 913 study, supra at 93-94.      As a result, Federal and
    State authorities have questioned whether adhering to the
    traditional dichotomy between the standard of care owed to
    customers by broker-dealers and investment advisers continues to
    make sense in this evolving marketplace.     See infra.
    b.   SEC's Regulation Best Interest.    Congress, for example,
    passed the Dodd-Frank Wall Street Reform and Consumer Protection
    Act (Dodd-Frank), 
    Pub. L. No. 111-203, § 913
    , 
    124 Stat. 1376
    ,
    1824-1830 (2010), authorizing the SEC to promulgate a new
    standard of care for broker-dealers suitable to the evolving

    Order Flow? (Aug. 22, 2022), https://www.forbes.com/advisor
    /investing/payment-for-order-flow/ [https://perma.cc/K42K-64EW].
    18According to Robinhood, its business model has "created
    competition in the brokerage industry," increasing consumers'
    access to the investment market and causing other broker-dealers
    to eliminate commissions, a trend called the "Robinhood effect."

    landscape and equal to "the standard of conduct applicable to
    . . . investment adviser[s] under . . . the Investment Advisers
    Act," Dodd-Frank § 913(g)(1), 124 Stat. at 1828.   It asked the
    SEC to consider whether, when providing investment advice to
    retail customers, broker-dealers should be required to "act in
    the best interest of the customer without regard to the
    financial or other interest of the [broker-dealer] providing the
    advice."   Dodd-Frank § 913(g)(2), 124 Stat. at 1828.   Congress
    also directed the SEC to conduct a study (Section 913 study) to
    evaluate "the effectiveness of existing legal or regulatory
    standards of care for [broker-dealers] . . . for providing
    personalized investment advice and recommendations about
    securities to retail customers" and to review "whether there are
    legal or regulatory gaps" in the existing regulatory scheme
    relating to such standards of care.   Dodd-Frank § 913(b), 124
    Stat. at 1824.
    The subsequent study confirmed that retail investors often
    "d[id] not understand the differences between investment
    advisers and broker-dealers or the standards of care applicable
    to broker-dealers and investment advisers"; information gathered
    regarding "investor understanding of the roles, duties[,] and
    obligations of investment advisers and broker-dealers . . .
    reflect[ed] confusion by retail investors regarding the roles,
    titles, and legal obligations of investment advisers and broker-
    13
    dealers."   Section 913 study, supra at v.    In the Section 913
    study's findings, the authors recommended the adoption of a
    "uniform fiduciary standard . . . regardless of the regulatory
    label (broker-dealer or investment adviser) of the professional
    providing the advice [emphasis added]."    Id. at v-viii.
    The SEC stopped short of proposing a uniform standard.
    Instead, it proposed a general obligation on broker-dealers,
    requiring that
    "all broker-dealers . . . when making a recommendation of
    any securities transaction or investment strategy involving
    securities to a retail customer, act in the best interest
    of the retail customer at the time the recommendation is
    made without placing the financial or other interest of the
    broker-dealer . . . ahead of the interest of the retail
    customer" (general obligation).
    Regulation Best Interest, Release No. 34-83062, 
    83 Fed. Reg. 21,574
    , 21,575 (May 9, 2018).
    In July 2019, the SEC adopted the Regulation Best Interest
    notwithstanding the Secretary's concerns that the general
    obligation would fail to protect investors who were confused by
    the differences between investment advisors providing investment
    advice and recommendations and broker-dealers who also gave
    investment advice and recommendations.19     See Regulation Best
    19The Secretary criticized the proposed general obligation
    and urged the SEC instead to adopt a "strong uniform fiduciary
    standard" that would impose on broker-dealers a fiduciary duty
    to customers equal to that of investment advisers. Secretary of
    the Commonwealth, Comment Letter on "Regulation Best Interest"
    14
    Interest, Release No. 34-86031, 
    84 Fed. Reg. 33,318
    , 33,329-
    33,330 (July 29, 2019); 
    17 C.F.R. § 240
    .15l-1 (2019).     The SEC
    explained that the general obligation comprised four component
    parts:   (1) a "[d]isclosure obligation," requiring broker-
    dealers to fully and fairly disclose, in writing, any material
    facts relating to the scope and terms of the relationship with
    the customer, including material conflicts of interest related
    to investment recommendations, prior to or at the time of the
    recommendation; (2) a "[c]are obligation," requiring broker-
    dealers to exercise "reasonable diligence, care, and skill" when
    making a recommendation to a retail customer, including
    developing a "reasonable basis" to believe that a recommendation
    is in the "best interest" of a particular customer; (3) a
    "[c]onflict of interest obligation," requiring that broker-
    dealers have and enforce written policies and procedures
    reasonably designed to identify, mitigate, and disclose
    Proposal, Release No. 34-83062, at 1 (Aug. 7, 2018). "As a
    regulator," the Secretary wrote, he had "seen the grievous harm
    suffered by Main Street investors who mistakenly trusted and
    relied on conflicted investment advice [given by broker-
    dealers]." 
    Id.
     The proposed best interest standard for broker-
    dealers, the Secretary continued, was "for all intents and
    purposes substantially the same as the current suitability
    standard," and, he predicted, it would "foster confusion and
    . . . fail to protect vulnerable investors." Id. at 2. "If the
    Commission [did] not adopt a strong and uniform fiduciary
    standard," the Secretary explained, "Massachusetts [would] be
    forced to adopt its own fiduciary standard to protect [its]
    citizens from conflicted advice by broker-dealers." Id. at 1.
    15
    conflicts of interest, and to prevent conflicts that would cause
    them to make recommendations that place their own interests
    ahead of customers'; and (4) a "[c]ompliance obligation,"
    requiring broker-dealers to adopt and enforce written policies
    and practices "reasonably designed to achieve compliance with"
    the Regulation Best Interest.    
    17 C.F.R. § 240
    .15l-1(a)(2)(i)-
    (iv).
    c.   Fiduciary duty rule.   Responding to the SEC's decision
    not to apply a uniform standard, the Secretary published a
    preliminary solicitation for public comments on a proposed State
    "regulation to apply a fiduciary conduct standard on broker-
    dealers, agents, investment advisers, and investment adviser
    representatives when dealing with their customers and clients."
    See Secretary of the Commonwealth, Securities Division,
    Preliminary Solicitation of Public Comments:   Fiduciary Conduct
    Standard for Broker-Dealers, Agents, Investment Advisers, and
    Investment Adviser Representatives (June 14, 2019) (Preliminary
    Solicitation for Public Comments).    He noted the "severe
    financial harm" investors had experienced despite the prior
    suitability standard, and he criticized the Regulation Best
    Interest for failing to define the key term "best interest," and
    setting "ambiguous requirements for how longstanding conflicts
    in the securities industry must be addressed."

