VIDEO: Using Tweets to Predict Changes in Stock Price

Here's a really interesting ECE capstone design project. Shihao, Tingkai, Fanzeng, Yuhan and Professor Zhu have developed a system to predict short-term changes in stock prices using recent data gathered from twitter. They're achieving predictive accuracy close to the state of the art. Imagine what you could do as a day trader if you could make better-than-baseline predictions of stock prices.
