Johan Bollen, a professor of informatics at Indiana, co-authored a study that linked a computerized assessment of the ‘mood’ of millions of Twitter posts with stock marketperformance.

Mr Bollen’s analysis of Tweets was said to have an 87 per cent chance of successfully predicting stock prices within three or four days of online discussion of the company in question.

To reach his conclusion, Mr Bollen analyzed a total of 9.6 million tweets over nine months in 2008, using two mood-tracking tools.

One program assessed whether a tweet about a particular company was positive or negative, while the other tried to drill down further and categorize tweets through six modifiers: calm, alert, sure, vital, kind and happy.
