###### Securities and Exchange Commission

          - [Release No. 34-62124; File No. SR-BX-2010-037]

                    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 May 18, 2010, NASDAQ OMX BX, Inc. (the “Exchange” or “BX”) 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.

## 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 Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

The primary listing markets for U.S. stocks are in the process of amending their rules so that they may, from time to time, issue a trading pause for an individual security if the price of such security moves 10% or more from a sale in a preceding five-minute period. The Exchange is proposing the rule change described below in consultation with other markets and Commission staff to provide for uniform market-wide trading pause standards for individual securities in the S&P 500 ® Index, as set forth below. The Exchange is not currently the primary listing market for any securities, and thus, will not be issuing any trading pauses pursuant to its rules.

The Exchange proposes to add a new paragraph to BX Rule 4120(a) to allow the Exchange to pause trading in an individual stock when the primary listing market for such stock issues a trading pause in any Circuit Breaker Securities, as defined below and in proposed IM-4120-3. 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 proposed rule would apply to trading pauses issued by primary listing markets in “Circuit Breaker Securities,” as defined in proposed IM-4120-3. Specifically, on a pilot basis, set to end on December 10, 2010, Circuit Breaker Securities would mean the securities included in the S&P 500 ® Index. Thus, proposed paragraph (11) of the Rule would be in effect only with respect to securities in the S&P 500 ® Index.

#### 2. Statutory Basis

                    The Exchange believes that the proposed rule change is consistent with the provisions of Section 6 of the Act,[4]                                          in general, and with Sections 6(b)(5) of the Act,[5]                                          in particular, in that the proposal is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, 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 is also designed to support the principles of Section 11A(a)(1) [6]                                          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

                    Within 35 days of the date of publication of this notice in the                     **Federal Register**                     or within such longer period (i) as the Commission may designate up to 90 days of such date if it finds such longer period to be appropriate and publishes its reasons for so finding or (ii) as to which the self-regulatory organization consents, the Commission will:                

(A) By order approve the proposed rule change, or

                    (B) Institute proceedings to determine whether the proposed rule change should be disapproved.[7]
