“To find out if the “market sentiment” expressed in Twitter is correlated with actual market behavior, we at BBVA have launched Stockbuzz (www.stockbuzz.es). This is a site where the user can view the sentiment that Twitter users feel on the Ibex 35 and the securities that make up the index, and compare it with their actual share price on the stock exchange. 

The website is user friendly, easily understandable and attractive. It shows graphs and data based on the information that is posted on Twitter, but also promotes interaction with this social network, as it contains a section where site visitors can leave their own messages on the analyzed stocks.”
