Allen Poteshman, a professor of finance at the University of Illinois, publishes a paper demonstrating that the insider trading in options on United and American airline stocks indicates someone profited from foreknowledge of 9/11. Poteshman concludes, “There is evidence of unusual option market activity in the days leading up to September 11.”
