Volatility reigned in January on elevated volume as stock investors shifted their focus from global events to U.S. earnings reports, which have ranged from amazing (e.g., Apple) to crushing (e.g., Microsoft). Although the earnings reports have brought plenty of surprises, the volatility is no surprise, as I and many other market commentators predicted for the New Year.

Now that’s what I’m talking about. I have been discussing the overbought technical conditions of the S&P 500 for some time and the need for a pullback to test bullish support levels. And as many commentators have suggested, the more time between pullbacks, the more severe is the action when it finally arrives. Bears had become very hungry after a prolonged hibernation. This week offered up a nasty pullback.
