State securities regulators on Tuesday urged Congress to investigate the practice of using powerful computers to trade rapidly large volumes of securities. The practice, known as high-frequency trading (HFT), can put retail investors at a disadvantage since they generally do not have access to the same information and often buy and sell at less favorable prices, according to the North American Securities Administrators Association (NASAA). NASAA, a Washington-based organization of state securities regulators, made its appeal during a news conference at the National Press Club in the U.S. capital. More on Reuters here.
