The knowledge I have of the Stock Market can be fit into a thimble. However, I spent a couple of decades developing closed-loop PID motor control systems. Hence my observation regarding the similarities between the Stock Market and an under-damped closed loop control system. ;-) But it was simply an observation, nothing more. But it does seem that the entire concept of "Puts" and "Calls"(?) or whatever the terms are, is exactly based on exploiting the prediction of the periodicity of certain stocks and commodities.
And there are no more sure-fire examples of "follow the leader" than Stock Market Analysts. Considering the that that the ENTIRE reason stocks go up and down is because certain "experts" THINK it should go up or down at any given moment. Nothing more, nothing less.
And the model of stock prediction is somewhat like weather prediction. Where I live, it was predicted that we were going to have Snowmageddon this past weekend, starting on Saturday morning. So pretty much everyone rushed to the grocery store and bought out every single loaf of bread, dozens of eggs, and gallons of milk, to the point that they were COMPLETELY sold-out by Friday evening, like these supplies were going to be unavailable for another month or something. Guess what? We got rain instead of snow (for the most part); but there was DEFINITELY a "run on the stock market" (grocery stores), that was NOTHING more than the product of an INCORRECT PREDICTION.
IMHO, the Stock Market all-too-often behaves like the panicky shoppers, where the predictions quickly become self-fulfilling-prophecies "just because".