    A uniform fiduciary duty rule was necessary for the
    protection of Massachusetts investors and was in the public
    interest, the Secretary concluded, because investors often
    lacked the "education and background" to navigate the
    disclosures distinguishing between broker-dealers and investment
    advisers.   Preliminary Solicitation for Public Comments, supra.
    He relied on empirical studies demonstrating that some investors
    were "fundamentally confused about the differences between
    broker-dealers and investment advisers" when receiving
    investment advice.   Id.
    In December 2019, the Secretary issued a superseding
    request for comment on a revised draft rule, in which he
    reiterated that the fiduciary duty rule was necessary to protect
    investors because it would ensure that broker-dealers, who were
    increasingly "hold[ing] themselves out as providing[] trusted
    advice" to investors, would be held to the "same fiduciary
    standard as investment advisers when providing advice."
    Secretary of the Commonwealth, Securities Division, Solicitation
    of Comments on Proposed Fiduciary Conduct Standard for Broker-
    Dealers, Agents, Investment Advisers, and Investment Adviser
    Representatives 2 (Dec. 13, 2019) (Solicitation of Comments).
    It would require broker-dealers to "make recommendations and
    provide advice based on what is best for the customer or client,
    without regard to the interests of any other person."     Id. at 5.
    17
    The Secretary also responded to concerns that imposing a
    fiduciary duty on broker-dealers would "effectively restrict
    investor choice and access to products and services by
    increasing the cost of advice."     Solicitation of Comments, supra
    at 3.     He explained that "[w]hen preserving 'choice' means
    preserving the option to choose opaque, poorly understood
    products that are sold via heavily conflicted advice, the
    benefits of such 'choice' are illusory."     Id.   He continued,
    "[t]here is no room for 'you get what you pay for' when it comes
    to the quality and integrity of investment advice."      Id. at 3-4.
    Moreover, he concluded that the fiduciary duty rule would
    "enhance[] the quality of advice in the transactional, episodic
    brokerage model without imposing any new ongoing obligations
    upon those providing it."     Id. at 4.
    In March 2020, the Secretary promulgated the fiduciary duty
    rule.     The rule deems it "unethical or dishonest conduct or
    practices" under G. L. c. 110A, § 204 (a) (2) (G), for a broker-
    dealer to "fail[] to act in accordance with a fiduciary duty to
    a customer[20] when providing investment advice or recommending an
    20   The term "customer" is defined to exclude:
    "(a) [a] bank, savings and loan association, insurance
    company, trust company, or registered investment company;
    (b) [a] broker-dealer registered with a [S]tate securities
    commission . . . ; (c) [a]n investment adviser registered
    with the SEC under the Investment Advisers Act of 1940

    investment strategy, the opening of or transferring of assets to
    any type of account, or the purchase, sale, or exchange of any
    security."   950 Code Mass. Regs. § 12.207(1)(a).21   The rule
    requires broker-dealers that provide investment advice to adhere
    "to duties of utmost care and loyalty to the customer," bringing
    their fiduciary obligations when providing investment advice
    more in line with the standards applicable to investment
    advisors.    950 Code Mass. Regs. § 12.207(2).   The "duty of
    care," the rule explains, requires "a broker-dealer or agent to
    use the care, skill, prudence, and diligence that a person
    acting in a like capacity and familiar with such matters would
    use, taking into consideration all of the relevant facts and
    circumstances."22   950 Code Mass. Regs. § 12.207(2)(a).   The

    office performing like functions); or (d) [a]ny other
    institutional buyer, as defined [by regulation]."
    950 Code Mass. Regs. § 12.207(3).
    21Pursuant to 950 Code Mass. Regs. § 12.204(1)(a)(29),
    violation of 950 Code Mass. Regs. § 12.207 is "grounds for
    imposition of an administrative fine, censure, denial,
    suspension[,] or revocation of a registration, or such other
    appropriate action."
    22To comply with the duty of care, broker-dealers "shall
    make reasonable inquiry," which requires consideration of "[t]he
    risks, costs, and conflicts of interest related to all
    recommendations made and investment advice given"; "[t]he
    customer's investment objectives, risk tolerance, financial
    situation, and needs"; and "[a]ny other relevant information."
    950 Code Mass. Regs. § 12.207(2)(a)(1)-(3).
    19
    "duty of loyalty" requires a broker-dealer or agent to
    (1) "[d]isclose all material conflicts of interest"; (2) "[m]ake
    all reasonably practicable efforts to avoid conflicts of
    interest, eliminate conflicts that cannot reasonably be avoided,
    and mitigate conflicts that cannot reasonably be avoided or
    eliminated"; and (3) "[m]ake recommendations and provide
    investment advice without regard to the financial or any other
    interest of any party other than the customer."      950 Code Mass.
    Regs. § 12.207(2)(b)(1)-(3).    "Disclosing conflicts alone does
    not meet or demonstrate the duty of loyalty."      950 Code Mass.

    b.   Secretary's authority under MUSA.   We turn first to
    Robinhood's contention that issuance of the fiduciary duty rule
    exceeded the Secretary's authority under MUSA because the rule
    upsets the long-standing regulatory framework described supra,
    pursuant to which broker-dealers traditionally were subject to a
    different standard of care from that applicable to investment
    advisers.   Our analysis begins with the recognition that "[d]uly
    promulgated regulations of an administrative agency are
    presumptively valid and 'must be accorded all the deference due
    to a statute.'"   Craft Beer Guild, LLC v. Alcoholic Beverages
    Control Comm'n, 
    481 Mass. 506
    , 520 (2019), quoting Pepin v.
    Division of Fisheries & Wildlife, 
    467 Mass. 210
    , 221 (2014).
    Accordingly, "[t]he burden of demonstrating invalidity rests
    squarely on the party challenging the regulation."   Craft Beer

