The Securities and Exchange Commission (SEC) later announces that they are investigating the trading of shares of 38 companies in the days just before 9/11. The San Francisco Chronicle reports that the New York Stock Exchange sees “unusually heavy trading in airline and related stocks several days before the attacks.” All 38 companies logically stand to be heavily affected by the attacks. They include parent companies of major airlines American, Continental, Delta, Northwest, Southwest, United, and US Airways as well as cruise lines Carnival and Royal Caribbean, aircraft maker Boeing and defense contractor Lockheed Martin. The SEC is also looking into suspicious short selling of numerous insurance company stocks, but, to date, no details of this investigation have been released.
