Indeed trading seems to lag behind positive or negative Tweeting! Or, if you’re using the fancy stuff, tweets analysed in terms of the Google Profile of Mood States (Calm, Alert, Sure, Vital, Kind and Happy). And no, I’m not making this stuff up. And yes, you’re right, there’s money to be made here!
