Remember "irrational exuberance?" Well the bulls are running rampant dumping shitloads of cash into funds. Funds bulging with cash from folks who are far too eager to plunge into this very old bull market. All of a sudden some respected sources are seeing a monster sell off, like now. This market at 11,000 is up from 5,000 plus just six months ago. One of the oldest indicators in the biz is the number of bullish or bearish ads in Barrons. When they're predominently bullish it's over and that's where it is right now.
