###### Securities and Exchange Commission

          - [Release No. 34-65094; File No. SR-NASDAQ-2011-11]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on August 8, 2011, The NASDAQ Stock Market LLC (“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 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 stocks contained in the Standard & Poor's 500 Index, Russell 1000 Index, and specified Exchange Traded Products that experience a price change of 10% or more during a five-minute period, so that the pilot will now expire on January 31, 2012.

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

## 4120. Trading Halts

(a) Authority to Initiate Trading Halts or Pauses

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

(1)-(10) No change.

(11) Shall, between 9:45 a.m. and 3:35 p.m., or in the case of an early scheduled close, 25 minutes before the close of trading, immediately pause trading for 5 minutes in any Nasdaq-listed security when the price of such security moves a percentage specified below within a 5-minute period.

(A) The price move shall be 10% or more with respect to securities included in the S&P 500® Index, Russell 1000® Index, and a pilot list of Exchange Traded Products;

(B) The price move shall be 30% or more with respect to all NMS stocks not subject to section (a)(i) of this Rule with a price equal to or greater than $1; and

(C) The price move shall be 50% or more with respect to all NMS stocks not subject to section (a)(i) of this Rule with a price less than $1.

The determination that the price of a stock is equal to or greater than $1 under paragraph (a)(11)(B) above or less than $1 under paragraph (a)(11)(C) above shall be based on the closing price on the previous trading day, or, if no closing price exists, the last sale reported to the Consolidated Tape on the previous trading day.

At the end of the trading pause, Nasdaq will re-open the security using the Halt Cross process set forth in Nasdaq Rule 4753. In the event of a significant imbalance at the end of a trading pause, Nasdaq may delay the re-opening of a security.

Nasdaq will issue a notification if it cannot resume trading for a reason other than a significant imbalance.

Price moves under this paragraph will be calculated by changes in each consolidated last-sale price disseminated by a network processor over a five minute rolling period measured continuously. Only regular way in-sequence transactions qualify for use in calculations of price moves. Nasdaq can exclude a transaction price from use if it concludes that the transaction price resulted from an erroneous trade.

                    If a trading pause is triggered under this paragraph, Nasdaq shall immediately notify the single plan processor responsible for consolidation of information for the security pursuant to Rule 603 of Regulation NMS under the Securities Exchange Act of 1934. If a primary listing market issues an individual stock trading pause, Nasdaq will pause trading in that security until trading has resumed on the primary listing market or notice has been received from the primary listing market that trading may resume. If the primary listing market does not reopen within 10 minutes of notification of a trading pause, Nasdaq may resume trading the security.                          ( print page 50780)    

                    The provisions of this paragraph shall be in effect during a pilot set to end on [the earlier of ]                    *January 31, 2012*                    [August 11, 2011 or the date on which a limit up/limit down mechanism to address extraordinary market volatility, if adopted, applies].

## 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 aspects 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, for a proposed rule change submitted by the Exchange, together with related rule changes 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, 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.[3]                                          The rules require the Listing Markets [4]                                          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 the Russell 1000® Index and specified Exchange Traded Products.[5]                                          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.[6]                                          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.[7]                                          On June 23, 2011, the Commission approved the expansion of the pilot to all NMS stocks, but with different pause-triggering thresholds.[8] 

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.

Accordingly, the Exchange is filing to further extend the pilot program until January 31, 2012 and remove language from the rule concerning the “limit up/limit down” mechanism.

#### 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”),[9]                                          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) [10]                                          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 [11]                                          and Rule 19b-4(f)(6) thereunder.[12]                                          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 [13]                                          and Rule 19b-4(f)(6)(iii) thereunder.[14] 

                    A proposed rule change filed under Rule 19b-4(f)(6) [15]                                          normally does not become operative for 30 days after the date of filing. However, pursuant to Rule 19b-4(f)(6)(iii) [16]                                          the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The                           ( print page 50781)                        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 as operative upon filing.[17] 

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.
