We recently presented a look at some of the most notorious financial felons of contemporary times.

Since then, news has included the indictment of Mark Cuban for insider trading in a case that is somewhat reminiscent of Martha Stewart's case. According to the SEC, the billionaire entrepreneur asked his broker to sell all his shares of Mamma.com after the company's CEO confidentially told him of an impending stock offering that would dilute the value of all existing shares. By selling before the information became public, Cuban is said to have sidestepped losses of more than $750,000. Cuban insists, though, that no agreement existed to keep the information confidential.

And then there was the indictment in Texas of Vice President Dick Cheney, along with former U.S. Attorney General Alberto Gonzales and others. There seems to be a conflict of interest between the vice president's influence on the federal agency that oversees federal immigration detention centers and his substantial holdings in Vanguard Group, which invests in private prison companies. But does the lame-duck county district attorney, who was a no-show in court, have the authority to bring charges against federal officials with regard to federally run institutions?

This post is part of a feature in which we wonder whatever happened to some notorious financial felons. See all 17.

Ah, for the simple days of the 1980s. Way back then, the crimes of greedy traders were obvious and unambiguous, and the crooks had the decency to look the part. Few played the role of the greedy financier as well as Ivan Boesky, who went all the way from immigrant's son to millionaire investor to disgraced jailbird. I only wish our current financial crooks played their parts as well.

Ivan Frederick Boesky rose to fame and fortune taking huge positions in companies that were soon to be taken over. He was quite successful during the merger mania that drove the 1980s boom market, and by 1986 he was worth over $200 million, which was real money back before hedge funds took over the world. The only problem was that he was trading on inside information, which while enormously profitable has the distinct disadvantage of being completely illegal.

Boesky was not subtle in his approach, often buying tens of thousands of shares in a company at a premium just days before the company announced a takeover. The share price would jump and Boesky would quickly cash out. The typically somnambulant SEC eventually took notice, and Boesky was caught red-handed in 1986 and charged with stock manipulation and insider trading. He paid a fine of $100 million and spent nearly two years in the (minimum security) slammer. He also sang like a bird to the SEC, providing enough information about crooked dealings on Wall Street to almost single-handedly bring the 1980s boom to an end.
