Quote from tivthetrader:
I think there is a large short, or short fund in trouble and being liquidated. Just from the trading action the last couple of days, you would see a couple of downticks on the es and then they would come in above the ask with a bid. Nobody would voluntarily trade like that, but a risk manager liquidating a position would. Also, I have total respect for the bull run and all that, but as a manager who was long during this big run, why woud i buy at the close into a 3 day weekend with all the stuff going on in the mideast and all the other stuff. Again, I think it was a short squeeze or liquidation.
