This is due today at 9:45. I believe Bloomberg.com pointed out a while ago that you can pay to subscribe to this and know what it is going to be before it is announced. So any plunge on it being "worse than expected" may just be easy money for those accounts. There are other surveys such as from IBD that seem to be correlated as well. In their Feature Story on 9/11, they say: "IBD/TIPP's National Outlook Index, based on polling from Sept. 2-8, fell 2.7 points to 49.5. That's the lowest since the poll was launched 32 months ago with President Bush's inauguration." Even considering this, would you still always be flat prior to this report, as with other economic reports?
