Socially generated financial data the next big thing?


A ton of articles/papers released recently on this topic:

Social media seems like the best way to gauge sentiment without actually asking the person. Bloomberg has already included Twitter feeds on their platform, Yahoo Finance has StockTwits feeds integrated on their stock pages. StockTwits hasn’t even released their API yet. With the rise of social media, will we see the rise of socially generated financial data?

All the above algorithms that trade Twitter sentiment are very short term. This could be due to the fleeting nature of Twitter posts, thus relevant financial tweets are dominated by those from short term traders with short term outlooks. Social media gauges short term sentiment, but its hard to tell whether it can gauge what I call longer term “behavioral biases” such as price momentum (“let’s jump on the bandwagon”) and post earnings announcement drift (people being slow to realize and price in the better prospects suggested by a positive earnings surprise).
