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.

Stocks continue to hold up like troopers even though bulls have lost some traction, perhaps due to a combination of the summer doldrums and overbought technical conditions that have them biding time until the next setup for a run at new highs. To be sure, bears are AWOL and missing their opportunity to create some fear and ignite a correction.

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.

Well, it’s official. The old adage about selling in May didn’t apply this year. Instead, larger-cap, higher-quality, and value-oriented stocks continued to lead the market higher. The S&P 500 gained +2.1% during the month and confirmed its tentative technical breakout from the prior Friday with steady progress last week. However, it was tepid at best during the holiday-shortened week, and a somewhat concerning ‘double-low’ confirmation -- i.e., on extremely low (and decreasing) volume and with a backdrop of persistently low volatility.

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.

Rather than a Great Rotation from bonds into equities, the rotation instead has been from growth into value. Among the ten U.S. business sectors, uber-defensive sector Utilities is still the clear leader year-to-date, up more than +10%, followed by Energy and Healthcare. Healthcare and Materials were the leaders last week. Consumer Services/Discretionary remains the clear laggard YTD. Moreover, rather than bond prices falling, the 10-year Treasury yield has fallen even further to 2.52%, further indicating a flight to safety.

The technical picture for stocks has shifted from bearish into neutral, and our fundamentals-based sector rankings appear to have moved from bullish to neutral, as well. Thus, caution remains the order of the day until either the bulls or bears can find a catalyst -- and enough recruits -- to move the ball in their direction.

Stock market bulls made a valiant effort to fight off another looming correction last week. The economy is showing strong signs of recovery, the Fed remains confident enough to continue its stimulus tapering, and attractive alternative investments to the U.S. stock market seem scarce. Yes, bulls are all dressed up for more fun times. However, the technical picture paints a different story, at least for the near term.

Overall, the economy appears to be on a steady path to recovery. As the Federal Reserve eventually allows interest rates to rise, we likely will see a rotation out of value and into growth as defensive debt-intensive companies struggle relative to companies that have lower debt burden and stronger prospective earnings growth.
