The use of social networks like Twitter and Facebook has grown exponentially over the last few years. Twitter, which was founded in 2006, had an estimated 200 million users on January 1 2011 with more than 95 million tweets sent per day. With this rapid growth and significant adoption, Twitter has become an important tool for businesses and individuals to communicate and share information. In addition, Twitter has rapidly grown as a medium to share ideas and thoughts on investing decisions. This research builds on prior published research and attempts to determine whether there is correlation between twitter and the stock market by studying sentiment, message volume, price movement and stock volume as well as the affect that a twitter user’s reputation may have on sentiment and the stock market.
