Lately futures have not been as accurate at forecasting the open. I have noticed on dow futures today and yesterday they are ofter very high pre market like they are being bought by some goverment agency. But it isn't working very well because they spend the rest of the day trending downward. Just look at todays chart of YM. At 2:44 ET in the morning we had a high of 9246. Maybe this is just trend buying I don't know. But what on earth justifies that much above the previous close? Especially after yesterday's 400 point selloff at the end of the day? What do you think?
