Human psychology plays a massive role in the world of investing.
“To suppose that the value of a common stock is determined purely by a corporation’s earnings, discounted by the relevant interest rates and adjusted for the marginal tax rate, is to forget that people have burned witches, gone to war on a whim, risen to the defense of Joseph Stalin and believed Orson Wells, when he told them over the radio that the Martians had landed.”
