Convicted Stock Manipulator; Vice Chairman of GAF Corporation
Vice Chairman, GAF Corporation
James Sherwin was the vice chairman of GAF Corporation who was convicted of manipulating GAF's stock price during a hostile takeover attempt of Union Carbide in the mid-1980s. Sherwin directed brokers to make artificial trades to inflate GAF's stock price, creating a false impression of market demand. The case required three trials (two ended in mistrials) before a jury convicted Sherwin in January 1990 of stock manipulation. He was sentenced to six months in prison. The case demonstrated how stock manipulation was used as a tool in the corporate takeover wars of the 1980s.