    Adopted in 1972, MUSA was designed to protect investors by
    regulating securities offerings in the Commonwealth.   Bulldog
    Investors Gen. Partnership v. Secretary of the Commonwealth, 
    460 Mass. 647
    , 652, 655 (2011), cert. denied, 
    566 U.S. 987
     (2012)
    (MUSA "largely tracks" Federal Securities Act of 1933, purpose
    of which was "to protect investors").   MUSA broadly authorizes
    the Secretary to administer the law, giving him extensive
    21
    investigative and enforcement powers.   See G. L. c. 110A,
    §§ 406 (a), 407-408.23   MUSA permits the Secretary to make rules
    that "are necessary to carry out the provisions of [MUSA],"
    including rules that "defin[e] any terms, whether or not used in
    [MUSA], insofar as the definitions are not inconsistent with the
    provisions of [MUSA]."   G. L. c. 110A, § 412 (a).   The
    authorization permits the Secretary discretion to establish
    regulations "necessary or appropriate in the public interest or
    for the protection of investors and consistent with the purposes
    fairly intended by the policy and provisions of [MUSA]."     G. L.
    c. 110A, § 412 (b).   See, e.g., Massachusetts Fed'n of Teachers,
    AFT, AFL-CIO v. Board of Educ., 
    436 Mass. 763
    , 773 (2002).24
    The broad-ranging authority evinces the Legislature's
    determination that the Secretary is best "suited to the task of
    clarifying the Legislature's plan through specific rules,"
    23The Secretary is delegated the authority to, for example,
    investigate and sanction misconduct under MUSA by broker-
    dealers, including by issuing subpoenas and cease-and-desist
    orders, and levying fines or other sanctions. G. L. c. 110A,
    §§ 204, 407, 407A.
    24In Massachusetts Fed'n of Teachers, AFT, AFL-CIO, 436
    Mass. at 773, we recognized that a rulemaking delegation
    provision akin to MUSA's -- providing the Board of Education
    with the "authority to promulgate, amend[,] and rescind such
    rules and regulations as may be necessary to carry out the
    provisions of [the educator qualifications section of the
    Education Reform Act]," see id. at 768, quoting G. L. c. 71,
    § 38G -- gave the agency broad authority to adopt regulations to
    fulfill the statutory mandate.

    Goldberg v. Board of Health of Granby, 
    444 Mass. 627
    , 633-634
    (2005), and its conclusion that the Secretary, because of his
    "experience, technical competence, and specialized knowledge" is
    well positioned to address the program of reform at issue, Souza
    v. Registrar of Motor Vehicles, 
    462 Mass. 227
    , 229 (2012),
    quoting G. L. c. 30A, § 14 (7), which in the case of MUSA is
    investor protection, see Bulldog Investors Gen. Partnership, 
    460 Mass. at 652, 655
    .   Relevant here, the "Legislature's silence"
    as to the particular "conduct or practice" deemed to be
    "unethical or dishonest" for purposes of an enforcement action
    under G. L. c. 110A, § 204 (a) (2) (G),25 coupled with the wide
    authorization given to the Secretary under MUSA, constitutes "an
    invitation to [the Secretary] to fill the gap with appropriate
    regulation."   McCauley v. Superintendent, Mass. Correctional
    Inst., Norfolk, 
    491 Mass. 571
    , 585-586 (2023), quoting
    Massachusetts Teachers' Retirement Sys. v. Contributory
    Retirement Appeal Bd., 
    466 Mass. 292
    , 301 (2013).   See, e.g.,
    Purity Supreme, Inc. v. Attorney Gen., 
    380 Mass. 762
    , 771 (1980)
    25Robinhood mistakenly asserts that the Secretary's
    definition of "unethical or dishonest conduct or practices" to
    include the failure to abide by the fiduciary duty rule is
    inconsistent with the dictionary definitions of those terms.
    See Black's Law Dictionary 790 (4th rev. ed. 1968) (defining
    "fraudulent or dishonest act" as one that "involves bad faith, a
    breach of honesty, a want of integrity, or moral turpitude");
    id. at 1698 (defining "unethical" as "not according to business
    or professional standards").
    23
    ("The purpose of an open-ended legislative use of the words
    'unfair' and 'deceptive' [in G. L. c. 93A, the consumer
    protection statute] was to allow for the regulation [by the
    Attorney General] of future, as-yet-undevised, business
    practices").
    Pursuant to this expansive authority, before adopting the
    fiduciary duty rule, the Secretary considered, inter alia, the
    Securities Division's enforcement experience, empirical studies,
    the Section 913 study and its recommendations, and public
    comments related to the relationship between broker-dealers and
    their customers.   See generally Solicitation of Comments, supra.
    Many investors, these sources highlighted, did not understand
    the different standards of care required of broker-dealers and
    investment advisers because of the increasingly blurred lines
    between the two as broker-dealers expanded their offerings,
    changed their marketing to the public, and moved to different
    compensation models.   Increasingly, investors mistakenly
    believed that the broker-dealers had a fiduciary obligation
    equal to investment advisers to act in their customers' best
    interests, as discussed supra, and this mistake resulted in
    investor harm.26   See Section 913 study, supra at v.   Indeed, the
    26See A.A. Hung, N. Clancy, J. Dominitz, E. Talley, C.
    Berrebi, & F. Suvankulov, RAND Institute for Civil Justice,
    Investor and Industry Perspectives on Investment Advisers and
    24
    recommendation of the authors of the report following the
    Section 913 study, which conducted a comprehensive investigation
    at the national level, also was to impose a "uniform fiduciary
    standard" applicable to both broker-dealers and investment
    advisers, in order to best protect investors.   Id.
    As a result of the Secretary's investigation, he concluded
    that the fiduciary duty rule best ensured that MUSA's
    protections aligned with investors' expectations in the evolving
    investment landscape.   Accordingly, the Secretary determined
    that the fiduciary duty rule was necessary to fulfill MUSA's
    broad investor protection purpose, consistent with the
    Secretary's obligation to police "unethical or dishonest conduct
    or practices," pursuant to G. L. c. 110A, § 204 (a) (2) (G).
    i.   Industry norms.   Despite the authority given to the
    Secretary under MUSA, Robinhood maintains that, because MUSA
    proscribes "any unethical or dishonest conduct or practices in
    the securities, commodities[,] or insurance business" (emphasis
    added), G. L. c. 110A, § 204 (a) (2) (G), the Legislature
    implicitly adopted a standard of care limited to existing
    Broker-Dealers 115 (2008) ("the industry is becoming
    increasingly complex and intertwined and . . . investors do not
    operate with a clear understanding of the different functions
    and fiduciary responsibilities of their financial
    professionals"); id. at 113 (household investor study revealed
    that "the roles of broker-dealers and investment advisers are
    confusing to most survey respondents and focus-group
    participants").
    25
    industry norms, which traditionally have treated broker-dealers
    differently from investment advisers as regards the standard of
    care owed to customers.   This argument fails to consider the
    extensive record relied on by the Secretary showing that the
    industry has strayed from the traditional model for the
    provision of investor services, as broker-dealers have changed
    their offerings, marketing, and compensation models.     See
    discussion supra.
    In response to this industry change and the resulting
    investor confusion and harm, the SEC already altered "industry
    norms," by imposing on broker-dealers increased fiduciary
    obligations under the Regulation Best Interest; and, concluding
    that those were insufficiently clear to address investor
    confusion, the Secretary adopted a uniform fiduciary duty rule.
    To be sure, the rule imposes an obligation on broker-dealers
    beyond that attendant to the prior suitability standard, see
    supra, and is clearer than the standard under Regulation Best
    Interest, which does not define "best interest."   But the rule
    is driven by changes in the prior "norms" of the marketplace
    that have caused investor harm, the Secretary found.27
    27Contrary to Robinhood's argument, the fact that other
    State courts, in assessing the constitutionality of the phrase
    "unethical or dishonest conduct or practices" against charges of
    vagueness, construed "unethical or dishonest conduct or
    practices" through the lens of industry norms does not confine
    26
    Consistent with his extensive authority and the flexibility
    it necessarily portends, the Secretary permissibly adapted the
    standard of care required of these new-age broker-dealers, who
    have themselves adopted new business models inconsistent with
    their traditional roles and prior industry norms,28 to carry out
    his charge under MUSA to protect investors, see Marram v.
    Kobrick Offshore Fund, Ltd., 
    442 Mass. 43
    , 54 (2004) (MUSA has
    "consumer-oriented focus").   MUSA authorizes the Secretary to
    define the phrase "unethical or dishonest conduct or practices,"
    so long as he does so consistent with the purpose of MUSA to
    protect investors; his determination that the fiduciary duty
    rule was necessary for that purpose is owed deference, where, as
    here, the conclusion is supported by the extensive regulatory
    the phrase to existing industry standards of care here, where
    the phrase is defined by regulation. See, e.g., Brewster v.
    Maryland Sec. Comm'r, 
    76 Md. App. 722
    , 728-729 (1988); Johnson-
    Bowles Co. v. Division of Sec. of the Dep't of Commerce of Utah,
    
