This morning, the Dow Jones Industrial Average hit a new all-time high, as did the S&P 500. The news coverage seems to be split between those calling for even higher stock prices and those who are worried that a new bubble is forming.
In fact, it could be both.
If you think about it, it seems kind of strange that stocks are hitting new highs even as earnings have declined for several quarters in a row. It seems kind of strange, with risks in Europe rising as the EU struggles with Britain’s exit—and with China’s currency continuing to depreciate, raising risks there—that U.S. stocks are pushing higher. And it seems kind of strange, even as the world gets riskier and U.S. companies make less money, that investors are bidding up stock prices.
And yet, here we are. “It is what it is” is an overused phrase, but we can’t simply ignore what's happening. Stock prices are rising. So are valuations. We have to respect the reality of the situation and respond to it.
Why are valuations rising so much?
The justification for rising prices is twofold.
Risks are lower. First, although risks exist, they are actually lower than they have been. Europe and Britain seem committed to an amicable separation, for example, and China’s economy seems to be improving. U.S. company earnings are declining but look likely to grow over the next couple of quarters as the economy improves and headwinds subside. All good arguments and, frankly, ones I have made in the past.
But, as you can see in the chart below, they don’t explain the magnitude of the rise in valuations over the past couple of years.
This chart from yardeni.com, a great market analysis firm, shows that the price level of the stock market, expressed as the ratio of prices to expected earnings over the next year, is now very high, well above 2007 levels—at around 17x versus around 15x. Even accounting for the reasons to be cheerful mentioned above, that’s still a substantial gain over the previous peak, and one that cries out for an explanation.
Interest rates are lower, too. The explanation is the second reason U.S. stock prices have risen: low interest rates. As rates drop, the present value of any stream of earnings, even lower earnings, is worth more—and the valuation level goes up. According to this argument, with current record-low interest rates, we should see high valuation levels.
All well and good, but now we need to take the next step: why are interest rates so low? The answer is less cheerful. Interest rates are low because economic conditions are weak around the world. The U.S. is doing relatively well, which is why our interest rates are higher, comparatively speaking. But elsewhere, low rates are a sign of serious problems. In Europe, Japan, and many other areas, rates are signaling trouble ahead.
