Basically, to take it out of the weeds (which this forum is not really prepared for) and reduce it down into a nutshell, it helps explain why the average investor has trouble nailing down consistently good investment strategies. This first link makes it all a bit more digestible to the average reader; the second is a good introduction, doing a sufficient job of laying out the main points to understand (esp. the first two pages).
This is my final comment on the topic, since such highfalutin' mathematical and statistical speculating isn't really necessary to the way I trade, invest, or view my relationship with the securities markets, though it may indeed be Disneyland for statisticians.
