I guess such traders make higher profits in normal days, but are also more likely to fatally miscalculate when stocks fall. Testosterone correlates with taking risks, and risks are, naturally, risky.
Or, even more likely, traders who have good day and have perspectives for a success at work, develop high testosterone as result. Good mood raises testosterone.
It is this nasty question which kills 3/4 of evolutionary biology and evolutionary psychology. If research shows that some individuals enjoy more success than others (from
high-testosterone traders to long-tailed peacocks), why worse ones weren’t eliminated by evolution long ago?
