Yesterday's selling should mark the low. A confluence of negative factors (terror warnings, pre-holiday sales, and bad accounting news) combined to push the markets lower. The put/call ratio was over 1 at the end of the day, showing excessive pessimism. The Dow didn't break last week's lows and the breakdown in the S&P was not convincing.
Today: The market is poised to rally. The initial jobless claim number may get the credit, but investors are likely to focus on any good news or even the absence of bad news. Expect a rally to one of the many resistance levels.
Support: Dow 8,926, S&P 945, Nasdaq 1,356
Resistance: Dow 9,400, S&P 1,005, Nasdaq 1,485
