Last week, the major indexes fell back below round-number thresholds that had taken a lot of effort to eclipse. There has been an ongoing ebb-and-flow of capital between risk-on and risk-off, including high sector correlations, which is far from ideal. But at the end of it all, the S&P 500 found itself right back on top of long-standing support and poised for a bounce, and Monday’s action proved yet again that bulls are determined to defend their long-standing uptrend line.

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.

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.

Bulls continue to climb their wall of worry, as uncertainty from the latest “bricks in the wall” created by Russia in Crimea, slowing growth in China, and Fed tapering fades into the mosaic.

The U.S. stock market has been reluctant to provide eager bulls with a tasty entry point ahead of the much anticipated year-end rally. Although the major indexes have seen fit to consolidate a bit and work off some of their overbought conditions, bulls have hoped for a something more substantial. But very few holders are selling these days.
