The Same Old Bear: A Study of Bear Markets and Stock Returns Since 1926

“THE ERROR OF OPTIMISM DIES IN THE CRISIS, BUT IN DYING IT GIVES BIRTH TO AN
ERROR OF PESSIMISM. THIS NEW ERROR IS BORN, NOT AN INFANT, BUT A GIANT.”
ARTHUR CECIL PIGOU

In the field of behavioral finance, there is a phenomenon called “barn door closing”. It describes the tendency of market participants to do today what would have worked yesterday—or last month, or last year. The best currentexample is the massive flight to perceived “low-risk” or “riskless” assets (bonds and treasuries), which fared very well during the market slide of October 2007 through March 2009, but which now have bloated prices and rather dim prospects.  Yields onT-Bills are essentially zero and the 10-year note yields 3.7 percent—both far below long term averages.


Lately, a very common request is an investment vehicle that is hypersensitive to (and avoidant of) downsiderisk, even at the expense of a considerable upside opportunity. Undoubtedly, this desire was precipitated by a decade during which investors were stung—not once, but twice—by severe bear markets. The only other decade that stocks suffered such declines (losses exceeding 40 percent) was the 1930s. Pessimism has clearly been born a giant in the aftermath of the credit crisis. Even now, with a market 63 percent above its March lows, fund flows in 2009 indicate that the investing public is still terrified of stocks and enamored with “low-risk” assets like bonds and treasuries. Year-to-date, U.S. equity funds have seen outflows of $22.8 billion dollars,while $330 billion has poured into U.S. Bond Funds, a trend which has only become more pronounced towards the end of the year.1 In the ever-shifting risk tolerance of the investing public, it is clear that right now investors would rather sleep well than eat well. This surge into fixed income comes at the end of a 25 year period where bonds have beaten stocks in the trailing one-, two-, five-, ten-, 15-, 20-, and 25-year periods.2 Even a cursory glance at history would inform these investors that the worst time to invest in an asset class is when it has had such a long run of strong relative returns. It is very likely that bond investors are positioned at the wrong end of a powerful mean reverting cycle. At current prices bonds and treasuries seem to us more likely to offer “return-free risk” rather than downside portfolio protection.

Of course, the best investment policy is one that looks forward not backwards, but this does not stop investors from systematically making market-timing errors. In a famous study conducted by Dalbar, in the 20- year period of fund flows analyzed, market timing stock fund investors lost an average of 3.29 percent per year while the average investor gained just 3.51 percent. Compared to a market that compounded at 12.98 percent in the same period, these investors were extremely unsuccessful.

Our opinion of stocks versus bonds has been very clear cut all year— in earlier commentaries beginning in January 2009,* we have outlined why 2009 was a once-in-a-generation opportunity to buy stocks and why investors making large allocation shifts away from equities and towards bonds are likely making a very costly mistake.


We are fortunate to have access to additional market data that helps put the recent stock market into historical perspective. The purpose of this study is to analyze what types of stocks do well at various points surrounding bear market declines in the U.S. since 1926.


Since we are sitting at tail end of a severe bear market, the most pertinent portion of this study is what types of stocks perform well for the one- to three-year period following bear markets. For an investor trying to build a portfolio with good downside protection without sacrificing upside potential, the behavior of various types of stocks following bear markets is interesting and important information to understand.

This paper will begin by outlining the nine U.S. bear markets since 1926 and discuss what sorts of stocks performed well during and after those markets. During the nearly nine months since the March 9th market bottom, market trends have closely mirrored those of other severe bear markets. If history continues to repeat itself, the lessons from this study could prove to be extremely valuablefor the next two years.
