CHAPTER 2B— SECURITIES EXCHANGES
§ 78k–1. National market system for securities; securities information processors

(a) Congressional findings; facilitating establishment of national market system for securities; designation of qualified securities(1) The Congress finds that—(A) The securities markets are an important national asset which must be preserved and strengthened.
(B) New data processing and communications techniques create the opportunity for more efficient and effective market operations.
(C) It is in the public interest and appropriate for the protection of investors and the maintenance of fair and orderly markets to assure—(i) economically efficient execution of securities transactions;
(ii) fair competition among brokers and dealers, among exchange markets, and between exchange markets and markets other than exchange markets;
(iii) the availability to brokers, dealers, and investors of information with respect to quotations for and transactions in securities;
(iv) the practicability of brokers executing investors’ orders in the best market; and
(v) an opportunity, consistent with the provisions of clauses (i) and (iv) of this subparagraph, for investors’ orders to be executed without the participation of a dealer.
(D) The linking of all markets for qualified securities through communication and data processing facilities will foster efficiency, enhance competition, increase the information available to brokers, dealers, and investors, facilitate the offsetting of investors’ orders, and contribute to best execution of such orders.
(2) The Commission is directed, therefore, having due regard for the public interest, the protection of investors, and the maintenance of fair and orderly markets, to use its authority under this chapter to facilitate the establishment of a national market system for securities (which may include subsystems for particular types of securities with unique trading characteristics) in accordance with the findings and to carry out the objectives set forth in paragraph (1) of this subsection. The Commission, by rule, shall designate the securities or classes of securities qualified for trading in the national market system from among securities other than exempted securities. (Securities or classes of securities so designated hereinafter 11 So in original. Probably should be “are hereinafter”. in this section referred to as “qualified securities”.)
(3) The Commission is authorized in furtherance of the directive in paragraph (2) of this subsection—(A) to create one or more advisory committees pursuant to chapter 10 of title 5 (which shall be in addition to the National Market Advisory Board established pursuant to subsection (d) of this section),22 So in original. The comma probably should not appear. and to employ one or more outside experts;
(B) by rule or order, to authorize or require self-regulatory organizations to act jointly with respect to matters as to which they share authority under this chapter in planning, developing, operating, or regulating a national market system (or a subsystem thereof) or one or more facilities thereof; and
(C) to conduct studies and make recommendations to the Congress from time to time as to the possible need for modifications of the scheme of self-regulation provided for in this chapter so as to adapt it to a national market system.
(b) Securities information processors; registration; withdrawal of registration; access to services; censure; suspension or revocation of registration(1) Except as otherwise provided in this section, it shall be unlawful for any securities information processor unless registered in accordance with this subsection, directly or indirectly, to make use of the mails or any means or instrumentality of interstate commerce to perform the functions of a securities information processor. The Commission, by rule or order, upon its own motion or upon application, may conditionally or unconditionally exempt any securities information processor or class of securities information processors or security or class of securities from any provision of this section or the rules or regulations thereunder, if the Commission finds that such exemption is consistent with the public interest, the protection of investors, and the purposes of this section, including the maintenance of fair and orderly markets in securities and the removal of impediments to and perfection of the mechanism of a national market system: Provided, however, That a securities information processor not acting as the exclusive processor of any information with respect to quotations for or transactions in securities is exempt from the requirement to register in accordance with this subsection unless the Commission, by rule or order, finds that the registration of such securities information processor is necessary or appropriate in the public interest, for the protection of investors, or for the achievement of the purposes of this section.
(2) A securities information processor may be registered by filing with the Commission an application for registration in such form as the Commission, by rule, may prescribe containing the address of its principal office, or offices, the names of the securities and markets for which it is then acting and for which it proposes to act as a securities information processor, and such other information and documents as the Commission, by rule, may prescribe with regard to performance capability, standards and procedures for the collection, processing, distribution, and publication of information with respect to quotations for and transactions in securities, personnel qualifications, financial condition, and such other matters as the Commission determines to be germane to the provisions of this chapter and the rules and regulations thereunder, or necessary or appropriate in furtherance of the purposes of this section.
