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.

Once again, stocks have shown some inkling of weakness. But every other time for almost three years running, the bears have failed to pile on and get a real correction in gear. Will this time be different?

Despite a highly eventful week in the news, not much has changed from a stock market perspective. No doubt, investors have grown immune to the daily reports of geopolitical turmoil, including Ukraine vs. Russia for control of the eastern regions, Japan’s dispute with China over territorial waters, Sunni vs. Shiite for control of Iraq, Christians being driven out by Islamists, and other religious conflicts in places like Nigeria and Central African Republic.

More unnerving conflicts around the globe have flared up, but as usual, U.S. equity investors have given it nary a yawn as they seem to have become pretty much numb to the steady stream of unwelcome news, particularly out of the Middle East. Now we enter the summer version of earnings season.

Stock investors entered the Fourth of July holiday on a high note, pushing the Dow Jones Industrials Index above 17,000 and the Wilshire 5000 Total Market Index above 21,000, and even pushing the S&P 500 to a smidge above the upper trend line of its long-standing bullish ascending channel that has been in place for nearly three years.

U.S. stocks just continue to cruise right along, although investors seem to be displaying a healthy level of caution, looking over their shoulders as they whistle past the graveyard and bet on ongoing improvement in corporate earnings and economic growth. Despite extremely overbought technical conditions and regional hot spots that may ultimately threaten global economic recovery, investors seem undeterred.

After its long-awaiting breakout of the 1900 level the other week, the S&P 500 gained another +1.3% last week alone, but this double-low progression as I call it -- i.e., on extremely low volume and with persistently low volatility -- is worrisome.

Stocks ended last week on a high note, closing a smidge above strong resistance at 1900 for the S&P 500, which set a new closing high for the large-cap index, albeit on low pre-holiday volume. With the Memorial Day holiday giving us a short week of trading, all eyes are on voting in Ukraine, where a decisive win for billionaire business tycoon Petro Poroshenko seems assured.

It was yet another week of hanging around the1100 mark with the S&P500. It's not that there weren't important developments during the week. The trade deficit narrowed much more than expected, and retail sales got a substantial boost in November. Retailers alone sold $314.1 billion of goods, 1.4% more than in October and 2.2% more than a year earlier.
