Dallas Mavericks owner Cuban charged with insider trading

Entrepreneur Mark Cuban, owner of the National Basketball Association’s Dallas Mavericks, was charged Monday by the Securities and Exchange Commission with insider trading.

According to the SEC, Cuban sold 600,000 shares of Internet search company Mamma.com in June 2004 using non-public information. Cuban is accused of calling his broker and instructing him to sell all of his stock from the Mamma.com after receiving confidential information from the company.

The SEC said Cuban knew the stock price was about to fall.
