Tech billionaire, anger-driven blogger , and owner of the Dallas Mavericks Mark Cuban has just been charged with insider trading by the SEC. The (civil, not criminal) charges center on an incident in 2004 in which Cuban allegedly got early insider information about a company he had an ownership stake in, and used that info to avoid a loss of $750,000. We have no idea whether the charges are true, but if they are, it's a foolish business move by a guy who's already been fined more than twice that much by the NBA just for running his mouth. Though it is possible to formulate a wild conspiracy theory about this! Mark Cuban would be just another rich guy except for his penchant for saying whatever pops into his head. He constantly criticizes the NBA, which is a no-no by owners. The flipside is he gets great PR. Although half of it is bad! Oh well. He also has a blog that is sometimes hilarious and not well thought out a bit. At the moment, Cuban wants to buy the Chicago Cubs from Tribune Co., which needs to sell the storied baseball franchise to raise cash, which it will burn in a vain attempt to save its newspapers. The idea of Cuban—a maverick —owning the Cubs absolutely kills traditionalists , who think he would totally ruin all the great Chicago traditions, such as having ivy on the outfield walls and losing constantly. So is it possible that there was some shady conspiracy that caused this allegation from 2004 to surface just in time to (likely) torpedo any chance Cuban has of buying the Cubs? You would have to be a crazy conspiracy freak to believe this, for which there is no evidence whatsoever, so please don't sue us.
