October 12, 2007.

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 March 21, 2007, the Chicago Stock Exchange, Inc. (“CHX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been substantially prepared by CHX. 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 amend its rules to add new provisions to confirm how institutional brokers should handle stop and stop-limit orders. The text of the proposed rule change is available at http://www.chx.com/​rules/​proposed_​rules.htm, at 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 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 Exchange proposes to add a new provision to its institutional broker rules to confirm how institutional brokers should handle stop and stop-limit orders.^[3] Under these provisions, an institutional broker could choose to, but would not be required to, accept stop or stop-limit orders.

Under this proposal, a stop order to buy (sell) would become a market order when a transaction in the security at or above (below) the stop price is reported in an effective transaction reporting plan after the order is received by an institutional broker. Similarly, stop-limit orders to buy (sell) would become limit orders when a transaction in the security at or above (below) the stop price is reported in an effective transaction reporting plan after the order is received by an institutional broker. Stop or stop-limit orders could be elected either by the price of the opening transaction on the Exchange or by the price of the opening on any other market center reporting in an effective transaction reporting plan. These proposed provisions are substantially similar to requirements set forth in the rules of other self-regulatory organizations, including New York Stock Exchange LLC (“NYSE”) and the Financial Industry Regulatory Authority, Inc. (“FINRA”) (f/k/a National Association of Securities Dealers, Inc. (“NASD”)).^[4]

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act ^[5] in general, and furthers the objectives of Section 6(b)(5) of the Act.^[6] The proposed rule change is consistent with Section 6(b)(5) of the Act because it would promote just and equitable principles of trade, remove impediments to and perfect the mechanism of, a free and open market and a national market system, and, in general, protect investors and the public interest by permitting the Exchange to add a new provision to its institutional broker rules to confirm how institutional brokers should handle stop and stop-limit orders.

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.

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

Written comments on the proposed rule change 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 Exchange consents, the Commission will:

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

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