SEC considers introducing new curbs on high frequency trading

US SECURITIES regulators are deciding whether rules are needed to curb high-frequency traders, whose lightning-fast computer programmes now dominate equities markets.

In a move that could overhaul how markets function, the Securities and Exchange Commission voted yesterday to seek public comment on the rapid trades, the anonymous trading venues known as dark pools, and other market developments that have blossomed over the last decade.

The SEC will publish a so-called concept release asking whether the current structure of markets is fair to investors and whether they have the tools to protect their interests.

“We must continually assess how changes in the market are affecting investors.” said SEC chairman Mary Schapiro.
