I like the sound of this, taken from "Business Unusual" blog:
Twitter A Crystal Ball For Predicting Stock Market?
Hedge funds are volatile investments for the super rich to make (or lose) piles of money very, very quickly. It’s a cutthroat business. Because funds are only as good as their last reported performance, managers will do almost anything to get an edge and deliver the best returns to clients…so they’re not below using Twitter as a crystal ball.
Derwent Capital is Europe’s first “social media based hedge fund.” The fund managers use an algorithm to analyze thousands of random tweets on Twitter for words like happy, sad, angry, jerks, depressed, pissed-off, etc. to determine public sentiment or mood.
According to the brains behind the proprietary algorithm there is a surprising correlation between the mood of Twitter users today and the movement of the stock marketing in the next 2-3 days…turning Twitter into a crystal ball.
