To put it in simple words, when the emotions on twitter
fly high, that is when people express a lot of hope,
fear, and worry, the Dow goes down the next day.
When people have less hope, fear, and worry, the
Dow goes up. It therefore seems that just checking on
twitter for emotional outbursts of any kind gives a
predictor of how the stock market will be doing the
next day.
