this to shake out and we have seen significant movement in this final hour of trading and where we end up i think will tell us something. you just said something i think we need to unpack. you talk aboutal algorithms an programs. the last time we saw a thousand on the dow. it had to do with a flash crash. there is a difference between the way stocks were traded today and when we got into the business. it was hard to have big crashes because you have a floor full of people would were buying and selling and understand what is going on n. this day and age, we have no idea what kind of sentiment is behind a 8,000 did, 1200, 1400 drop. and you could have a a little increment of sentiment change that then feeds upon itself for an hour or two hours, three hours and then things correct themselves if you don t have a fundamental problem.