    829 P.2d 101
    , 112 (Utah Ct. App. 1992).
    28We disagree that the phrase "in the securities,
    commodities[,] or insurance business" suggests a Legislative
    intent to circumscribe the Secretary's authority to then-
    existing industry norms. Rather, the phrase specifies the
    relevant context to which the provision applies -- namely, "in
    the securities, commodities[,] or insurance business," and not
    in other types of businesses, as the drafters of the provision
    explained. See L. Loss, Commentary on the Uniform Securities
    Act, draftsmen's commentary to § 204, at 32 (1976) (phrase
    "limited to dishonest and unethical practices in the securities
    business," not in "the myriad forms of business generally in
    which an applicant may have engaged"). See also Marram v.
    Kobrick Offshore Fund, Ltd., 
    442 Mass. 43
    , 50-53, 56 (2004)
    (citing drafters' commentary as persuasive authority).
    27
    record.   See Goldberg, 
    444 Mass. at 633-634
     (State agency has
    "considerable leeway in interpreting a statute it is charged
    with enforcing, unless a statute unambiguously bars the agency's
    approach" [quotation and citation omitted]).
    ii.   Policy of uniformity.   Robinhood next asserts that the
    fiduciary duty rule cannot be reconciled with G. L. c. 110A,
    § 415, which provides that MUSA "shall be so construed as to
    effectuate its general purpose to make uniform the law of those
    [S]tates which enact it and to coordinate the interpretation and
    administration of this chapter with the related [F]ederal
    regulation."   We already have rejected the argument that this
    provision "mandate[s] that [State] courts adopt the
    interpretation of comparable Federal [and State] securities
    statutes," see Hays v. Ellrich, 
    471 Mass. 592
    , 605, cert.
    denied, 
    577 U.S. 985
     (2015); we see no reason why it would
    require the Secretary to do so in this context -– a point
    confirmed by the provision's drafters.   See L. Loss, Commentary
    on the Uniform Securities Act, draftsmen's commentary to § 415,
    at 165 (1976) (§ 415 was not intended to mean "that a [S]tate
    court or Administrator is required to follow a judicial or
    28
    administrative precedent set by another [S]tate or by the
    SEC").29
    Nor does G. L. c. 110A, § 412 (b), support Robinhood's
    position.    It states that the Secretary "may cooperate with the
    securities administrators of the other [S]tates and the [SEC]"
    when "prescribing rules and forms," "with a view to effectuating
    the policy of this statute to achieve maximum uniformity in the
    form and content of registration statements, applications, and
    reports wherever practicable" (emphasis added).    G. L. c. 110A,
    § 412 (b).   The plain text does not require uniformity in the
    Secretary's determination of substantive policy.30
    At bottom, Robinhood's arguments "reduce[] to the
    proposition that, had it been charged with enforcing [MUSA],
    [it] would have chosen a different regulatory approach,"
    29Robinhood's proposed construction of G. L. c. 110A,
    § 415, would freeze the ability to adapt to changes in the
    industry that require new standards of conduct. Pursuant to
    MUSA, the Legislature authorized the Secretary -- not the SEC or
    sister States' regulatory agencies -- to promulgate rules
    responsive to industry changes. See Ciampi v. Commissioner of
    Correction, 
    452 Mass. 162
    , 168 (2008) ("When the Legislature
    vests an agency with broad authority to effectuate the purposes
    of an act the validity of a regulation promulgated thereunder
    will be sustained so long as it is reasonably related to the
    purposes of the enabling legislation" [quotations and citation
    omitted]).
    30Even with regard to forms, registration statements,
    applications and reports, the requirement applies only to the
    extent feasible. See Black's Law Dictionary 1335 (4th rev. ed.
    1968) (defining "practicable" as "performable, feasible,
    possible").
    29
    Goldberg, 
    444 Mass. at 635
    .    But our task is not to pass
    judgment on the wisdom of the policy.    We conclude only that the
    Secretary had the discretion to make that determination, and
    that, in view of the record of investor harm, his ability to do
    so falls within the authority bequeathed to him under MUSA.
    c.   Common law.    Robinhood next argues that the fiduciary
    duty rule is invalid because it abrogates the common law as set
    forth in Patsos v. First Albany Corp., 
    433 Mass. 323
     (2001).       We
    disagree.
    As we explained in Patsos, under the common law, a
    "relationship between a [broker-dealer] and a customer may be
    either a fiduciary or an ordinary business relationship,
    depending on whether the customer provides sufficient evidence
    to prove 'a full relation of principal and broker.'"     Patsos,
    
