I would not put it past market to fall tomorrow, but most likely, as after the TARP bill in oct 2008, we get a 2 day 19% rally. There were 5 rallies between the middle of sept and end of oct 2008 that were 12%, 24%, 19%, 14%, and finally 21% on the day the money was given out to the banks.
So a 2 to 5 day rally would be a great short op.
