I gave you the answer to your question which involved the first 45 minutes.
The market continued its downturn because of the subconscious realization that Henry Waxman and the rest of the morons in congress have no idea what they did.
The market started back up when Bush spoke and gave a glimmer of understanding. They will go back down when people realize that although he talks the talk, it is from a script, written to justify his moronic decisions during the last 8 years.
