Cuban’s Long-time Stockbroker Takes the Witness Stand

Mark Cuban’s long-time stockbroker told a federal court jury Tuesday that corporate compliance officials at UBS Financial Services raised no red flags or concerns about the legality of Cuban’s sale of Mamma.com stock in 2004.

But lawyers for the U.S. Securities and Exchange Commission, in a series of heated exchanges with the Dallas-based investment broker, attempted to undermine the witness’ credibility by showing his financial dependency on Cuban.
