Multiple studies of profit/loss on Cramer’s picks have shown that on average he doesn’t beat the market.
However, I acknowledge those “studies” were done by financial news outlets (Barron’s…etc) who compete with Cramer in giving advice to investors, and invariably they give advice in a much different style than Cramer…so disdain him..which could obviously bias their “objective” evaluations of him.
I don’t have any reference to these studies, just remember reading articles about it in one of the five papers I get each day.
