(Bloomberg View) — Yesterday, we discussed why the Standard & Poor's 500 Index has gone sideways for the past few months. The prime suspects were rich valuations, earnings crimped by falling energy prices and higher returns to be had overseas.
Today, I want to look at the Nasdaq Composite Index. It closed at 5,056.06 yesterday, surpassing its March 2000 dot-com high. It took more than 15 years to breach that earlier mark. Meanwhile, the Dow Jones Industrial Average and S&P 500 passed their pre-crisis 2007 highs almost two years ago.
The Nasdaq has been the laggard, and there are many questions about why. Does this represent the triumph of value investing over growth? Dividends over potential? Blue chips over sexiness? Or is something else going on?
The answer, in my humble opinion, lies in the nature of secular market cycles. Although we only have a century or two of data, markets seem to alternate between multi-decade booms and busts. Some analysts like to describe these as "secular." These are different from cyclical markets, which are shorter. The period from 1966 to 1982 was a secular bear market, just as the stretch from 1982 to 2000 was a secular bull market. Compare that with the 74 percent rally that followed the plunged in 1973 — that was a cyclical bull market within a secular bear market.
These are more than arbitrary definitions. Secular markets typically reflect the dominant economic and sociological themes of their eras. Consider the post-War World II period, or the inflationary malaise of the 1970s or even the roaring 1980s and 1990s. Each of these periods can be defined by way of a generational, overriding idea. These were all significant secular market cycles.
I look at three key questions when trying to identify secular markets: First, are markets stuck in a trading range, or are they breaking out to new highs? Second, where are valuations? (This cycle, heavily influenced by Federal Reserve policies, has forced us to add the phrase "relative to alternatives.") And third, are price-earnings multiples expanding or contracting? How much investors are willing to pay for a dollar of earnings says a lot about the collective psychology.
Which brings us back to the issue of the Nasdaq. Why did it take 15 years for the tech-heavy index (though not as tech heavy as it once was) to make new highs?
The short answer is how stock-market bubbles pull gains into the present from the future. Toward the end of a secular cycle, the crowd becomes aroused and starts paying attention. Collectively, they begin to recognize how much money has been made during the past few years, and how much of the move they missed. So the crowd begins to pile in, somewhat late in the cycle and at somewhat elevated valuations. Inevitably, they do worse than those who were early to the show. If humans were a rational species — and my experiences on this planet decidedly suggest otherwise — they would pay a reasonable price for risk investments such as equities. Markets discount future cash flow; a modest model suggests some sensible multiple of profits as a fair price to pay for a stock. Indeed, when we look at the history of investing, we see surprisingly regular mean reversion when it comes to prices paid relative to earnings. When stocks as a group are purchased at a very high multiple, the expected returns drop a lot; when they are purchased inexpensively, expected returns rise. A P/E ratio of 15 is about the historical average.
