###### Securities and Exchange Commission

          - [Release No. 34-63035; File No. SR-CBOE-2010-090]

                    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 September 29, 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 filed 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 proposes for the CBOE Stock Exchange (“CBSX”) to modify its CBSX Extended Trading Hours to permit trading to open at 7:30 a.m. Central Time and continue until 3:45 p.m. Central Time. The text of the proposed rule change is available on the Exchange's Web site (                    *http://www.cboe.org/​legal*), at the Exchange's principal office, 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 CBOE 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

                    Currently, CBSX is open for trading from 8 a.m. until 3:30 p.m. (all times Central unless otherwise denoted), with the time period from 8:30 a.m. until 3 p.m. designated as CBSX Regular Trading Hours and the time periods from 8 a.m. until 8:30 a.m. and 3 p.m. until 3:30 p.m. designated as CBSX Extended Trading Hours. The Exchange has, in the past, made similar changes to extend CBSX trading hours.[5]                                          CBSX proposes to extend its hours of business to open for trading at 7:30 a.m. and close trading at 3:45 p.m. This change would not affect CBSX Regular Trading Hours; the new trading periods (7:30 a.m. until 8 a.m. and 3:30 p.m. until 3:45 p.m.) would merely extend the CBSX Extended Trading Hours.                

The Exchange represents that the modified opening and closing times will have no implications for CBSX systems. The Exchange represents that CBSX traders will have been notified of the time change via circular prior to the rule change taking effect. Lastly, the Exchange represents that appropriate surveillance will be in place for the new trading hours.

#### 2. Statutory Basis

                    The Exchange believes the proposed rule change is consistent with the Act [6]                                          and the rules and regulations thereunder and, in particular, the requirements of Section 6(b) of the Act.[7]                                          Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) [8]                                          requirements that the rules of an exchange be designed to promote just and equitable principles of trade, to prevent fraudulent and manipulative acts, to remove impediments to and to perfect the mechanism for a free and open market and a national market system, and, in general, to protect investors and the public interest. Permitting trading earlier in the morning and until later in the day will permit investors greater opportunity to participate in the market, thereby removing an impediment to trading.                

### 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 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 rule does not (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) 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, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [9]                                          and Rule 19b-4(f)(6) thereunder.[10] 

                    The Exchange has requested that the Commission 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 because such waiver will permit market participants to trade on CBSX in extended trading hours that are available on other exchanges.[11]                                          Accordingly, the Commission designates the proposed rule change operative upon filing with the Commission.[12] 

                    At any time within 60 days of the filing of the proposed rule change, the                           ( print page 62615)                        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

Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act. Comments may be submitted by any of the following methods:
