The Stock Market Economy

 | Nov 15, 2018 01:10AM ET

Currently, some market watchers have begun to openly question whether the bull market in stocks has finally come to an end. They certainly have cause to worry. Valuations are frothy after a record run-up in the last few years. Bond yields across the yield curve are rising sharply, as the Fed Funds Rate breaks into territory not seen since before the market crash of 2008. Much higher costs of capital are already putting pressure on rate-sensitive industries such as housing and autos. The boost to earnings provided by the corporate tax cuts will fade and rising prices resulting from past monetary policy and import tariffs may be expected to slow consumption and take a toll on balance sheets. All this points to possible lackluster performance, with stocks essentially flat so far this year.

But even while many expect a difficult period for stocks, we must come to grips with the fact that generations of investors have come and gone who have not experienced a grinding and protracted bear market. Such a scenario is unthinkable given the narrative to which these investors have been exposed. But the page may about to be turned and there are reasons to believe that the bill may finally be coming due.

Falling interest rates are generally regarded as good for stocks. Not surprisingly then, since Treasury bond yields began falling in 1982 (based on data from U.S. Dept. of Treasury), stocks have trended higher. The memorable declines that we have had since then, the Black Monday Crash of 1987, the sell off after the ’90 recession, the Dotcom and September 11 implosion of 2000-2001, and the Crash of 2008, were really just interludes in an otherwise surging bull market that has risen more than 30 times in nominal terms, according to data from the World Bank. In those events, the brunt of selling happened quickly and was over before investors really knew what had happened.

In ’87, a 35% drop in the Dow occurred in just 3 months, from August to October. In ’90 an 18% fall, also in 3 months, again from August to October. In ’98, the Russian economic crisis pushed the Dow down 18% in a month, from July to August. In all these instances, stocks made new highs within two years of the initial drop, in August ’89, April ’91 and January ’99, respectively. Entering the current century, the more difficult pullbacks have occurred, but were manageable nevertheless. Beginning in January 2000, the Dow dropped 35% over a period of 33 months. It then took an additional 4 years to make fresh nominal highs. In October 2007, the Dow began falling and plunged 53% in 16 months. But after that, stocks climbed steadily and made fresh highs almost exactly four years after the bottom. (Yahoo!Finance, DJIA interactive charts)

Those who assume that these cases represent the worst-case scenarios of what we could see in the future are ignoring the brutal bear market that lasted 16 years between January 1966 and August 1982. While the nominal point drop of 18% during that time was not particularly bad, the move downward was memorable by its duration and the degree to which it was made far worse by inflation, which often approached double digits during that time.

Inflation-adjusted real values of stocks fell by a shocking 70% from 1966 to 1982. (Macrotrends Dow Jones 100 Year Historical Chart) Let that sink in. Over 16 years, the real value of stocks fell by almost three quarters! And it’s not like investors found refuge in bonds, which were also falling at that point due to the ravages of inflation and increased government borrowing. (10-year Treasury bonds hit nearly 16% in September 1981). (FRED Economic Data, St. Louis) Given how much stock and bond prices were falling in real terms, it’s surprising that the real economy didn’t implode along with it. Yes, GDP was generally sub-par during the stagflation “Malaise Days” of the 1970’s, but real GDP was positive in all but four years between 1966 and 1982, and growth averaged 2.95% over the entire period. (That’s higher than the 2.85% GDP growth has averaged since 1983). (based on data from the Bureau of Economic Analysis) That’s fairly impressive given the performance in the stock and bond markets.

Our relatively good fortune was made possible by the fact that the market was not nearly as important to the economy then as it has become now. Back in 1966, when the market had hit a peak (after a bull run that began in the early 1950’s) (Macrotrends Dow Jones 100 Year Historical Chart), by using the Dow Jones Index’s relationship to GDP from 1966 to 1971, the year when data begins for the Wilshire 5000, we estimate that the Wilshire 5000 (the broadest measure of the U.S. stock market) would have had a collective market cap of approximately 42% of GDP, meaning that stocks were worth less than half of the whole U.S. economy. Over the next 16 years, inflation pushed up the value of just about everything consumers bought…gas, clothing, movie tickets, medical services, etc. But stock valuations lagged significantly. As a result, by 1982 the collective valuation of the stock market was only 18% of GDP. (based on data from FRED Economic Data, St. Louis)
