I have a name for people who went to the extreme efficient market theory-which is "bonkers". It was an intellectually consistent theory that enabled them to do pretty mathematics. So I understand its seductiveness to people with large mathematical gifts. It just had a difficulty in that the fundamental assumption did not tie properly to reality.
Charlie MungerI think there's an awful lot of twaddle and bullshit on EVA. The whole game is to turn retained earnings into more earnings. EVA has ideas about cost of capital that make no sense. Of course, if a company generates high returns on capital and can maintain this over time, it will do well. But the mental system as a whole does not work.

Charlie MungerI mean people are really crazy about minor decrements down. And then, if you act on them, then you get into reciprocation tendency, because you don't just reciprocate affection, you reciprocate animosity, and the whole thing can escalate. And so huge insanities can come from just subconsciously over-weighing the importance of what you're losing or almost getting and not getting.
