"After taking risk into account, do more managers than you'd see by chance outperform with persistence? Virtually every economist who studied this question answers with a resounding 'no'. Mike Jensen in the sixties and Mark Carhart in the nineties both conducted exhaustive studies of professional investors. They each conclude that in general a manager's fee, and not skill, plays the biggest role in performance."
- Eugene Fama, Jr.
