As a rule, when the Fear Index goes up, the stock market goes down, and when the Fear Index goes down, the stock market's headed up. Here, I've used some basic math to directly compare the momentum of the NYSE Composite to the momentum of the VIX Fear Index. The idea is that extremes in fear--or euphoria--rarely last, and when these extremes fade, the pendulum of the stock market starts to swing the other way.
Often times, sentiment extremes tend to pulse before evaporating. In this chart, notice the second pulse of extreme bullish sentiment, identified by the red circle, and the market's peak last month.
Notice, too, the second pulse of extreme bearish sentiment, identified by the green
circle...right where we are now.
