"This despite overwhelming evidence that even professional investors are no more likely to beat the market than monkeys throwing darts at securities listings. Money managers, at least, are paid to make investment bets. But why do amateurs believe they can outperform the professionals?" To answer this rhetorical question with a rhetorical answer, because amateur investors consider themselves to be smarter than monkeys throwing darts at securities listings. And as an amateur, I have been better than a monkey (or an index fund). But truth be told, if I had been pro, I would've held onto to everything I bought instead of ever selling it for princely profits.
