I'm honestly surprised that these companies haven't started extracting business intelligence information from their data flows and using it to make investment decisions in public companies. Surely there's a correlation between how often people search for "JC Penny" and JC Penny's earnings. And these companies have far more data than that, alongside a giant pile of money that they can use to fund an investment arm.