    433 Mass. at 331-332
    .     The determination of the "scope of a
    [broker-dealer's] fiduciary duties in a particular case is a
    factual issue that turns on the manner in which investment
    decisions have been reached and transactions executed for the
    account."   
    Id. at 332
    .   We observed that where broker-dealers
    are entrusted with investment discretion, they "assume[] broad
    fiduciary obligations that extend beyond individual
    transactions."   
    Id. at 333
    .   But where the "the customer makes
    the investment decisions and the stockbroker merely receives and
    30
    executes a customer's orders, the relationship generally does
    not give rise to general fiduciary duties."   
    Id.
    In each case, the fact-intensive inquiry is guided by "two
    potentially competing considerations:   the need to protect
    customers who relinquish control of their brokerage accounts,
    and the need to ensure that securities broker[-dealers] --
    particularly those who merely execute purchase and sell orders
    for customers -- not become insurers of their customers'
    investments."   Patsos, 
    433 Mass. at 336
    .   We concluded that
    "[a]ssigning general fiduciary duties only to those stockbrokers
    who have the ability to, and in fact do, make most if not all of
    the investment decisions for their customers properly provides
    appropriate protection only for those customers who are
    particularly vulnerable to a broker's wrongful activities."      
    Id.
    Contrary to Robinhood's assertions, the fiduciary duty rule
    does not abrogate the common law.   Instead, the rule, which has
    the force of law, see Borden, Inc. v. Commissioner of Pub.
    Health, 
    388 Mass. 707
    , 723, cert. denied sub nom. Formaldehyde
    Inst., Inc. v. Frechette, 
    464 U.S. 936
    , (1983), is of equal
    status to the common law, see Commonwealth v. Adams, 
    482 Mass. 514
    , 518 (2019).   The Legislature can provide, and under MUSA
    has provided, protections that may extend beyond those available
    under the common law without abrogating the latter.    In other
    words, the rights and protections afforded under MUSA, including
    31
    those available under the fiduciary duty rule, stand shoulder-
    to-shoulder with those under the common law.31    Thus, for
    example, an investor injured by a breach of a fiduciary duty may
    have a claim under the fact-intensive inquiry delineated in
    Patsos, whereas the fiduciary duty rule provides a separate and
    distinct regulatory tool to protect investors under MUSA.
    This conclusion is not novel.    We have previously
    acknowledged that MUSA provides protections beyond -- without
    overriding -- the common law.    See, e.g., Bulldog Investors Gen.
    Partnership v. Secretary of the Commonwealth, 
    457 Mass. 210
    , 220
    (2010) (definition of term "offer" under MUSA "not limited to
    its common-law definition").    See also Welch v. Barach, 
    84 Mass. App. Ct. 113
    , 119-120 (2013) (MUSA misrepresentation claim does
    not require two elements of common-law tortious
    misrepresentation).32
    31Indeed, the Legislature anticipated that MUSA's
    protections would go beyond the common law. See, e.g., G. L.
    c. 110A, § 401 (d) (for purposes of MUSA, "fraud," "deceit," and
    "defraud" are "not limited to common-law deceit").
    32The Legislature may craft statutory obligations that
    exceed the common law, authorizing a State official or agency to
    define the scope of those obligations. For example, G. L.
    c. 93A "created new substantive rights by making conduct
    unlawful which was not unlawful under the common law," such as
    "[u]nfair and deceptive practices" beyond those "limited by
    traditional tort and contract law requirements," Slaney v.
    Westwood Auto, Inc., 
    366 Mass. 688
    , 693 (1975), quoting
    Commonwealth v. DeCotis, 
    366 Mass. 234
    , 244 n.8 (1974), and
    authorized the Attorney General to enforce the new protections,
    32
    d.   Nondelegation doctrine.    Robinhood also maintains that,
    if MUSA permits the Secretary to promulgate the fiduciary duty
    rule, as we conclude it does, then MUSA impermissibly delegates
    legislative authority in violation of the separation of powers
    doctrine embodied in article 30 of the Massachusetts Declaration
    of Rights (art. 30).33   Article 30 "encompasses the general
    principle that the Legislature cannot delegate the power to make
    laws."    Construction Indus. of Mass. v. Commissioner of Labor &
    Indus., 
    406 Mass. 162
    , 171 (1989).    "No formula exists for
    determining whether a delegation of legislative authority is
    'proper,'" Chelmsford Trailer Park, Inc. v. Chelmsford, 
    393 Mass. 186
    , 190 (1984), but three considerations are relevant:
    "(1) Did the Legislature delegate the making of fundamental
    policy decisions, rather than just the implementation of
    legislatively determined policy; (2) does the act provide
    adequate direction for implementation, either in the form
    of statutory standards or . . . sufficient guidance to
    including by promulgating rules to define the actions that
    constitute "unfair or deceptive acts or practices in the conduct
    of any trade or commerce," Slaney, supra at 694-695 & n.7,
    quoting G. L. c. 93A, § 2. Likewise, G. L. c. 151B supplemented
    protections available to employees under the common law and
    authorized the Massachusetts Commission Against Discrimination
    to make rules to that effect. See G. L. c. 151B § 3 (5). See
    also Green v. Wyman-Gordon Co., 
    422 Mass. 551
    , 558 (1996) (G. L.
    c. 151B claims are separate from common-law claims for
    intentional and negligent infliction of emotional distress).
    33Article 30 of the Massachusetts Declaration of Rights
    provides, in relevant part, that "[i]n the government of this
    [C]ommonwealth, . . . the executive shall never exercise the
    legislative and judicial powers, or either of them: . . . to the
    end it may be a government of laws and not of men."
    33
    enable it to do so; and (3) does the act provide safeguards
    such that abuses of discretion can be controlled?"
    
    Id.
       See Oracle USA, Inc. v. Commissioner of Revenue, 
    487 Mass. 518
    , 525 (2021), quoting Gundy v. United States, 
    139 S. Ct. 2116
    , 2123 (2019) ("Delegation is constitutional so long as the
    legislative body provides an 'intelligible principle' to direct
    the exercise of delegated authority").   We address each
    consideration in turn.
    First, MUSA sets forth the Legislature's fundamental policy
    decision to protect investors, and more specifically to protect
    them from "unethical or dishonest conduct or practices," G. L.
    c. 110A, § 204 (a) (2) (G).   Delegating the authority to define
    the precise conduct or practices proscribed is not tantamount to
    permitting the Secretary to determine fundamental policy
    decisions.   See, e.g., Commonwealth v. Clemmey, 
    447 Mass. 121
    ,
    136 (2006) (Legislature's "delegation of the definitions . . .
    simply directed the [agency] to work out the details necessary
    to the implementation of the policy").   Such a delegation
    permissibly draws on the Secretary's expertise to adapt to the
    real-world context of evolving practices in the securities
    industry, including, as relevant here, the changes resulting
    from broker-dealers increasingly choosing to give investment
    advice and blurring the line that traditionally separated
    broker-dealers from investment advisers, as delineated in part
    34
    2.a, supra.   See, e.g., Clemmey, 
    supra at 137
     (delegation of
    power to agency to define terms used in Wetlands Protection Act
    agricultural exemption proper "because it ensured that the scope
    of the agricultural exemption would be based on the application
    of real-world farming practices").34
    Second, the Secretary is not without guidance in defining
    the proscribed practices.   See Chelmsford Trailer Park, Inc.,
    
