Self-Regulatory Organizations; National Stock Exchange, Inc.; Notice of Filing and Immediate Effectiveness of Proposed Rule Change To Amend Rule 11.19 To Extend Pilot Program Regarding Clearly Erroneous Executions

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”) and Rule 19b-4 thereunder, notice is hereby given that on September 30, 2013, National Stock Exchange, Inc. (“NSX®” or the “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change, as described in Items I and II below, which Items have been prepared by the Exchange. The Commission is publishing this notice to solicit comment on the proposed rule change from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

The Exchange proposes to extend a pilot program related to Rule 11.19, entitled “Clearly Erroneous Executions.” The Exchange also proposes to remove certain references to individual stock trading pauses contained in Rule 11.19(c)(4) and to amend to Rule 11.19 to make technical and non-substantive changes in the rule text. The Exchange has designated this proposal as non-controversial and provided the Commission with the notice required by Rule 19b-4(f)(6)(iii) under the Act.

The text of the proposed rule change is available on the Exchange's Web site at http://www.nsx.com,, at the principal office of the Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The purpose of this filing is to extend the effectiveness of the Exchange's current rule applicable to Clearly Erroneous Executions and to remove references to individual stock trading pauses described in Rule 11.19(c)(4). Portions of Rule 11.19, explained in further detail below, are currently operating as a pilot program set to expire on September 30, 2013. The Exchange proposes to extend the pilot program to April 8, 2014.

On September 10, 2010, the Commission approved, on a pilot basis, changes to NSX Rule 11.19 to provide for uniform treatment: (1) Of clearly erroneous execution reviews in multi-stock events involving twenty or more securities; and (2) in the event transactions occur that result in the issuance of an individual stock trading pause by the primary listing market and subsequent transactions that occur before the trading pause is in effect on the Exchange. The Exchange also adopted changes to Rule 11.19 that reduced the ability of the Exchange to deviate from the objective standards set forth in Rule 11.19 and, in 2013, adopted a provision designed to address the operation of the Plan to Address Extraordinary Market Volatility Pursuant to Rule 608 of Regulation NMS under the Act (the “Limit Up-Limit Down Plan” or the “Plan”). The Exchange believes the benefits to market participants from the more objective clearly erroneous executions rule should continue on a pilot basis through April 8, 2014, which is one year following the commencement of operations of the Plan. The Exchange believes that continuing the pilot during this time will protect against any unanticipated consequences. Thus, the Exchange believes that the protections of the Clearly Erroneous Rule should continue while the industry gains further experience operating the Limit Up-Limit Down Plan.

The Exchange also proposes to eliminate all references in Rule 11.19 to individual stock trading pauses issued by a primary listing market. Specifically, Rule 11.19(c)(4) provides specific rules to follow with respect to review of an execution as potentially clearly erroneous when there was an individual stock trading pause issued for that security and the security is included in the S&P 500® Index, the Russell 1000® Index, or a pilot list of Exchange Traded Products (“Circuit Breaker Securities”). The stock trading pauses described in Rule 11.19(c)(4) are being phased out as securities become subject to the Plan pursuant to a phased implementation schedule. The Plan is already operational with respect to all Circuit Breaker Securities and thus the Exchange believes that all references to individual stock trading pauses should be removed, including all cross-references to Rule 11.19(c)(4) contained in other portions of Rule 11.19.

Finally, the Exchange is proposing amendments to Rule 11.19 to make technical and non-substantive changes in the rule text. These changes include removing incorrect references in the first paragraph of the rule to paragraph (i) when the correct reference should be to paragraph (j), and correcting certain other language and punctuation issues.

2. Statutory Basis

The Exchange believes that its proposal is consistent with the requirements of the Act and the rules and regulations thereunder that are applicable to a national securities exchange and, in particular, with the requirements of Section 6(b) of the Act. In particular, the proposal is consistent with Section 6(b)(5) of the Act, because it would promote just and equitable principles of trade and remove impediments to, and perfect the mechanism of, a free and open market and a national market system. The Exchange believes that the pilot program promotes just and equitable principles of trade in that it promotes transparency and uniformity across markets concerning review of transactions as clearly erroneous. More specifically, the Exchange believes that the extension of the pilot would help assure that the determination of whether a clearly erroneous trade has occurred will be based on clear and objective criteria, and that the resolution of the incident will occur promptly through a transparent process. The proposed rule change would also help assure consistent results in handling erroneous trades across the U.S. markets, thus furthering fair and orderly markets, the protection of investors and the public interest. Although the Plan will become fully operational during the same time period as the proposed extended pilot, the Exchange believes that maintaining the pilot will help to protect against unanticipated consequences. To that end, the extension will allow the Exchange to determine whether Rule 11.19 is necessary once the Plan is fully operational and, if so, whether improvements can be made. The elimination of references to individual stock trading pauses will help to avoid confusion among market participants, which is consistent with the protection of investors and the public interest and therefore consistent with the Act. As described above, individual stock trading pauses have been replaced by the Plan with respect to all Circuit Breaker Securities.

With respect to the technical, non-substantive changes to the text of Rule 11.19, the Exchange believes that these are consistent with Section 6(b)(5) of the Act in that they correct certain incorrect references to other section of the rule text and other language and punctuation items, thereby enhancing the clarity of Exchange rules, which is consistent with promoting just and equitable principles of trade and the protection of investors and the public interest.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change implicates any competitive issues. To the contrary, the Exchange believes that the Financial Industry Regulatory Authority, Inc. (“FINRA”) and other national securities exchanges are also filing similar proposals, and thus, that the proposal will help to ensure consistent rules across market centers.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants or Others

Written comments on the proposed rule change were neither solicited nor received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

Because the proposed rule change does not (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder.

The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest, as it will allow the pilot program to continue uninterrupted, thereby avoiding investor confusion that could result from a temporary interruption in the pilot program. For this reason, the Commission designates the proposed rule change to be operative upon filing.

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act.
