A Perspective on Secular Bull and Bear Markets
Was the March 2009 low the end of a secular bear market and the beginning of a secular bull? Did we just witness a short secular bear?
Let's examine the past to broaden our understanding of the range of historical trends in market performance. An obvious feature of this inflation-adjusted series is the pattern of long-term alternations between uptrends and downtrends. Market historians call these "secular" bull and bear markets from the Latin word saeculum "long period of time" (in contrast to aeternus "eternal" — the type of bull market we fantasize about).
We've added the recent major downturn as a potential new secular bear and the February S&P 500 market top. Time will tell if this is in fact a secular bull, but note that the market is still at very high levels.
The key word on the chart above is secular. The implicit rule we're following is that blue shows secular trends that lead to new all-time real highs. Periods in between are secular bear markets, regardless of their cyclical rallies. For example, the rally from 1932 to 1937, despite its strength, remains a cycle in a secular bear market. At its peak in 1937, the index was 29% below the real all-time high of 1929. For a scholarly study of secular bear markets, which highlights the same key turning points, see Russell Napier's Anatomy of the Bear: Lessons from Wall Street's Four Great Bottoms.
An alternate view of secular trends is offered by Ed Easterling of Crestmont Research. See his fascinating study Understanding Secular Stock Market Cycles, which made a persuasive case that we remain in a bear market that began in 2000. The underlying principle, in Easterling's view, is the price/earnings ratio, which remains lofty. Ed maintains that even with the lofty market highs, the current cycle has been the best cyclical bull inside of a secular bear.
If we study the data underlying the chart, we can extract a number of interesting facts about these secular patterns (note that the table below includes the 1932-1937 rally):
Since that first trough in 1877 to the March 2009 low:
- Secular bull gains totaled 2075% for an average of 415%.
- Secular bear losses totaled -329% for an average of -65%.
- Secular bull years total 80 versus 52 for the bears, a 60:40 ratio.
This last bullet probably comes as a surprise to many people. The finance industry and media have conditioned us to view every dip as a buying opportunity. If we realize that bear markets have accounted for about 40% of the highlighted time frame, we can better understand the two massive selloffs of the 21st century.
