Researchers have discovered that tweets can predict the outcome of the stock market, with an accuracy of around 90%.
Johan Bollen, associate professor of informatics at America’s Indiana University discovered the correlation between the Dow Jones Index and the collective mood of the public, via Twitter, 6 days ahead of schedule.
The study analysed more than 9.8 million tweets, from over 2.7 million users, between February and December of 2008.
