STANLEY DRUCKENMILLER: “I JUST DON’T CARE WHAT I PAID FOR A STOCK. IT’S ABSOLUTELY IRRELEVANT.” “If the reason I bought a stock is no longer the case, I don’t care if I bought it at 60 and it’s 50. I have no emotion whatsoever.” “There’s resistance at certain prices because a bunch of people bought at 60, it went down, and they’ve been waiting 3 or 4 years for it to get back. Meanwhile they could’ve been in something else going up the whole time.” His friends and fellow investors say he’s “entirely unemotional.” His response: “Yes. I’m told that’s true.” Is that the key to his success? “I think it’s a big part of it. Being open-minded and having humility. The only reason you can change your mind is if you’re not arrogant about a position.”
