January 30, 2012.
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 January 23, 2012, the Chicago Stock Exchange, Inc. (“CHX” 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 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
CHX proposes to amend its rules to extend the pilot program relating to individual securities circuit breakers. The text of this proposed rule change is available on the Exchange's Web site at (www.chx.com) and in 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
In June, 2010, CHX obtained Commission approval to amend Article 20, Rule 2 to create circuit breakers in individual securities on a pilot basis to end on December 10, 2010.
Shortly thereafter, in September, the Commission approved another amendment to Article 20, Rule 2 to add securities included in the Russell 1000® Index (“Russell 1000”) and certain specified Exchange Traded Products (“ETP”) to the pilot rule.
This program was subsequently extended until April 11, 2011 
and was again extended until August 11, 2011.
Then, in June, 2011, the Commission approved another amendment to Article 20, Rule 2 to add all NMS stocks to the pilot rule 
and, subsequently, the pilot was extended to January 31, 2012.
The proposed rule change merely extends the duration of the pilot program to July 31, 2012. Extending the pilot in this manner will allow the Commission more time to consider the impact of the pilot program.
2. Statutory Basis
The proposed rule change is consistent with 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 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 impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.
C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others
No written comments were either solicited or 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.
IV. Solicitation of Comments
