###### Securities and Exchange Commission

          - [Release No. 34-63235; File No. SR-CBOE-2010-099]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on October 26, 2010, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) 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 Exchange has designated the proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act [3]                                          and Rule 19b-4(f)(6) thereunder.[4]                                          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 is proposing to amend CBOE Stock Exchange, LLC's (“CBSX,” the CBOE's stock trading facility) rules to describe the manner in which the CBSX System [5]                                          will handle short sell orders in relation to Rule 201 of Regulation SHO,[6]                                          and CBOE's rules to include order marking requirements for stock-option orders. The text of the proposed rule change is available on the Exchange's Web site (                    *http://www.cboe.org/​Legal*                     ), at the Exchange's Office of the Secretary and at the Commission.                

## 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 those 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 the Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

                    Rule 201 of Regulation SHO under the Act [7]                                          sets forth a short sale-related circuit breaker that, if triggered, will impose a restriction on the prices at which NMS stocks [8]                                          may be sold short. In anticipation of the upcoming November 10, 2010 compliance date for Rule 201,[9]                                          the Exchange is proposing to amend CBSX's rules to describe the manner in which the CBSX System will handle short sell orders when a circuit breaker is triggered under Rule 201 of Regulation SHO.                

                    In particular, the Exchange is proposing to adopt Interpretation and Policy .02 to its Rule 51.8,                     *Types of Orders Handled,*                     to provide that orders in equity securities that are submitted to the CBSX System must be marked “long,” “short,” or “short exempt” in compliance with Regulation SHO.[10]                                          The Interpretation and Policy will also provide that, if a short sale-related circuit breaker is triggered under Regulation SHO, orders marked “short” will be handled by the CBSX System as follows: First, short sell orders that are resting in the CBSX Book [11]                                          at the time a circuit breaker is triggered will be permitted to continue resting and/or execute. The Exchange believes this handling of resting short sell orders is consistent with Rule 201 because resting orders by definition are priced above the National Best Bid.[12]                                          Second, short sell orders that are received by the CBSX System after the time a circuit breaker is triggered that are priced above the National Best Bid will be permitted to rest and/or execute. The Exchange believes this handling of incoming short sell orders is consistent with Rule 201 because the orders are priced above the National Best Bid.[13]                                          Third, short sell orders that are received by the CBSX System after the time a circuit breaker is triggered that are priced at or below                           ( print page 68843)                        the National Best Bid will be rejected/cancelled by the CBSX System. The Exchange believes this handling of incoming short sell orders is consistent with Rule 201 because the orders are not priced above the National Best Bid.[14] 

                    The Exchange notes that, under these procedures, a reserve sell order [15]                                          that is marked “short” will be handled the same as any other sell order marked “short.” Thus, an incoming reserve sell order that is received by the CBSX System after the time a circuit breaker is triggered that is marked “short” and that is priced at or below the National Best Bid will be rejected/cancelled by the CBSX System. An incoming reserve sell order that is received by the CBSX System after the time a circuit breaker is triggered that is marked “short” and that is priced above the National Best Bid will be permitted to rest and/or execute. The Exchange also notes that the entire size of a reserve sell order that is marked “short” and resting in the CBSX Book—both the displayed portion and the reserve portion at the same price that is not displayed—will be permitted to rest and/or execute. This handling will apply to reserve orders resting in the CBSX Book at the time a circuit breaker is triggered or to incoming reserve orders that rest in the CBSX Book after a circuit breaker is triggered. The Exchange believes this handling of reserve orders marked “short” is consistent with Rule 201 because resting reserve orders that are marked “short” by definition are priced above the National Best Bid at the time of initial display.[16] 

                    Sell orders marked “short exempt” will be permitted to rest and/or execute without regard to when the order is received or whether the order is priced above, at or below the National Best Bid. This handling of sell orders marked “short exempt” would be applied by the CBSX System at all times—without regard to whether a circuit breaker is triggered. The Exchange believes this handling by CBSX of sell orders marked “short exempt” is consistent with Rule 201, which permits the execution or display of a short sell order in an NMS stock marked “short exempt” without regard to whether the order is at a price that is less than or equal to the current National Best Bid.[17] 

                    The Exchange is also proposing to amend Interpretation and Policy .06 to its Rule 6.53C,                     *Complex Orders on the Hybrid System,*                     to include an order marking requirement for stock-option orders. In particular, the Exchange is proposing to provide that, if the stock leg of a stock-option order submitted to CBOE's electronic complex order book (referred to in the rules as “COB”) [18]                                          or electronic complex order request for response auction (referred to in the rules as “COA”) [19]                                          is a sell order, then the stock leg must be marked “long, “short,” or “short exempt” in compliance with Regulation SHO.[20] 

                    Finally, the Exchange is proposing to make non-substantive technical updates to its Rule 53.5,                     *“Long” and “Short” Sales.*                     In particular, the Exchange is proposing to change the title of the rule to “                    *`Long,' `Short' and `Short Exempt' Sales”*                     and to delete an outdated reference to SEC Rule 10a-1 (which no longer exists and has been superseded by Regulation SHO).                

#### 2. Statutory Basis

                    The Exchange believes the proposed rule change is consistent with Section 6(b) of the Act,[21]                                          in general, and, in particular, furthers the objectives of Section 6(b)(5) of the Act,[22]                                          which requires that an exchange have rules that are designed to promote just and equitable principles of trade and, in general, to protect investors and the public interest. In particular, the Exchange believes the proposed change will provide clarity on the short sell order handling procedures that the CBSX System will apply when a short sale-related circuit breaker is triggered under Rule 201 of Regulation SHO in a manner that the Exchange believes is consistent with Regulation SHO.                

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

CBOE 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

The Exchange neither solicited nor received comments on the proposal.

## 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 [23]                                          and Rule 19b-4(f)(6) thereunder.[24] 

                    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.[25]                                          However, Rule 19b-4(f)(6) [26]                                          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 to allow updating of its rules before the November 10, 2010 compliance date of the amendments to Rule 200(g) and 201 of Regulation SHO [27]                                          and thereby provide clarity on the short sell order handling procedures that the CBSX System will apply when a short sale-related circuit breaker is triggered under Rule 201 of Regulation SHO. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because the waiver will provide clarity to market participants that trade on CBSX System on the handling of certain orders in light of the amendments to Regulation SHO.[28]                                          The Commission also believes that the proposed rule change does not raise any new or novel issues. Accordingly, the Commission designates the proposed rule change                           ( print page 68844)                        operative upon filing with the Commission.[29] 

At any time within 60 days of the filing of such 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.
