Self-Regulatory Organizations; The NASDAQ Stock Market LLC; Order Instituting Proceedings To Determine Whether To Disapprove Proposed Rule Change, as Modified by Amendment No. 1, To Adopt Rule 4753(c) as a Six Month Pilot in 100 NASDAQ-Listed Securities

I. Introduction

On June 18, 2010, The NASDAQ Stock Market LLC (“Nasdaq” or the “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, a proposed rule change to implement, on a six-month pilot basis, a volatility-based trading pause in 100 Nasdaq-listed securities (“Volatility Guard”). On June 25, 2010, Nasdaq filed Amendment No. 1 to the proposed rule change. The proposed rule change, as amended, was published for comment in the Federal Register on July 15, 2010. The Commission received four comment letters on the proposal. Nasdaq responded to these comments on August 12, 2010. The Commission subsequently extended the time period in which to either approve the proposed rule change, or to institute proceedings to determine whether to disapprove the proposed rule change, to October 13, 2010. This order institutes proceedings to determine whether to disapprove the proposed rule change.

II. Description of the Proposal

Nasdaq proposes to adopt, on a pilot basis, a volatility-based trading halt for 100 Nasdaq-listed securities. Under this proposal, Nasdaq would suspend trading in a security if a trade in that security is executed at a price that exceeds a certain threshold, as measured over the preceding 30 seconds. The triggering threshold varies according to the price of the security, i.e., 15% for securities with an execution price of $1.75 and under; 10% for securities over $1.75 and up to $25; 5% for securities over $25 and up to $50; and 3% for securities over $50. If the Volatility Guard were triggered, Nasdaq would suspend trading in that security for a period of 60 seconds, but would maintain all current quotes and orders during that time, and would continue to accept quotes and orders. Following this 60-second period, Nasdaq would re-open the market using its Halt Cross mechanism. According to Nasdaq, the Volatility Guard is similar in purpose to the Liquidity Replenishment Points (“LRPs”) rules that currently exist on the New York Stock Exchange (“NYSE”).

III. Comment Letters

Three of the four commenters expressed concerns about the effect of this proposal upon market volatility. These commenters stated that the Volatility Guard could actually increase volatility marketwide by re-directing trading in a security to other potentially less liquid venues once trading in that security had been halted on Nasdaq. One commenter argued that this proposal, coupled with the LRPs currently in effect on the NYSE, would result in disparate market approaches towards dampening volatility that may create confusion among market participants, particularly in times of market stress, and exacerbate market volatility.

The fourth commenter, however, supported Nasdaq's “right to design the controls it believes are best for trading on its market.” This commenter stated that the national market system was designed to encourage competitive distinctions such as Nasdaq's Volatility Guard and NYSE's LRPs. According to this commenter, both the Nasdaq proposal and the NYSE LRPs “provide certainty and predictability of operation,” and permit those markets to pursue strategies where the quality of price need not always defer to speed of execution.

In its response, Nasdaq rejected the argument that the proposed Volatility Guard would exacerbate market volatility. Nasdaq stated that it specifically designed the Volatility Guard to work within the parameters of the recently adopted single-stock circuit breakers, and to avoid the potential for conflicting standards between the two mechanisms. Nasdaq also asserted that there is no evidence that the Volatility Guard would increase volatility in a particular security; rather, Nasdaq stated that the Volatility Guard would actually keep aberrant volatility on Nasdaq from spreading to other markets.

Nasdaq also argued that the proposed Volatility Guard differed significantly from the NYSE LRPs, and that criticizing the Volatility Guard by comparing it to the LRPs was misleading. Nasdaq stated that the Volatility Guard, unlike the LRPs, would be based on clear and predictable criteria that would trigger a pause only in the event of a significant imbalance. Accordingly, Nasdaq did not believe it appropriate to make a generic assertion that all market-based single-stock circuit breakers are detrimental.

Finally, Nasdaq stated that it was employing prudent precautions in implementing the Volatility Guard. In particular, Nasdaq would implement the Volatility Guard as a pilot, limited in time and scope, during which time the Volatility Guard could be adjusted as needed. Nasdaq would also provide data to the Commission during the pilot period about the efficiency and effect of the Volatility Guard.

