No High-Frequency Crackdown in SEC Blueprint for Control

Mary Jo White’s blueprint for imposing tighter controls on high-frequency traders and some of the murky venues they inhabit stops short of a crackdown.

The U.S. Securities & Exchange Commission’s plan, unveiled by White in a speech this week, advanced some new ideas while borrowing heavily from existing proposals and measures that already have support on Wall Street. While stock exchanges, rapid-fire traders and private trading venues known as dark pools all would come under new scrutiny, White didn’t embrace the kind of tighter restraints that have been enacted in countries such as Australia and Canada.
