Billionaire Mark Cuban cleared of insider-trading charges Mark Cuban, the billionaire owner of the NBA's Dallas Mavericks, won a lengthy fight with the Securities and Exchange Commission on Wednesday when a Texas jury cleared him of insider-trading charges. The SEC had accused Cuban of using non-public information about Mamma.com, a Canadian Internet company, to make trades that helped him avoid about $750,000 in losses. Cuban, 55, denied the charges during testimony at the federal courthouse in Dallas. A nine-member jury deliberated about four hours before clearing Cuban. The SEC had sued Cuban, seeking a fine equivalent to the losses Cuban avoided by selling shares of the search-engine company in 2004.

Cuban sold the shares a few hours later, before the company announced the stock offering to the public, triggering a sell-off that drove down the value of its shares. Cuban's lawyers argued that he was not prohibited from selling his shares. The flamboyant Cuban, who has been fined more than $1 million for criticizing NBA referees, accused the SEC of targeting him as a vendetta because of his political views and wealth.