(3) The Commission shall, upon the filing of an application for registration pursuant to paragraph (2) of this subsection, publish notice of the filing and afford interested persons an opportunity to submit written data, views, and arguments concerning such application. Within ninety days of the date of the publication of such notice (or within such longer period as to which the applicant consents) the Commission shall—(A) by order grant such registration, or
(B) institute proceedings to determine whether registration should be denied. Such proceedings shall include notice of the grounds for denial under consideration and opportunity for hearing and shall be concluded within one hundred eighty days of the date of publication of notice of the filing of the application for registration. At the conclusion of such proceedings the Commission, by order, shall grant or deny such registration. The Commission may extend the time for the conclusion of such proceedings for up to sixty days if it finds good cause for such extension and publishes its reasons for so finding or for such longer periods as to which the applicant consents.
The Commission shall grant the registration of a securities information processor if the Commission finds that such securities information processor is so organized, and has the capacity, to be able to assure the prompt, accurate, and reliable performance of its functions as a securities information processor, comply with the provisions of this chapter and the rules and regulations thereunder, carry out its functions in a manner consistent with the purposes of this section, and, insofar as it is acting as an exclusive processor, operate fairly and efficiently. The Commission shall deny the registration of a securities information processor if the Commission does not make any such finding.
(4) A registered securities information processor may, upon such terms and conditions as the Commission deems necessary or appropriate in the public interest or for the protection of investors, withdraw from registration by filing a written notice of withdrawal with the Commission. If the Commission finds that any registered securities information processor is no longer in existence or has ceased to do business in the capacity specified in its application for registration, the Commission, by order, shall cancel the registration.
(5)(A) If any registered securities information processor prohibits or limits any person in respect of access to services offered, directly or indirectly, by such securities information processor, the registered securities information processor shall promptly file notice thereof with the Commission. The notice shall be in such form and contain such information as the Commission, by rule, may prescribe as necessary or appropriate in the public interest or for the protection of investors. Any prohibition or limitation on access to services with respect to which a registered securities information processor is required by this paragraph to file notice shall be subject to review by the Commission on its own motion, or upon application by any person aggrieved thereby filed within thirty days after such notice has been filed with the Commission and received by such aggrieved person, or within such longer period as the Commission may determine. Application to the Commission for review, or the institution of review by the Commission on its own motion, shall not operate as a stay of such prohibition or limitation, unless the Commission otherwise orders, summarily or after notice and opportunity for hearing on the question of a stay (which hearing may consist solely of the submission of affidavits or presentation of oral arguments). The Commission shall establish for appropriate cases an expedited procedure for consideration and determination of the question of a stay.
(B) In any proceeding to review the prohibition or limitation of any person in respect of access to services offered by a registered securities information processor, if the Commission finds, after notice and opportunity for hearing, that such prohibition or limitation is consistent with the provisions of this chapter and the rules and regulations thereunder and that such person has not been discriminated against unfairly, the Commission, by order, shall dismiss the proceeding. If the Commission does not make any such finding or if it finds that such prohibition or limitation imposes any burden on competition not necessary or appropriate in furtherance of the purposes of this chapter, the Commission, by order, shall set aside the prohibition or limitation and require the registered securities information processor to permit such person access to services offered by the registered securities information processor.
(6) The Commission, by order, may censure or place limitations upon the activities, functions, or operations of any registered securities information processor or suspend for a period not exceeding twelve months or revoke the registration of any such processor, if the Commission finds, on the record after notice and opportunity for hearing, that such censure, placing of limitations, suspension, or revocation is in the public interest, necessary or appropriate for the protection of investors or to assure the prompt, accurate, or reliable performance of the functions of such securities information processor, and that such securities information processor has violated or is unable to comply with any provision of this chapter or the rules or regulations thereunder.
