This is nonsense - I know people in quant funds who have tried to do things like this. All the boring stuff that Google doesn't care about, like SEC filings and Quarterly Reports, matter <i>far</i> more than aggregate attention. I'm sorry but if you're making decisions for a multi-million dollar fund, and you tell investors that your investments are based on the twitterings of the unwashed masses, you'll be sent home before you've had your lunch.<p>Even if there is value in their data (and I do imagine enough PhD's could find some reasonable strategies) - there would be such a public outcry that it wouldn't be worth it from a PR perspective.
