Deja BTFD

Since mid-July, the S&P 500 is practically unchanged having ebbed and flowed on lower and lower volumes. But one thing that is very clear in the last few weeks, investors seem to have been conditioned to sell early and BTFD late... The question we have is (given the S&P is approaching its worst week of the year), when everyone 'knows' this is the strategy, when does it become self-defeating?

S&P 500 futures from 8amET to 1400ET in the last few weeks...

of course - at some point that 'buy' won't work...
