The bottom line, the short-term trend is down. I hold both long (trapped) and short overnight.

Judging by how market closes, I guess we might see some weakness tomorrow morning at least. Statistics, however, favors a little little bit on the bull side as SPY has been down 5 days in a row, buy at today’s close, sell at tomorrow close, you’ll have 67% chances since year 2003. It’s not much edge especially if you have noticed that the drawdown is much bigger than the best gains.

If you consider SPX down 4 consecutive days then rebound 1 day like what happened today, buy at close then sell at close tomorrow, you’ll have only 43% chances since year 2003. So again, not much bull edges here.
