Abstract

This experiment analyzes “tweets” gathered from Twitter and determines whether the positive or negative emotions conveyed in the contents of a massive collection of these tweets correlate with the percentage change in indexes of Standard & Poor's 500, the Dow Jones Industrial Average, and the NASDAQ stock markets. This experiment uses an algorithm that parses a random sample of live tweets and calculates their sentiment value, which is an indicator of whether a tweet is either negative or positive in its emotional content. The daily ­average sentiment value is then compared to the percent change in the stock exchanges.
