On October 14th, SEC Chairman Mary Schapiro and Martin Wheatley, Managing Director of the Conduct Business Unit at the U.K. Financial Services Authority, co-hosted a meeting among regulators from Europe, the Americas, Asia, and Australia to share views on issues pertaining to equity market structure. The roundtable considered how advances in technology, new trading strategies, and the increasing integration and globalization of markets have impacted developments in equity market structure. Specifically, the leaders of the various regulatory agencies shared their views on issues related to automated trading strategies, such as high frequency trading, market fragmentation, and undisplayed liquidity (for example, "dark pools"). The participants also discussed possible approaches that regulators might adopt in the light of these market structure developments. The discussion highlighted the need for global coordination on regulatory approaches to many of these issues. SEC Press Release.
