Can Twitter Predict the Volume and Price of a Specific Stock?

In a world where everyone’s opinion is publicly recorded, it should be theoretically possible to determine the most popular concept of the moment — be it a movie, a song, a feeling or even a stock.  Certainly, we don’t have enough information at this point to record everyone’s fleeting thoughts, but Twitter is something that makes a good temporary approximation.  And that’s what led University of California, Riverside professor Vagelis Hristidis to investigate whether Twitter sentiment could help predict the stock market.
