Okay, here's my short term prediction based on what we know now, subject to change at any time.  

The market will briefly stabilize over the next few days as prices of individual company stocks adjust.  Up to now, stocks have been sold willy nilly, and there will be bargain hunting among the rubble.   Then after a few days of that, the market will slowly grind downward as buyers slowly realize the extent of the damage to the economy by people staying home and hunkering down.

This is the creative destruction of capitalism, where the weak are eliminated and the strong survive and prosper.
