Ever since I started following stocks again, I have been preoccupied with developing a "game plan" to help prevent me from making emotional investment decisions.  Plans can be improved.  What I have come up with so far is a stress avoidance model to study how different character types might perform in relation to the market.  Since quite a number of investors are actually algorithms - and many trades are algorithmically triggered - the concept of stress needs to be more liberally interpreted.  What "stress avoidance" means to a ...
