Market Structure Roundtable

The Securities and Exchange Commission will host a one-day roundtable to solicit the views of investors, issuers, exchanges, alternative trading systems, financial services firms, high frequency traders, and the academic community regarding the current securities market structure. The roundtable will focus on market structure performance, including the events of May 6, metrics for evaluating market structure performance, high frequency trading, and undisplayed liquidity. The roundtable discussion will be held in the auditorium of the Securities and Exchange Commission headquarters at 100 F Street, NE., in Washington, DC on June 2, 2010 from 9:30 a.m. to approximately 4:30 p.m. The public is invited to observe the roundtable discussion. Seating will be available on a first-come, first-served basis. The roundtable discussion also will be available via webcast on the Commission's Web site at http://www.sec.gov. The roundtable will consist of a series of panels. Panelists will consider a range of market structure topics, such as the appropriate metrics for assessing the performance and fairness of the market structure, particularly in light of the extraordinary price volatility of May 6. Panelists also will analyze the tools and strategies of high frequency trading and the role of undisplayed liquidity in today's market structure.
