Well, when people are getting hysterical, you can sense it just by market action. If you read the press, you can see when everybody's talking about whatever it is that's the best thing, something going to change everybody's life and how boy, it's a whole new era. You hear the same words every time, every time - they are the same. Investors and the press use the same expressions about how great things are now. For example, Amazon (AMZN) can never go down and will never go down and is going to go own the world someday.
