On the irrational response to irrational exuberance: "Only on Wall St do people get excited as the prices go higher and get disgusted as prices go lower. People assume that a low price means there's something gone wrong with the company and they shun it like the plague. But when prices go high, people think there's something going on and must own it. It's not greed that drives markets, it's envy. People buy stocks and get involved in these manias because they fear that their neighbour is getting rich and that they're missing out." - Adam Crowe
