Jul 31: Joe Saluzzi on regulators and trading

Joe Saluzzi, co-head of equity trading at Themis Trading, an institutional agency brokerage firm, welcomes the announcement that the SEC will start investigating flash orders. "I don't like excess regulation, however, when there's a situation which is built to favour a class of investor which represents 2 per cent of the actual traders but controls 70 per cent of the volume, we may have to have somebody else here to look at it."
