Ethanol stocks options heat up ahead of Bush speech

CHICAGO (Reuters) - Many investors flocked to bullish options in producers of ethanol on Friday ahead of U.S. President George W. Bush's State of the Union annual address, which is expected to call for expanded use of the clean fuel.

Bush's annual speech to Congress on Tuesday could call for up to 60 billion gallons of ethanol -- produced mostly from corn in the United States -- and biodiesel annually by 2030, according to a source briefed by the White House.
