ChatterStock gathers tweets in real-time to provide a “perception” score for stocks in the S&P 500. In short, ChatterStock aggregates thousands of tweets from individuals and news agencies to measure the “buzz” for stocks in your portfolio.

Note: This app does not provide current or historcial stock values, but rather a score indicating the current perception of stocks within the S&P 500.

How does it work?

Your friends at AppScience, LLC have created a proprietary statistical model that analyzes “tweets” using Natural Language Processing (i.e. “Sentiment Analysis”) based on positive or negative language used in reference to the selected stocks. We then do some statistical kung-fu to ensure a valid comparison against other stocks (hi-ya!). The end result is a perception score ranging from 0 to 100, with 0 indicating the worst perception and 100 representing the best perception.
