Which get's into the short vs long term problem. In the short term strategy X works, in the long term it failed. How much of that success is random chance and how much is the value of the underlying data? And how do you avoid losing all benefit when the strategy eventually fails?

The reality is this kind of short term incite based investing does not really scale. Over time the money you spend on paying people to do this is less than your risk adjusted long term benefit.
