SEC Conducts Review of Equity Market Structure

The Securities and Exchange Commission is conducting a broad review of the current equity market structure. The review includes an evaluation of equity market structure performance in recent years and an assessment of whether market structure rules have kept pace with, among other things, changes in trading technology and practices. To help further its review, the Commission invites public comment on a wide range of market structure issues, including high frequency trading, order routing, market data linkages, and undisplayed, or "dark," liquidity. The Commission intends to use the public’s comments to help determine whether regulatory initiatives to improve the current equity market structure are needed and, if so, the specific nature of such initiatives.
