Can Twitter Inform Stock Trades?

A hedge fund called Derwent Capital Markets says it will launch a new fund in February that will trade based in part on analysis of Twitter sentiment.

Researchers said they found that a change in emotions as expressed on Twitter would be followed by a move in the index between two and six days later, and that this method had greater than 87-percent accuracy.
