NEW YORK, Nov 4 (Reuters) – The U.S. Securities and Exchange Commission is considering whether the growth of high-frequency trading has made markets more or less efficient for long-term investors, including those trading small- and mid-cap stocks, an SEC official said on Wednesday.
US SEC seeks to curb “naked access,” expose fast trades
By Elinor Comlay
NEW YORK, Oct 27 (Reuters) – The top U.S. securities regulator said she was looking for ways to crack down on “naked access,” the practice of brokers giving high-frequency traders unfettered access to public markets.
Securities and Exchange Commission Chairman Mary Schapiro said on Tuesday that she had concerns with sponsored naked access, where brokerages that have been approved to trade on an exchange rent their access to clients who are able to shave milliseconds from the time it takes to access the markets.