(c) Rules and regulations covering use of mails or other means or instrumentalities of interstate commerce; reports of purchase or sale of qualified securities; limiting registered securities transactions to national securities exchanges(1) No self-regulatory organization, member thereof, securities information processor, broker, or dealer shall make use of the mails or any means or instrumentality of interstate commerce to collect, process, distribute, publish, or prepare for distribution or publication any information with respect to quotations for or transactions in any security other than an exempted security, to assist, participate in, or coordinate the distribution or publication of such information, or to effect any transaction in, or to induce or attempt to induce the purchase or sale of, any such security in contravention of such rules and regulations as the Commission shall prescribe as necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of this chapter to—(A) prevent the use, distribution, or publication of fraudulent, deceptive, or manipulative information with respect to quotations for and transactions in such securities;
(B) assure the prompt, accurate, reliable, and fair collection, processing, distribution, and publication of information with respect to quotations for and transactions in such securities and the fairness and usefulness of the form and content of such information;

(D) assure that all exchange members, brokers, dealers, securities information processors, and, subject to such limitations as the Commission, by rule, may impose as necessary or appropriate for the protection of investors or maintenance of fair and orderly markets, all other persons may obtain on terms which are not unreasonably discriminatory such information with respect to quotations for and transactions in such securities as is published or distributed by any self-regulatory organization or securities information processor;
(E) assure that all exchange members, brokers, and dealers transmit and direct orders for the purchase or sale of qualified securities in a manner consistent with the establishment and operation of a national market system; and
(F) assure equal regulation of all markets for qualified securities and all exchange members, brokers, and dealers effecting transactions in such securities.
(2) The Commission, by rule, as it deems necessary or appropriate in the public interest or for the protection of investors, may require any person who has effected the purchase or sale of any qualified security by use of the mails or any means or instrumentality of interstate commerce to report such purchase or sale to a registered securities information processor, national securities exchange, or registered securities association and require such processor, exchange, or association to make appropriate distribution and publication of information with respect to such purchase or sale.
(3)(A) The Commission, by rule, is authorized to prohibit brokers and dealers from effecting transactions in securities registered pursuant to section 78l(b) of this title otherwise than on a national securities exchange, if the Commission finds, on the record after notice and opportunity for hearing, that—(i) as a result of transactions in such securities effected otherwise than on a national securities exchange the fairness or orderliness of the markets for such securities has been affected in a manner contrary to the public interest or the protection of investors;
(ii) no rule of any national securities exchange unreasonably impairs the ability of any dealer to solicit or effect transactions in such securities for his own account or unreasonably restricts competition among dealers in such securities or between dealers acting in the capacity of market makers who are specialists in such securities and such dealers who are not specialists in such securities, and
(iii) the maintenance or restoration of fair and orderly markets in such securities may not be assured through other lawful means under this chapter.
The Commission may conditionally or unconditionally exempt any security or transaction or any class of securities or transactions from any such prohibition if the Commission deems such exemption consistent with the public interest, the protection of investors, and the maintenance of fair and orderly markets.
(B) For the purposes of subparagraph (A) of this paragraph, the ability of a dealer to solicit or effect transactions in securities for his own account shall not be deemed to be unreasonably impaired by any rule of an exchange fairly and reasonably prescribing the sequence in which orders brought to the exchange must be executed or which has been adopted to effect compliance with a rule of the Commission promulgated under this chapter.
(4) The Commission is directed to review any and all rules of national securities exchanges which limit or condition the ability of members to effect transactions in securities otherwise than on such exchanges.

The study shall examine the impact that decimalization has had on the number of initial public offerings since its implementation relative to the period before its implementation. The study shall also examine the impact that this change has had on liquidity for small and middle capitalization company securities and whether there is sufficient economic incentive to support trading operations in these securities in penny increments. Not later than 90 days after April 5, 2012, the Commission shall submit to Congress a report on the findings of the study.
(B) Designation.—If the Commission determines that the securities of emerging growth companies should be quoted and traded using a minimum increment of greater than $0.01, the Commission may, by rule not later than 180 days after April 5, 2012, designate a minimum increment for the securities of emerging growth companies that is greater than $0.01 but less than $0.10 for use in all quoting and trading of securities in any exchange or other execution venue.
(d) National Market Advisory Board(1) Not later than one hundred eighty days after June 4, 1975, the Commission shall establish a National Market Advisory Board (hereinafter in this section referred to as the “Advisory Board”) to be composed of fifteen members, not all of whom shall be from the same geographical area of the United States, appointed by the Commission for a term specified by the Commission of not less than two years or more than five years.

(B) The Advisory Board shall study the possible need for modifications of the scheme of self-regulation provided for in this chapter so as to adapt it to a national market system, including the need for the establishment of a new self-regulatory organization (hereinafter in this section referred to as a “National Market Regulatory Board” or “Regulatory Board”) to administer the national market system. In the event the Advisory Board determines a National Market Regulatory Board should be established, it shall make recommendations as to:(i) the point in time at which a Regulatory Board should be established;
