I 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 think it is undeniably true that the human brain must work in models. The trick is to have your brain work better than the other person's brain because it understands the most fundamental models- ones that will do most work per unit.
