Mary L. Schapiro: “Investor protection is the foundation upon which all our responsibilities are built.”

I believe we need a deeper understanding of the strategies and activities of high-frequency markets and traders and the potential impact on our markets and investors of so many transactions occurring so quickly.

I commend Congressman Westmoreland and Ranking Member Frank for bringing forward bipartisan legislation, H.R. 3503, to bring transparency to the PCAOB's disciplinary proceedings.

A stable, fair, and efficient market structure is the backbone of the equity markets and an important engine of our economy.

These are critically important goals, and I support robust implementation of the Dodd-Frank Act's whistleblower program to support Congressional intent.
