Shorting here would be too dangerous. It pays to stay in cash. If you have been a holder of long position, hold on your shares for a little while. Market will have a 300+ point bounce shortly. Good stocks will rebound very quickly along with the market.
My own speculation is that we will open low tomorrow to flush out last sellers and dow will probably hit 10,000 (which is a pivotal point). After that, market will rise sharply to kill put options.
