The Commission is publishing this notice to solicit comments 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 the pilot period of the trading pause for individual NMS stocks other than rights and warrants, so that the pilot will now expire on July 31, 2012.

The text of the proposed rule change is below. Proposed new language is italicized; proposed deletions are in brackets.

Rule 3100. Trading Halts on PSX

(a) Authority to Initiate Trading Halts or Pauses

In circumstances in which the Exchange deems it necessary to protect investors and the public interest, and pursuant to the procedures set forth in paragraph (c):

(1)-(3) No change.

(4) If a primary listing market issues an individual stock trading pause in any of the Circuit Breaker Securities, as defined herein, the Exchange will pause trading in that security until trading has resumed on the primary listing market. If, however, trading has not resumed on the primary listing market and ten minutes have passed since the individual stock trading pause message has been received from the responsible single plan processor, the Exchange may resume trading in such stock. The provisions of this paragraph (a)(4) shall be in effect during a pilot set to end on July 31, 2012 [January 31, 2012]. During the pilot, the term “Circuit Breaker Securities” shall mean any NMS stock except rights and warrants.

(b)-(c) No change.

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 the Statutory Basis for, the Proposed Rule Change

1. Purpose

On June 10, 2010, the Commission granted accelerated approval, for a pilot period to end December 10, 2010, of proposed rule changes submitted by the of the BATS Exchange, Inc., NASDAQ OMX BX, Inc., Chicago Board Options Exchange, Incorporated, Chicago Stock Exchange, Inc., EDGA Exchange, Inc., EDGX Exchange, Inc., International Securities Exchange LLC, The NASDAQ Stock Market LLC (“NASDAQ”), New York Stock Exchange LLC (“NYSE”), NYSE Amex LLC (“NYSE Amex”), NYSE Arca, Inc. (“NYSE Arca”), and National Stock Exchange, Inc. (collectively, the “Exchanges”), to pause trading during periods of extraordinary market volatility in S&P 500 stocks. The rules require the Listing Markets to issue five-minute trading pauses for individual securities for which they are the primary Listing Market if the transaction price of the security moves ten percent or more from a price in the preceding five-minute period. The Listing Markets are required to notify the other Exchanges and market participants of the imposition of a trading pause by immediately disseminating a special indicator over the consolidated tape. Under the rules, once the Listing Market issues a trading pause, the other Exchanges are required to pause trading in the security on their markets. On September 10, 2010, the Commission approved the respective rule filings of the Exchanges to expand application of the pilot to securities comprising the Russell 1000® Index and specified Exchange Traded Products.

In connection with its resumption of trading of NMS Stocks through the NASDAQ OMX PSX system, the Exchange adopted Rule 3100(a)(4) so that it could participate in the pilot program. On September 29, 2010, the Exchange amended Rule 3100(a)(4) to include stocks comprising the Russell 1000® Index and specified Exchange Traded Products. On December 7, 2010, the Exchange filed an immediately effective filing to extend the existing pilot program for four months, so that the pilot would expire on April 11, 2011. On March 31, 2011, the Exchange filed an immediately effective filing to extend the pilot period an additional four months, so that the pilot would expire on August 11, 2011 or the date on which a limit up/limit down mechanism to address extraordinary market volatility, if adopted, applies. On June 23, 2011, the Commission approved the expansion of the pilot to all NMS stocks, but with different pause-triggering thresholds. On August 8, 2011, the Exchange filed an immediately effective filing that removed language from the rule that tied the expiration of the pilot to the adoption of a limit up/limit down mechanism to address extraordinary market volatility, and further extended the pilot period, so that the pilot would expire on January 31, 2012. On November 18, 2011, the Exchange filed an immediately effective filing that excluded rights and warrants from the pilot.

The Exchange believes that the pilot program has been successful in reducing the negative impacts of sudden, unanticipated price movements in the securities covered by the pilot. The Exchange also believes that an additional extension of the pilot is warranted so that it may continue to assess whether circuit breakers are the best means to reduce the negative impacts of sudden, unanticipated price movements or whether alternative mechanisms would be more effective in achieving this goal.

2. Statutory Basis

The statutory basis for the proposed rule change is Section 6(b)(5) of the Securities Exchange Act of 1934 (the “Act”), which requires the rules of an exchange to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system and, in general, to protect investors and the public interest. The proposed rule change also is designed to support the principles of Section 11A(a)(1) of the Act in that it seeks to assure fair competition among brokers and dealers and among exchange markets. The Exchange believes that the proposed rule meets these requirements in that it promotes transparency and uniformity across markets concerning decisions to pause trading in a security when there are significant price movements.

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

The Exchange does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act, as amended.

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

Written comments were neither solicited nor received.

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

The Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act and Rule 19b-4(f)(6) thereunder. 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 prior to 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.

A proposed rule change filed under Rule 19b-4(f)(6) normally does not become operative for 30 days after the date of filing. However, pursuant to Rule 19b-4(f)(6)(iii) the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. 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 the 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.