    393 Mass. at 190
    .   MUSA allows the Secretary to define such
    conduct and practices only "insofar as the definitions are not
    inconsistent with the provisions of [MUSA]," G. L. c. 110A,
    § 412 (a); regulations also must be "necessary or appropriate in
    the public interest or for the protection of investors and
    consistent with the purposes fairly intended by the policy and
    provisions of [MUSA]."   Id. § 412 (b).   These provisions provide
    an intelligible principle to direct the Secretary's exercise of
    his authority.   See, e.g., Clemmey, 
    447 Mass. at 137
     (statute's
    guidance sufficient where it generally specified concern for
    land "owned and managed by farmers," jeopardy to "the future
    economic viability of our farms," and "routine and long standing
    34Accord United States vs. Levoff, U.S. Dist. Ct., No. 19-
    cr-780 (D.N.J. Aug. 12, 2020) (SEC regulations outlawing insider
    trading did not violate nondelegation doctrine because
    Securities and Exchange Act of 1934 delegated power to SEC to
    enact securities regulations toward goal of "insur[ing] the
    maintenance of fair and honest markets in [securities]
    transactions" [quotation and citation omitted]).

    farm operations," and was amended from "land for agricultural
    use" to "land in agricultural use" [emphasis added; citations
    omitted]); Tri-Nel Mgt., Inc. v. Board of Health of Barnstable,
    
    433 Mass. 217
    , 226 (2001) (statute's guidance sufficient where
    it required "reasonable" regulations to "address the 'health' of
    the community" [citations omitted]).
    Third, MUSA provides safeguards such that any abuse of
    discretion "can be controlled," see Chelmsford Trailer Park,
    Inc., 
    393 Mass. at 190
    .   Before promulgating regulations, the
    Secretary must make findings that any rule promulgated pursuant
    to MUSA is "necessary or appropriate in the public interest or
    for the protection of investors and consistent with the purposes
    fairly intended by the policy and provisions of [MUSA]."      G. L.
    c. 110A, § 412 (b).   Entities subject to an administrative
    action are entitled to notice and a hearing, G. L. c. 110A,
    § 305 (b), and may obtain judicial review of such actions, see
    G. L. c. 30A, § 14; G. L. c. 110A, § 411 (a).35   See Clemmey, 447
    35Robinhood mistakenly contends that permitting the
    Secretary to define "unethical or dishonest conduct or
    practices," G. L. c. 110A, § 204 (a) (2) (G), by reference to
    the fiduciary duty rule, presents due process concerns in that
    it renders MUSA "so standardless that it invites arbitrary
    enforcement" (citation omitted), Beckles v. United States, 
    580 U.S. 256
    , 262 (2017). "A law is void for vagueness if persons
    of common intelligence must necessarily guess at its meaning and
    differ as to its application . . . or if it subjects people to
    an unascertainable standard" (citation omitted). Commonwealth
    v. Cassidy, 
    479 Mass. 527
    , 538, cert. denied, 
    139 S. Ct. 276
    36
    Mass. at 138 ("the availability of judicial review" weighs in
    favor of conclusion that law "sufficiently demarcate[s] the
    boundaries of regulatory discretion" [citation omitted]).36
    e.   Conflict preemption.   Robinhood alternatively argues
    that the fiduciary duty rule is invalid under the doctrine of
    conflict preemption, contending that the rule "stands as an
    obstacle to the accomplishment and execution of the full
    purposes and objectives of [the Federal government]," Marsh v.
    Massachusetts Coastal R.R., 
    492 Mass. 641
    , 648 n.18 (2023),
    quoting Sprietsma v. Mercury Marine, 
    537 U.S. 51
    , 64 (2002), as
    those purposes and objectives are set forth in the SEC's
    Regulation Best Interest.   See Merck Sharp & Dohme Corp. v.
    Albrecht, 
    139 S. Ct. 1668
    , 1679 (2019) (Federal regulation
    issued pursuant to statutorily delegated authority can preempt
    State law).   Robinhood asserts that the SEC intended the
    Regulation Best Interest to set a ceiling on broker-dealers'
    (2018). Tellingly, the fiduciary duty rule essentially imposes
    obligations already well understood by investment advisers. See
    Section 913 study, supra at vi-vii (investment advisers are
    subject to duties of loyalty and care).
    36Our decision in Clemmey, 
    447 Mass. at 135-136
    , disposes
    of Robinhood's concern that the Secretary's interpretation vests
    him with the effective "authority to establish new crimes," see
    G. L. c. 110A, § 409 (a). As we explained, the Legislature may,
    with sufficient guardrails, delegate to an agency the definition
    of criminal conduct; such a delegation does not violate due
    process where "fair notice of the conduct proscribed has been
    provided," Clemmey, 
    supra at 136
    , as was provided here.
    37
    fiduciary obligations to preserve retail investor access to
    investment options that, Robinhood predicts, may become
    economically unfeasible for broker-dealers to continue to offer
    if they must comply with the fiduciary duty rule.
    i.     Assumption against preemption.   "[P]re-emption
    fundamentally is a question of congressional intent."         Geier v.
    American Honda Motor Co., 
    529 U.S. 861
    , 884 (2000), quoting
    English v. General Elec. Co., 
    496 U.S. 72
    , 78 (1990).         Our
    analysis "begins 'with the assumption that the historic police
    powers of the States [are] not to be superseded by . . . Federal
    Act unless that [is] the clear and manifest purpose of
    Congress.'"    Dunn v. Genzyme Corp., 
    486 Mass. 713
    , 718 (2021),
    quoting Cipollone v. Liggett Group, Inc., 
    505 U.S. 504
    , 516
    (1992).37    Because State securities laws, like MUSA, fall within
    a field of "'traditional' [S]tate regulation," the assumption
    guides our analysis.     Oneok, Inc. v. Learjet, Inc., 
    575 U.S. 373
    , 374 (2015).
    Moreover, where, as here, "coordinate[d] [S]tate and
    [F]ederal efforts exist within a complementary administrative
    framework, and in the pursuit of common purposes, the case for
    37This assumption reflects that "the States are independent
    sovereigns in our [F]ederal system," and is consistent with "the
    historic primacy of [S]tate regulation of matters of health and
    safety." Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 485 (1996)
    (plurality opinion).
    38
    [F]ederal pre-emption becomes a less persuasive one."    New York
    State Dep't of Social Servs. v. Dublino, 
    413 U.S. 405
    , 421
    (1973).   State and Federal schemes have existed side by side
    since the Great Depression;38 and Congress repeatedly has
    expressed its intent to preserve the States' role in regulating
    securities.39    See Capital Research & Mgt. Co. v. Brown, 
    147 Cal. App. 4th 58
    , 66 (2007) ("Congress intended to preserve the
    [S]tates' anti-fraud authority to control the conduct of brokers
    and dealers").    In this context, a party asserting conflict
    preemption bears a heavy burden to demonstrate "evidence of
    conflict, and not merely with unsupported pronouncements as to
    [Federal] policy" (quotation and citation omitted).     Roberts v.
    Southwestern Bell Mobile Sys., Inc., 
    429 Mass. 478
    , 491 (1999).
    38"Securities regulation has existed, in one form or
    another, since the mid-1800s," and "[b]efore the Great
    Depression, securities were regulated almost exclusively by the
    [S]tates." Lindeen v. Securities & Exch. Comm'n, 
    825 F.3d 646
    ,
    648-649 (D.C. Cir. 2016). "[B]eginning with Kansas in 1911,
    many states imposed comprehensive securities regulation regimes
    . . . [k]nown as 'blue-sky' laws." 
    Id. at 649
    . During the
    Great Depression, Congress began regulating securities at the
    Federal level, enacting the Securities Act of 1933, 15 U.S.C.
    §§ 77a-77aa, and thereafter the Securities Exchange Act of 1934,
    15 U.S.C. §§ 78a-78pp, which created the SEC. See Lindeen,
    
