The market knows nothing about my feelings. That is one of the first things you have to learn about a stock. You buy 100 shares of General Motors (GM). Now all of a sudden you have this feeling about GM. It goes down, you may be mad at it. You may say, “Well, if it just goes up for what I paid for it, my life will be wonderful again.” Or if it goes up, you may say how smart you were and how you and GM have this love affair. You have got all these feelings. The stock doesn’t know you own it.

The stock just sits there; it doesn’t care what you paid or the fact that you own it. Any feeling I have about the market is not reciprocated. I mean it is the ultimate cold shoulder we are talking about here.
