Our investment discipline is to align our outlook with current, measurable, observable market conditions – particularly valuations and market internals – and to change that outlook as conditions change. In prior market cycles across history, one could also respond immediately to “overvalued, overbought, overbullish” market extremes, which provided a kind of “limit” to speculation even before market internals deteriorated explicitly. Amid speculation driven by zero interest rate policies, speculation lost its “limits,” and we abandoned our bearish response to overextended syndromes except in periods when market internals are also unfavorable. It’s the striking uniformity of hostile conditions – extreme valuations, unfavorable market internals, and a preponderance of overextended syndromes, that prompts an interim comment.
Measured from the January 2022 market peak, the total return of the S&P 500 lagged behind the return of Treasury bills through April of this year. Meanwhile, our own measures of valuations and market internals have remained unfavorable. With the market seeming to skate by the trap door of extreme valuations and unfavorable internals without consequence, the push to new highs in the past few weeks has created the impression of a runaway advance.
As I noted in late-2021, there are certain features of valuation, investor psychology, and price behavior that tend to emerge when the fear of missing out becomes particularly extreme and the focus of speculation becomes particularly narrow. Last Friday, we hit a fresh “motherlode” of these conditions. Since the mid-1980’s, I’ve developed and collected scores of interesting syndromes and relationships that help to gauge overextended conditions, in both directions. I’ll occasionally add, discard, or tweak one or two, but for the most part, I’ve used the same set for years. The most important change in 2021 was to require deterioration in our gauge of market internals, regardless of how overextended conditions might be otherwise.
We keep the specifics of market internals and many technical measures proprietary, but we’re very open about the general features. A red flag is typically some combination of: overextended valuations and price/volume behavior; lopsided sentiment or speculative positioning; and divergence among individual stocks, industries, sectors, or security-types such bonds or lower-grade credit. The chart below shows the current tally of overextension syndromes, in weekly data. The blue line is the S&P 500 (right scale). The thin blue lines indicate periods when at least 30% of these syndromes were active.
In recent months, I’ve expanded the set of comparable syndromes we monitor in daily data, including downside compression syndromes, which I’ve periodically discussed in special updates over the years. The red bars show a tally of technical factors – mainly featuring overextended market action coupled with divergent internals – that are often present at intermediate market peaks. The green bars show technical factors, mainly compression syndromes, that are often present at intermediate lows. The blue line is the S&P 500 (left scale)
At present, the “last straw” of market action that deserves monitoring in daily data relates to “leadership.” Expansion in the number of stocks hitting fresh 52-week lows (even 2.5-3% of issues traded) amid new highs in the major indices, tends to be a feature of market exhaustion. The reason is the same one I noted approaching the 2007 market peak:
I continue to view the market advance of recent months as an attempt to “grasp the suds of yesterday’s bubble” rather than a new, durable bull market advance. I also believe that the S&P 500 could lose something on the order of 50-70% over the completion of this cycle, simply to bring long-term expected returns to run-of-the-mill norms that investors associate with stocks. Yet as I also note in nearly every market comment, typically with the word “emphatically,” nothing in our investment discipline relies on any forecast of near-term market action, nor on a reversion of valuations to their long-term historical norms.
The chart below shows our most reliable valuation measure: the ratio of nonfinancial market capitalization to corporate gross-value added, including estimated foreign revenues. The present level exceeds the 1929 and 2000 extremes, and indeed every point in U.S. history except those closely surrounding the early 2022 peak. Even the more conventional (but less reliable) S&P 500 price/forward operating earnings multiple is at levels that have no rivals except surrounding the 2000 and 2022 peaks. Put simply, my impression is that the period since early-2022 comprises the extended peak of one of the three great speculative bubbles in U.S. history.
The S&P 500 has enjoyed average annual nominal total returns of nearly 7.3% since 2000. That outcome represents 4.3% from nominal revenue growth, plus an average dividend yield of 1.9%, plus an extra 1.1% annually, achieved by driving the S&P 500 price/revenue multiple from its 2000 extreme of 2.2 to the even more extreme level of 2.8.
