> I mean, simple Google produced result I shared Yes, and that was an interview between Barry Ritholtz and James O'Shaughnessy of O'Shaughnessy Asset Management, and not someone from Fidelity. Here's O'Shaughnessy again on that anecdote: > 1/That story was told to me by a former colleague which perhaps allowed me to lower my guard on it. When I went looking for it, I found nothing.

But if you're going to encourage people to do it perhaps use studies that actually exist.
