The Wall of Worry just keeps adding more bricks. Although there has been much talk about the impact of low oil prices on the U.S. high yield debt market and by extension the U.S. banks that did the lending, the bigger worry now is the stability of the European banking system. It is like 2011 all over again. Also, there continue to be signs of an insidious corporate “earnings recession.” Such headlines add to the steady stream of “worry bricks” that have so confounded disciplined fundamental investors for at least the past seven months or so.

Headlines continue to dominate the trading landscape, perpetuating a news-driven trader’s market rather than allowing a healthier valuation-driven investor’s market to return to favor.

The S&P 500 large caps closed 2015 essentially flat on a total return basis, while the NASDAQ 100 showed a little better performance at +8.3% and the Russell 2000 small caps fell -5.9%. Overall, stocks disappointed even in the face of modest expectations, especially the small caps as market leadership was mostly limited to a handful of large and mega-cap darlings.

But this year’s market has been news-driven and quite difficult for traders to read. Even our fundamentals-based and quality-oriented quant models have struggled to perform.

The Fed’s decision to not raise the fed funds rate at this time was ultimately taken by the market as a no-confidence vote on our economic health, which just added to the fear and uncertainty that was already present. Rather than cheering the decision, market participants took the initial euphoric rally as a selling opportunity, and the proverbial wall of worry grew a bit higher.
