Strange that I am updating this post for a third time and nothing really has changed, but the fact that nothing has changed is incredibly interesting to me. Since it is an update, I will not duplicate the explanation, so please read the last version Opinions Not Backed by Money Are Not That Believable--Updated and with R. The basic conclusion is that we are in a bull market and AAII surveys are bullish, but nobody is willing to bet money on a good stock market.
