Stocks reversed their recent downward trend Tuesday immediately following early reports, and a later confirmation from U.S. Central Command, that two men killed in a six-hour shootout in the northern Iraq city of Mosul are the sons of former dictator Saddam Hussein. Odai and Qusai were ranked Nos. 2 and 3 on the U.S. most-wanted list in Iraq.

"The market is celebrating a bit," Arthur Hogan, chief market analyst at Jefferies & Co., told The Associated Press. "One of the major pieces of background noise [in the market] was the disappointment that we don't have clear evidence of weapons of mass destruction [by Iraq] or clear evidence that we have Saddam Hussein or any of his direct relatives."
