The 9 Most Notorious Insider Trading Cases of 2011
Donald Johnson, the former managing director of the market intelligence desk at Nasdaq, was sentenced to nearly 3 years in prison in August for insider trading. He pleaded guilty earlier this year to using the advanced information he got in his role at Nasdaq to make illegal trades. Regulators said his scheme earned $755,000 in illegal profits over a three-year period. "This case is the insider trading version of the fox guarding the henhouse," said Robert Khuzami, the SEC's director of enforcement.
