The market has modes and reverts behavior when it switches them. Thus happy bouncy becomes hammered stammered. The prediction models fall hook and sinker for that.

There is no model of the market that can remain stably accurate because the market will inevitably incorporate the insights of any model that is accurate until those insights are no longer accurate
