Billionaire Dallas Mavericks pro basketball team owner Mark Cuban has been charged with insider trading according to information filed by the SEC. Cuban was charged with insider trading in shares of Mamma.com an internet search company in June 2004.

If anyone is a maverick, it's Mark Cuban. Not only is he the owner of the NBA franchise the Dallas Mavericks, he's a billionaire and Chairman of HDNet, an HDTV cable network. He's also poked his nose into things some think he should stay out of, such as commenting on politics and tech --- and blogging as well, on a blog with Maverick in its name. On Monday, he was charged with insider trading in the shares of Mamma.com by the Securities and Exchange Commission (SEC).
