No Place to Hide

Perspectives

The last quarter of 2018 marked the dramatic end of the longest bull market in financial history, nine-and-a-half-years (115 months) of generally rising U.S. stock indices. December was the worst performing month since the Great Depression and the year was the worst since 2008. The quarter was notable for almost unprecedented market swings and volatility. By year end, major U.S. equity indices were close to bear market territory, in marked contrast to where they were on September 20th, with a nearly 10% gain for the year. However, from a longer-term perspective, returns over a two and five-year period remain very positive.

Normally, at least one major category of global investments is positive for the year. But the year 2018 was notable as no place to hide. Stock markets around the world were twice as bad or more than the U.S. During the year oil and copper swung from gains to losses while bond indices were negative or neutral. Cocoa was one of a very few assets that beat cash for the year.

The fall in security prices is, in hindsight, not that surprising. We noted in our 3rd quarter commentary that a feeling of investor complacency had settled in with expectations of a norm of steady gains and minor interruptions. American equity investors had become presumptive of a goldilocks era of quantitative easing and good government and corporate financial management, particularly when compared with other parts of the global economy. But the list of potential economic and financial disruptive factors continued to pile up during the year and into the 4th quarter. How long could the market ignore a no longer accommodative Fed, threats of government shutdowns, inflation fears, domestic and global political dysfunction, and tepid and negative international economic and financial data?

In the final moments of the 4th quarter, a point of major investor sentiment disequilibrium occurred and the market responded with a roar. Market volatility experienced in the last week of 2018 has been described as something no one has ever seen before. A 700-point decline in the Dow followed by a 1000-point rise the following day followed by a 600-point decline during the day only to end up 200 points above the prior close at the end of the day. The result was a dizzying investment moment. How to understand such persistent dramatic volatility? Is cash ultimately the only safe asset? Academic theories of market equilibrium and expected value seem far removed from financial reality.

The fact that eighty-five percent of all trading is said to be on automatic pilot is a convenient rationale for explaining waves of up and down stock prices over short time periods. Rule-based, model, and passive strategies can result in trade herding over short periods. But persistent volatility during each of the three days, including changes in direction and of the magnitude observed, is not very consistent with other examples of bursts of computer-driven volatility which tended to be very short-lived.
