FYI: In my early years on Morningstar's mutual fund analyst team, I absolutely loved the idea of Davis Funds' "Mistake Wall."
"We're in a profession that's very different from football," says fund manager Chris Davis in a video about the wall. "We should be getting better with age. We have the opportunity to gain experience, and from experience comes judgment, and from judgment comes investment wisdom. So we try to learn from the mistakes."
