The Wall Street Journal reports this morning the SEC (Securities and Exchange Commission) has filed Insider Trading charges against Mark Cuban. The charges reportedly stem from unloading shares of Mamma.com (after learning of a private offering funding).

The SEC believes that Cuban allegedly sold his 6% ownership just before a public announcement which saw shares of Mamma.com drop 10%. The sale of shares saved Cuban around $750k.
