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.

Wall Street is on a nice little run at the moment, precisely the sort that is almost too seductive to avoid. So does that in fact make it the time to avoid it?

Maybe, maybe not. Yet bandwagons should be, at the very least, soundly considered prior to hopping aboard one.

The S&P 500 closed today at 1309, down well over 1%. The NASDAQ closed down nearly 2%.  In light of relative valuations and current global prospects for the past six months, the question begs an answer: Why?  Let’s begin with an overview of the results of the past week.

Here we are again wondering what the market wants.  Today, it clearly wasn’t Technology stocks, as various issues dragged both Apple (AAPL) and Google (GOOG) lower.

Last week the market (S&P 500) battled resistance at the 1100 mark as if it were in the yawning sand trap at #14 on Pebble Beach – and Tiger Woods can't help us out just now.

Since the unemployment release of 10.2% on November 6, virtually all economic releases have been modestly positive and the late reporting companies have had strong results (including revenues) and strong guidance.  So why has the market been going up and down on a daily basis over the past week?