    supra.
    39See, e.g., 15 U.S.C. § 77r(c)(1) (preempting State
    securities registration and qualification regimes for some
    offerings but specifying that States "retain jurisdiction . . .
    to investigate and bring enforcement actions, [in connection
    with securities or securities transactions]" with respect to
    "fraud or deceit" or "unlawful conduct by a broker").
    39
    See Chamber of Commerce of the U.S. v. Whiting, 
    563 U.S. 582
    ,
    607 (2011) ("a high threshold must be met if a [S]tate law is to
    be preempted for conflicting with the purposes of a [F]ederal
    [a]ct" [citation omitted]).   Only "affirmative evidence that
    Congress . . . had a ceiling-setting -- and thus obstacle-
    preemption-creating -- intent" will suffice.   Capron v. Office
    of the Attorney Gen. of Mass., 
    944 F.3d 9
    , 28 (1st Cir. 2019),
    cert. denied, 
    141 S. Ct. 150 (2020)
    .
    Here, Robinhood's preemption argument is "particularly
    weak" because Congress and the SEC were aware of State laws
    imposing fiduciary obligations on broker-dealers and declined to
    express an intent to preempt those laws.   See Wyeth v. Levine,
    
    555 U.S. 555
    , 575 (2009) ("The case for [F]ederal preemption is
    particularly weak where [the Federal government] has indicated
    its awareness of the operation of [S]tate law in a field of
    [F]ederal interest, and has nonetheless decided to stand by both
    concepts and to tolerate whatever tension there [is] between
    them" [citation omitted]).    When it enacted Dodd-Frank with the
    purpose "to protect consumers from abusive financial services
    practices," Dodd-Frank preamble, 124 Stat. at 1376, Congress
    instructed the SEC to look to the "legal or regulatory standards
    of State securities regulators and other regulators intended to
    protect retail customers," as models for the agency's own
    efforts to derive a new standard for broker-dealers.    See Dodd-
    40
    Frank § 913(c)(8), 124 Stat. at 1826.   The SEC did so,40 and in
    adopting the Regulation Best Interest, the SEC observed that
    "[s]ome [S]tates provide through statute or regulation, among
    other requirements . . . that broker-dealers have some form of
    [S]tate-specific fiduciary duty to their customers in at least
    some circumstances," 84 Fed. Reg. at 33,419,41 and "courts
    40See Section 913 study, supra at 91 ("many [S]tates
    require broker-dealers and their agents to observe high
    standards of commercial honor and just and equitable principles
    of trade in the conduct of business, and/or prohibit a variety
    of enumerated unethical or fraudulent practices").
    41For example, the State of Nevada "passed a law in 2017
    that imposes a fiduciary duty on broker-dealers, sales
    representatives, and investment advisers who give investment
    advice." University of Miami School of Law, Comment Letter on
    "Regulation Best Interest" Proposal, Nos. S7-07-18, 34-38062,

    Secretary of State proposed regulations pursuant to the Nevada

    42
    In promulgating the Regulation Best Interest, the SEC
    "recognize[d] that there is substantial variation in the
    sources, scope, and application of [S]tate fiduciary law."     84
    Fed. Reg. at 33,435.43   Yet the SEC declined to indicate whether,
    in its perspective, the Regulation Best Interest preempted State
    laws, as some commenters urged it to do, stating that it could
    not "analyze the economic effects of the possible preemption of
    [S]tate law at [that] point because the factors that [would]
    shape those judicial determinations [were] too speculative."    84
    Fed. Reg. at 33,435 n.1163.
    ii.   Regulation Best Interest sets a floor.   Against this
    backdrop, Robinhood's theory of conflict preemption is grounded
    "States that impose a limited fiduciary duty include
    Delaware, Florida, Georgia, Illinois, Kansas, Louisiana,
    Maryland, Michigan, Ohio, Pennsylvania, Tennessee, and Texas."
    Finke & Langdon, supra at 33. See, e.g., O'Malley v. Boris, 
    742 A.2d 845
    , 849 (Del. 1999) (broker-dealers have "fiduciary duties
    of good faith, fair dealing, and loyalty" to customers). See
    also Wallace v. Hinkle N.W., Inc., 
    79 Or. App. 177
    , 181 (1985)
    ("A stockbroker is a fiduciary if his client trusts him to
    manage and control the client's account and he accepts that
    responsibility").
    43The SEC acknowledged that broker-dealers in States that
    already imposed fiduciary standards on them might reap cost
    benefits with Regulation Best Interest because "they may already
    engage in practices under the baseline that overlap with certain
    requirements under [the] Regulation Best Interest," 84 Fed. Reg.
    at 33,435, and also that "costs and benefits that arise from
    obligations under Regulation Best Interest that differ from
    obligations under [S]tate law, such as the Conflict of Interest
    Obligation, will be maintained." Id.
    43
    in the SEC's decision not to impose a uniform fiduciary duty
    standard, as well as the SEC's statement that
    "Regulation Best Interest . . . balances the concerns of
    the various commenters in a way that will best achieve the
    Commission's important goals of enhancing retail investor
    protection and decision making, while preserving, to the
    extent possible, retail investor access (in terms of choice
    and cost) to differing types of investment services and
    products" (emphasis added).
    84 Fed. Reg. at 33,323.   We disagree that this aspiration to
    preserve investor access to an array of investor services "to
    the extent possible" hurdles the high bar required to find
    conflict preemption.   See Kansas v. Garcia, 
    140 S. Ct. 791
    , 801
    (2020) (cautioning against "[i]nvoking some brooding [F]ederal
    interest" as basis for conflict preemption [citation omitted]).
    Indeed, although the SEC mentioned one short-lived experiment to
    suggest that a higher fiduciary obligation might cause broker-
    dealers to pass along increased costs to customers or to alter
    their existing offerings,44 the SEC declined invitations to
    44In particular, the Department of Labor had promulgated
    regulations pursuant to the Employee Retirement Income Security
    Act of 1974, 
    Pub. L. No. 93-406, 88
     Stat. 829, codified as
    amended at 
    29 U.S.C. §§ 1001
     et seq. (ERISA), through which most
    broker-dealers would be deemed fiduciaries when they provided
    recommendations to retirement plan investors. 
    29 C.F.R. § 2510.3
    –21(a)(2)(iii), (d) (2017) (DOL Fiduciary Rule),
    repealed in part by 
    85 Fed. Reg. 40589
     (July 7, 2020). The SEC
    explained that "the full effects of the DOL Fiduciary Rule were
    not realized as it was vacated during the transition period,"
    stating only that "a number of industry studies indicated that,
    as a result of the DOL Fiduciary Rule, industry participants had

