“I’ve probably had a hundred ideas of things that should be shorted, and I would say that almost every one of them have turned out to be correct. And I’ll bet if I’d tried to do it and make money out of it, I probably would have lost money, I would have had no fun, and the opportunity cost, as Charlie said, would have been enormous. Because if somebody’s running something that’s semi-fraudulent, they’re probably pretty good at it and they’re working full time at it and they’ve succeeded for a while and they may keep succeeding. And if they succeed and you go in at X and it goes to 5X, you know, all you’re hoping after a while it that it goes back to X again or something of the sort. It’s a very tough psychological game to play. Few people may be well-suited for it. I would never put any money with a short fund, but not because I would think it would be ethically wrong. I just think they’re unlikely to make money.” –Warren Buffett.
