“But most investors do capitulate eventually. They simply run out of the resolve needed to hold out. Once the asset has doubled or tripled in price on the way up — or halved on the way down — many people feel so stupid and wrong, and are so envious of those who’ve profited from the fad or side-stepped the decline, that they lose the will to resist further. My favorite quote on this subject is from Charles Kindleberger: “There is nothing as disturbing to one’s well-being and judgment as to see a friend get rich” (Manias, Panics, and Crashes: A History of Financial Crises, 1989). Market participants are pained by the money that others have made and they’ve missed out on, and they’re afraid the trend (and the pain) will continue further. They conclude that joining the herd will stop the pain, so they surrender. Eventually they buy the asset well into its rise or sell after it has fallen a great deal. In other words, after failing to do the right thing in stage one, they compound the error by taking that action in stage three, when it has become the wrong thing to do. That’s capitulation. It’s a highly destructive aspect of investor behavior during cycles, and a great example of psychology-induced error at its worst.”
