16-Year Slump? If So, Blame It on the Boomers
A new study of American demographic patterns and the stock market predicts that while the market may rally periodically, its overall direction will be downward until around 2018.
This bearish forecast is based on a model devised by three finance professors ? John Geanakoplos of Yale, Michael J. P. Magill of the University of Southern California and Martine Quinzii of the University of California at Davis. In a study titled "Demography and the Long-Run Predictability of the Stock Market" (
http://papers.ssrn.com /sol3/papers.cfm?abstract_id=329840), they report that their model has done a good job of explaining the bull and bear markets of the last century. But its accuracy as a forecasting tool, of course, is untested.
The professors' approach is complex, but it depends on a simple indicator: the ratio of the number of middle-aged people to the number of young adults in the population. When this ratio rises, the overall market's price-to-earnings ratio will rise, too, the professors predict. When the age ratio declines, as it is likely to do until about 2018, the market's P/E will also decline.
Demographics are the most important factor in determining long-term market trends, according to the professors, who believe that individual investment behavior largely depends on age-related patterns. Younger adults, those from 20 to 39, are generally consumers. Middle-aged people, 40 to 59, tend to invest in stocks. Retirees are likely to sell more stocks than they buy.
Market performance is strongly affected by the relative numbers of people in each of these three life stages, the professors say. When more people are entering middle age than retiring, for example, the market tends to rise because more people will be buying than selling. If the next generation of investors is smaller, the trend will reverse when the middle-aged investors retire.
The major influence of the next two decades will be the aging of the baby boomers, the approximately 79 million people born in the United States from 1945 to 1965. This generation has about 27 million more people than the one that preceded it, and about 10 million more than the one that followed.
The big difference in the sizes of these generations has already led to wide swings in the stock market, the study found. As the first baby boomers approached middle age in 1985 and began investing heavily, their buying more than offset the selling of the older generation then entering retirement. Stocks entered a multiyear bull market.
That trend is reversing, according to the model, which predicts that the market has entered a long decline caused by baby boomers selling stocks as they approach retirement. The sales will be only partially offset by the purchases of the smaller group entering middle age.
The model predicts that this long-term trend will not turn positive again until after 2018, when retirees' stock sales will be more than offset by the purchases of younger investors. This trend will strengthen as the larger baby boom "echo" generation, born between 1985 and 2005, enters middle age.
Since the professors began circulating their research as a working paper in August, critics have been skeptical that the model will apply to other periods or countries as it has to American history. Professor Magill is using it to study Japan, and so far it appears to hold up well. The model suggests that much of the long-running bear market there can be explained by the high ratio of retirees to middle-aged people.
To derive from the model a long-term forecast for the American market, it is necessary to estimate how fast corporate earnings will grow. Assuming that they grow at the same rate as they have over the last two decades, the model predicts that the market, after inflation, will lose more than half its value through 2018.
Still, the model holds out hope for truly long-term investors. After all, if the professors are right, a bull market lasting more than a decade will begin after 2018.