    assess any preemptive effects of the Regulation Best Interest on
    State regulations as "too speculative."    84 Fed. Reg. at 33,325
    & n.61, 33,435 n.1163.
    The Supreme Court's decision in Williamson v. Mazda Motor
    of Am., Inc., 
    562 U.S. 323
    , 332 (2011), is instructive.       There,
    the Supreme Court considered whether a State tort claim, which
    would effectively require lap-and-shoulder belts in the rear
    middle seat of cars, was preempted because it ostensibly
    presented a conflict with a Federal safety regulation that, for
    cost-savings reasons, gave manufacturers a choice as to the type
    of restraint system to install in the rear seat.    
    Id. at 326
    .
    The Court determined that the State tort action was not
    preempted because cost savings was not a "significant regulatory
    objective."   
    Id. at 332
    .   The Supreme Court reasoned that
    "to infer from the mere existence of such a cost-
    effectiveness judgment that the [F]ederal agency intend[ed]
    to bar States from imposing stricter standards would treat
    all such [F]ederal standards as if they were maximum
    standards, eliminating the possibility that the [F]ederal
    agency [sought] only to set forth a minimum standard
    potentially supplemented through [S]tate tort law."
    available to retail customers." 84 Fed. Reg. at 33,322 & n.33.
    See id. at 33,322 n.34 ("It was widely reported that a number of
    firms responded to the DOL Fiduciary Rule by either requiring
    customers to enter into more expensive advice relationships or
    by passing through higher compliance costs to customers, which
    altered many retail customer relationships with their financial
    professionals").
    45
    Id. at 336.45
    Like the hoped-for cost savings in Williamson, the SEC's
    wish to "preserv[e], to the extent possible, retail investor
    access" to a variety of investment services and products, 84
    45 Critically, the Supreme Court distinguished this cost-
    saving aspirational goal from the purposes at issue in a prior
    iteration of the same Federal safety regulation, which the Court
    had considered in Geier, a case upon which Robinhood rests its
    preemption argument. Williamson, 562 U.S. at 336. Geier
    concerned whether a State tort claim that effectively would
    require airbags was preempted by a Federal regulation allowing
    manufacturers a choice to install a variety and mix of passive
    restraint systems. See Geier, 
    529 U.S. at 881
    . The Federal
    agency had concluded that permitting a mix of devices "would
    help develop data on comparative effectiveness, would allow the
    industry time to overcome the safety problems and the high
    production costs associated with airbags, and would facilitate
    the development of alternative, cheaper, and safer passive
    restraint systems," and "would thereby build public confidence"
    through a "gradual phase-in" of passive restraint systems. 
    Id. at 879
    . The resulting Federal regulation "embodie[d] the
    [agency's] policy judgment that safety would best be promoted if
    manufacturers installed alternative protection systems in their
    fleets rather than one particular system in every car." 
    Id. at 881
    . The Federal policy to promote safety in vehicles would
    have been undermined by a State claim holding manufacturers
    liable for their failure to install airbags. 
    Id.
     The Court in
    Williamson distinguished the Federal agency's determination in
    Geier, where the "regulation's history, the agency's
    contemporaneous explanation, and its consistently held
    interpretive views indicated that the regulation sought to
    maintain manufacturer choice in order to further significant
    regulatory objectives" (emphasis added), i.e., enhancing safety,
    from the agency's determination in Williamson to permit
    manufacturers to choose either lap or lap-and-shoulder belts for
    rear middle seats for cost-savings reasons. Williamson, supra
    at 336.

    Fed. Reg. at 33,323,46 does not preclude the Secretary from
    imposing a higher duty on broker-dealers that provide investment
    advice.   As both Congress and the SEC have made clear, the
    central "purposes and objectives," Marsh, 492 Mass. at 648 n.18,
    quoting Sprietsma, 
    537 U.S. at 64
    , of Federal law as it pertains
    to broker-dealer standards are to improve investor protection.
    See Dodd-Frank preamble, 124 Stat. at 1376; 84 Fed. Reg. at
    33,323.   Against the backdrop of a long history of State
    regulations of broker-dealer standards existing alongside
    Federal regulations, including States imposing fiduciary duties
    on broker-dealers; a congressional record encouraging the SEC to
    consider imposing a uniform fiduciary duty standard; the Section
    913 study advising the same; and the SEC's conclusion in its
    adopting release that a preemption analysis would be too
    speculative, we conclude that the Regulation Best Interest
    constitutes a regulatory floor that does not foreclose State
    regulation to more clearly protect investors.   See Williamson,
    562 U.S. at 335.   See also Mobil Oil Corp. v. Attorney Gen., 
    361 Mass. 401
    , 410 (1972) (Federal rule was best understood as
    46See, e.g., 
    84 Fed. Reg. 33,322
     ("subject[ing] broker-
    dealers to a wholesale and complete application of the existing
    fiduciary standard under the [Investment] Advisers Act . . .
    would significantly reduce retail investor access to differing
    types of investment services and products, reduce retail
    investor choice in how to pay for those products and services,
    and increase costs for retail investors of obtaining investment
    recommendations").

    regulatory floor to State rule without any "clear indication
    that the States were to be precluded from legislating in [the]
    area").   Robinhood has not met its high burden to demonstrate
    otherwise.   See Roberts, 
    429 Mass. at 491
    .
    4.   Conclusion.   The Superior Court judgment is reversed,
    and the matter is remanded for further proceedings consistent
    with this opinion.47
    So ordered.
    47Because we address only the legal questions presented by
    the parties, we remand the case to the Superior Court for
    consideration of any fact-dependent issues that may remain.
