Think back to last Friday morning in the pre-market hours. Futures limit down. CNBC announcing circuit breaker levels. If you knew in advance that Friday and Monday would be down days, with vicious selling near the close, would anyone believe that the Dow and S&P cash markets would still be holding above their Oct. 10 lows? Maybe that will change tomorrow. Or maybe the "selloff before Fed announcement day"/"buy on Fed day" (regardless of what the Fed says or does) will hold again. But I'm still surprised it hasn't been worse.
