###### Securities and Exchange Commission

          - [Release No. 34-63512; File No. SR-NSX-2010-17]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]                                          and Rule 19b-4 [2]                                          thereunder, notice is hereby given that on December 7, 2010, National Stock Exchange, Inc. (“NSX” or “Exchange”) filed with the Securities and Exchange Commission (the “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

National Stock Exchange, Inc. (“NSX®” or “Exchange”) is proposing to amend its rules to extend until April 11, 2011, a certain pilot program regarding trading pauses in individual securities due to extraordinary market volatility.

                    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

With this rule change, the Exchange is proposing to extend a pilot program currently in effect regarding trading pauses in individual securities due to extraordinary market volatility under NSX Rule 11.20B. Currently, unless otherwise extended or approved permanently, this pilot program will expire on December 10, 2010. The instant rule filing proposes to extend the pilot program until April 11, 2011.

                    NSX Rule 11.20B (Trading Pauses in Individual Securities Due to Extraordinary Market Volatility) was approved by the Securities and Exchange Commission (the “Commission”) on June 10, 2010 on a pilot basis to end on December 10, 2010.[3]                                          Similar rule changes were adopted by other markets in the national market system in a coordinated manner. As the Exchange noted in its filing to adopt NSX Rule 11.20B, during the pilot period, the Exchange, in conjunction with other markets in the national market system, would continue to assess whether additional securities need to be added and whether the parameters of the rule would need to be modified to accommodate trading characteristics of different securities. NSX Rule 11.20B was expanded to include additional exchange traded products on September 10, 2010.[4]                                          The Exchange, in consultation with the Commission and other markets, has determined that the duration of this pilot program should be extended. Accordingly, pursuant to the instant rule filing, the expiration date of the pilot program referenced in Commentary .05 to Rule 11.20B is proposed to be changed from “December 10, 2010” to “April 11, 2011.”                

#### 2. Statutory Basis

                    The Exchange believes that the proposed rule change is consistent with the provisions of Section 6(b) and Section 11A of the Act,[5]                                          in general, and Section 6(b)(5) of the Act,[6]                                          in particular, in that it is designed, among other things, to promote clarity, transparency and full disclosure, in so doing, to prevent fraudulent and manipulative acts and practices, to promote just and                           ( print page 78787)                        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. Moreover, the proposed rule change is not discriminatory in that it uniformly applies to all ETP Holders.                

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

The Exchange does not believe that the proposed rule change will impose any inappropriate burden on competition.

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

The Exchange has neither solicited nor received written comments on the proposed rule change.

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

                    Because the foregoing proposed rule change does not: (1) Significantly affect the protection of investors or the public interest; (2) impose any significant burden on competition; and (3) 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, it has become effective pursuant to Section 19(b)(3)(A) of the Act [7]                                          and Rule 19b-4(f)(6) thereunder.[8] 

                    A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing.[9]                                          However, Rule 19b-4(f)(6) [10]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay.                

                    The Commission has considered the Exchange's request to waive the 30-day operative delay. 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.[11]                                          Therefore, 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. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule change should be approved or disapproved.