That’s how the math works. Price = Price/Revenue x Revenue. Shake those two ingredients. Add dividends. Chill and serve. Since 2000, investors have squeezed more return from 4.3% revenue growth plus 1.9% dividends only by driving the price/revenue multiple to record extremes. Now move valuations the other direction, and the retreat in valuations acts as a subtraction to long-term returns. The math is the same for any other valuation multiple you prefer. It’s just noisier for fundamentals like earnings, where much of that noise is driven by variation in profit margins – reflecting impermanent changes in interest costs and cyclical fluctuations in real unit labor costs.
Clearly, nothing requires investors to demand historically normal long-term returns. Assuming continued nominal revenue growth of 4.3% annually and adding the current S&P 500 dividend yield of 1.4%, a “permanently high plateau” in valuations implies estimated long-term expected S&P 500 nominal total returns of about 5.7% annually. Probably needless to say, I view that estimate as wildly optimistic, particularly based on how history has disabused the notion of a “permanently high plateau.”
With our most reliable valuation measures between 2.8 and 3.2 times their historical norms, even briefly touching those norms a decade from today would subtract between 9.8-11.0% annually from that 5.7% baseline, implying total returns in the range of -4.1% to -5.3% annually. Again, this is just arithmetic. Even a slight retreat from a “permanently high plateau” would be enough to pull 10-year estimated total returns into the low single digits. At current valuation extremes, it is almost unfathomable how much the popularity of passive investing and the expectation of satisfactory long-term stock market returns relies on the assumption of permanently high and ever-increasing valuations.
Meanwhile, if one expects higher returns to result from nominal growth due to unchecked inflation, it’s useful to examine the behavior of valuations during inflationary periods, both in the U.S. and elsewhere. In general, stock prices durably benefit from high inflation only after valuations have been driven to depressed levels. At present, the Consumer Price Index would have to triple for the positive impact of inflation on nominal fundamentals to outweigh the likely negative impact of rapid and sustained inflation on valuations.

Finally, a note on the “innovation” story that encourages investors to believe “This time is different,” as it has in every speculative episode in history. As Business Week wrote in 1929, “This illusion is summed up in the phrase ‘the new era.’ The phrase itself is not new. Every period of speculation rediscovers it.” Amid wild extrapolations from every corner, a few observations may provide a useful reality check:
1) The largest driver of margin expansion in recent decades has not been technological innovation but falling interest rate costs, temporarily locked in by massive refinancing in 2020 and 2021;
2) The growth rates and operating margins of mega-cap glamour stocks are not fixed numbers but trajectories.
3) Long-term, economy-wide growth is, and has always been, driven by innovation and productivity, with companies at the cutting edge enjoying initially high profits and growth rates that experience recurring cycles of creative destruction as the new industries expand.
4) If total S&P 500 revenues and U.S. GDP have averaged real annual growth of less than 2.5% annually for the past 30 years, even with the benefit of all that innovation (they have), and one can demonstrate that the increase in corporate profit margins during that period is largely tied to lower interest costs (one can), it is a mistake to value the entire market at record multiples just because some of the companies enjoy network effects that give them the ability to hoard market share. The cash flows are just concentrated in fewer hands.
5) Network effects and near-monopoly can slow and defer the erosion of profit margins, but they don’t eliminate longer-term competition (every fallen mega-cap in history teaches that).
Our own investment discipline is to respond to market conditions as they change over time. The adaptations we introduced in 2021 encourage an aggressive outlook (I was frequently leveraged, for example, in the early-1990’s) or a constructive outlook (possibly with position limits or safety nets) in about two-thirds of historical periods, and over half of periods since the 2009 market low. Constructive market conditions will emerge soon enough, if only locally and sporadically at first. We do not observe those conditions here at all.
