he SEC promised to clip traders’ wings. Mary Jo White, who heads the US securities regulator, said the agency is formulating a sweeping set of new rules to impose limits on high-frequency trading, “dark pools” and other technologies blamed for volatility in the markets.
Beyond high-speed trading, White also announced that the staff is drafting other market structure reforms.
One such rule would require alternative trading venues such as dark pools and firms that match customers’ orders internally to tell regulators and the public about how they operate.
Dark pools allow investors to execute trades anonymously and only make trading data available afterwards.
Another proposal would seek to mitigate potential conflicts of interest at brokerages by requiring more disclosure on how they handle orders for large institutional investors.
