Investors find themselves paralyzed by uncertainty given mixed messages from prominent market experts and talking heads, some professing the sorry and deteriorating state of the global economy, and others cheerleading the continued improvement in the fundamentals, particularly here in the U.S. Indeed, the nearly identical chart of the S&P 500 in 2015 compared to 2011 gave hope to a similarly solid start to 2016 as we saw in 2012, but instead we have seen the worst start to a New Year in history.

Even with many of the global issues pushed off the front page, eager bulls found yet another reason to keep the troops in the barracks. The only newsworthy items are related to corporate earnings reports, which have been mixed at best, interspersed with the occasional spectacular report -- primarily from mega-caps like Google (GOOGL), Facebook (FB), or Amazon (AMZN). Some of the bulls have taken their chips off the table until after Labor Day, while others have merely scaled back to scalping some trades. Either way, stocks appear destined to thrash about for the rest of the summer.

Early last week, stocks broke out, with the S&P 500 setting a new high with blue skies overhead. But then the market basically flat-lined for the rest of the week as bulls just couldn’t gather the fuel and conviction to take prices higher. In fact, the technical picture now has turned a bit defensive, at least for the short term, thus joining what has been a neutral-to-defensive tilt to our fundamentals-based Outlook rankings.

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.

Despite low trading volume, a strong dollar, mixed economic and earnings reports, paralyzing weather conditions throughout much of the U.S., and ominous global news events, stocks continue to march ever higher. The world remains on edge about potential Black Swan events from the likes of Russia, Greece, or ISIS (or lone wolf extremists). Moreover, the economic recovery of the U.S. may be feeling the pull of the proverbial ball-and-chain from the rest of the world’s economies. Nevertheless, awash in investable cash, global investors see few choices better than U.S. equities.

Investors in U.S. equities seem to have embraced a new market paradigm in which upside spikes come more swiftly than the downside selloffs. Remember when it used to be the other way around? When fear was stronger than greed? The market is consolidating its gains off the early-October V-bottom reversal, and no one seems to be in any hurry to unload shares this time around, with the holidays rapidly approaching and all.

The market continued its slow but persistent trek upward, inching along as it did during the holiday-shortened past week. In fact, the S&P 500 set an 18-month high today at 1187.73 and closed very near the high.
