The Wall Street Journal reports, "Money managers SAC Capital Advisors, Janus Capital Group Inc. and Wellington Management Co. have received inquiries in the ongoing insider-trading investigation on Wall Street." Yesterday, the FBI raided three hedge funds—two of which are run by former SAC managers—as part of the government's insider trading crackdown. A securities law professor at Columbia told Bloomberg News, "[The feds] appear to have an interest in some of the traders who used to work at SAC Capital. Those traders that the government seems to be pursuing have to make a quick decision about whether they’re going to cooperate or whether they’re going to fight. They will get greater leniency if they give the government bigger fish."
