Self-Regulatory Organizations; Miami International Securities Exchange LLC; Notice of Filing and Immediate Effectiveness of a Proposed Rule Change To Amend Exchange Rules 307 and 309 To Extend the SPY Pilot Program

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 June 10, 2016, Miami International Securities Exchange LLC (“MIAX” 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 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 the Substance of the Proposed Rule Change

The Exchange is filing a proposal to amend Exchange Rules 307 and 309 to extend the pilot program that eliminates the position and exercise limits for physically-settled options on the SPDR® S&P 500® ETF Trust (“SPY Pilot Program”) and to make non-substantive technical corrections to Interpretations and Policies .01.

The text of the proposed rule change is available on the Exchange's Web site at http://www.miaxoptions.com/filter/wotitle/rule_filing,, at MIAX'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 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

Exchange Rules 307, Position Limits, and 309, Exercise Limits, establish position and exercise limits for aggregate positions in option contracts traded on the Exchange. Interpretations and Policies .01 to Rule 307 lists specific position limits for options on specific underlying securities, and Interpretations and Policies .01 to Rule 309 lists specific exercise limits for options on specific underlying securities. Among the listed specific underlying securities is the SPDR® S&P 500® ETF Trust (“SPY”). Currently, each of these Rules provides that there is no position limit and no exercise limit on options overlying SPY. The position and exercise limits for options overlying SPY in each of these Rules are the subject of a pilot program, which is scheduled to expire on July 12, 2016.

The Exchange proposes to amend Exchange Rule 307, Interpretations and Policies .01, and Exchange Rule 309, Interpretations and Policies .01, to extend the duration of the SPY Pilot Program through July 12, 2017. There are no substantive changes being proposed to the SPY Pilot Program. The Exchange affirms its consideration of several factors that support the proposal to establish and extend the SPY Pilot Program, which include: (1) The liquidity of the option and the underlying security; (2) the market capitalization of the underlying security and the securities that make up the S&P 500 Index; (3) options reporting requirements; and (4) financial requirements imposed by MIAX and the Commission.

The Exchange notes that it is not aware of any problems created by the current SPY Pilot Program and does not foresee any problems with the proposed extension. The Exchange has formally submitted a Report for the SPY Pilot Program as part of this filing. In addition, the Exchange represents that if it chooses to extend or seek permanent approval of the SPY Pilot Program, the Exchange will submit another SPY Pilot Program Report at least thirty (30) days prior to the expiration of the extended SPY Pilot Program time period which would cover the period between reports. The SPY Pilot Program Report will compare the impact of the pilot program, if any, on the volumes of SPY options and the volatility in the price of the underlying SPY contract, particularly at expiration. The SPY Pilot Program Report will also detail the size and different types of strategies employed with respect to positions established in SPY options; note whether any problems, in the underlying SPY ETF or otherwise, arose as a result of the no-limit approach; and include any other information that may be useful in evaluating the effectiveness of the SPY Pilot Program. In preparing the Pilot Report, the Exchange will utilize various data elements such as volume and open interest. In addition the Exchange would make available to Commission staff data elements relating to the effectiveness of the SPY Pilot Program.

The Exchange proposes to extend the SPY Pilot Program in order for the Exchange and the Commission to have additional time to evaluate the Pilot and its effect on the market and to determine whether to seek permanent approval. Prior to the expiration of the SPY Pilot Program and based upon the findings of the SPY Pilot Program Report, the Exchange will be able to either extend the SPY Pilot Program, adopt the SPY Pilot Program on a permanent basis, or terminate the SPY Pilot Program. If the SPY Pilot Program is not extended or adopted on a permanent basis by the expiration of the extended SPY Pilot Program, the position limits for options overlying SPY would revert to limits in effect prior to the commencement of the SPY Pilot Program.

Additionally, the Exchange proposes to make non-substantive technical changes to the chart of securities in Interpretations and Policies .01 of both Rule 307 and 309 to reflect the current names of the underlying securities identified in the chart.

2. Statutory Basis

MIAX believes that its proposed rule change is consistent with Section 6(b) of the Act in general, and furthers the objectives of Section 6(b)(5) of the Act in particular, in that it 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 facilitating transactions in securities, to remove impediments to and perfect the mechanisms of a free and open market and a national market system and, in general, to protect investors and the public interest.

Specifically, the Exchange believes that extending the SPY Pilot Program promotes just and equitable principles of trade by permitting market participants, including market makers, institutional investors and retail investors, to establish greater positions when pursuing their investment goals and needs. The Exchange believes that the elimination of position limits for SPY options would not increase market volatility or facilitate the ability to manipulate the market.

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. The proposed rule change is not designed to address any aspect of competition, whether between the Exchange and its competitors, or among market participants. Instead, the proposed rule change is designed to allow the SPY Pilot Program to continue as the Exchange believes other competing options exchanges will also extend the SPY Pilot Program for another year.

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

Because the foregoing 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 for 30 days after the date of the filing, or such shorter time as the Commission may designate, it has become effective pursuant to 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

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. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