IV. Proceedings To Determine Whether To Disapprove SR-NASDAQ-2010-074 and Grounds for Disapproval Under Consideration

Nasdaq's proposal is presented by the Exchange as an effort to protect Nasdaq-listed securities and Nasdaq market participants from aberrant volatility, such as that witnessed on May 6, 2010. As noted above, however, several commenters argued that individual exchange-specific mechanisms to moderate volatility may in fact exacerbate the volatility of the market overall, create confusion, and complicate the operation of the market-wide single stock circuit breakers.

Although the events of May 6, 2010 provide but one example of the effect of an individual exchange volatility moderator, the Report of the Staff of the Commodity Futures Trading Commission and the Commission (the “May 6 Staff Report”) did not find that NYSE LRPs caused or created the broad-based liquidity crisis on that day. However, the May 6 Staff Report noted, among other things, that there were a few LRP events affecting certain stocks in which available liquidity on the NYSE may have been sufficient to absorb some of the selling pressure felt by other markets. In addition, there were reports from market participants that the increasing number of LRPs on May 6 played into their decisions to reduce liquidity, pause trading, or withdraw from the markets. More broadly, the Commission notes that it is not yet clear whether the market-wide single-stock circuit breakers, as they may be expanded or adjusted, are likely to interact with individual exchange volatility moderators such as the NYSE LRPs or, if approved, Nasdaq's Volatility Guard, in a positive, neutral or negative way.

The Commission, therefore, is instituting proceedings pursuant to Section 19(b)(2)(B) of the Act to determine whether the proposed rule change should be disapproved. Institution of disapproval proceedings appears appropriate at this time in view of the legal and policy issues raised by the proposal. Institution of disapproval proceedings, however, does not indicate that the Commission has formulated any conclusions with respect to any of the issues involved. Rather, as described in greater detail below, the Commission seeks and encourages interested persons to comment on the proposed rule change.

The section of the Act applicable to the proposed rule change that provides the grounds for disapproval under consideration is Section 6(b)(5), which requires that the rules of an exchange be designed, among other things, to prevent fraudulent and manipulative acts and practices, 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. Specifically, the Commission believes the proposal raises issues as to whether the Volatility Guard, by halting trading on Nasdaq when the price of a security moves quickly over a short period of time, will exacerbate the volatility of trading in that security on the other exchanges and over-the-counter trading centers that remain open. In addition, because the thresholds for triggering the Volatility Guard, and the length of the trading halt that results, differ from those of the recently approved, market-wide single-stock circuit breakers, the Commission believes the proposal raises issues as to whether the operation of the Volatility Guard will interfere with, or otherwise limit the effectiveness of, the circuit breakers, the goal of which is to prevent potentially destabilizing price volatility across the U.S. securities markets.

V. Procedure: Request for Written Comments

The Commission requests that interested persons provide written submissions of their views, data and arguments with respect to the concerns identified above, as well as any others they may have with the proposal. In particular, the Commission invites the written views of interested persons concerning whether the proposed rule change is inconsistent with the Section 6(b)(5) or any other provision of the Act, or the rules and regulations thereunder. Although there do not appear to be any issues relevant to approval or disapproval which would be facilitated by an oral presentation of views, data, and arguments, the Commission will consider, pursuant to Rule 19b-4, any request for an opportunity to make an oral presentation.

Interested persons are invited to submit written data, views and arguments regarding whether the proposed rule change should be disapproved by December 3, 2010. Any person who wishes to file a rebuttal to any other person's submission must file that rebuttal by December 20, 2010.

The Commission specifically reiterates its request for comment on the following items:

• A stated purpose of the proposal is to protect Nasdaq-listed securities and market participants from “aberrant” volatility, such as that which occurred on May 6, 2010 and may be caused by operational or structural factors beyond the control of issuers and individual markets. To what extent do the price changes that would trigger a trading halt under the proposal indicate the potential existence of “aberrant” volatility, as opposed to the normal operation of the markets? If these price changes indicate potentially “aberrant” volatility, to what extent will the proposal address such volatility in a manner appropriate and consistent with the purposes of the Act?
• Will a trading halt at Nasdaq under the proposal restrict liquidity or increase volatility in the affected stock, since other markets can continue to trade the stock and may not have comparable volatility halts?
• In what respects are the consequences of this proposal likely to be similar to, or different from, the effects of other exchange-specific mechanisms that currently restrict trading on the relevant exchange under certain circumstances?
• More generally, to what extent is it appropriate for the various exchanges to adopt different and potentially inconsistent approaches to trading pauses or restrictions that might affect the same stock?
• To what extent does the answer change based on whether the affected stock is already subject to a market-wide single-stock circuit breaker that applies consistently across all trading venues?
