Also in M is the ability to pay as, for instance, a spent-out bull can't make the market go higher and a well-heeled bear won't. This view of the world is, at least in my opinion, consistent with the empirical observations of anomalies such as the value, momentum, and mean-reversion factors especially when we acknowledge that these factors tend to exhibit cyclical behaviour.

Jesse January 15,1: These two theories are impossible to prove but they are what I personally believe about the markets in addition to my belief that they are not random, but rather appear random just like many other complex adaptive systems.
