An Unsustainable Equilibrium

Callout

The S&P 500 stands at the most extreme level of valuations in history. As I detailed in August, our most reliable valuation measures – based on their relationship with actual subsequent S&P 500 total returns across a century of market history – suggest that the expectations of investors for long-term market returns are wildly misaligned with the returns implied by discounted cash flows.

The chart below shows our most reliable gauge of market valuations in data since 1928: the ratio of nonfinancial market capitalization to gross value-added (MarketCap/GVA). Gross value-added is the sum of corporate revenues generated incrementally at each stage of production, so MarketCap/GVA might be reasonably be viewed as an economy-wide, apples-to-apples price/revenue multiple for U.S. nonfinancial corporations.

To be clear – this is not a price chart. It’s a valuation chart. It aligns precisely with the happiest and most satisfying moment of a speculative bubble: the point where wildly misaligned expectations for market returns are being realized anyway – via self-fulfilling speculation. If you understand how a bubble works, this chart is both strikingly beautiful from a mathematical standpoint, yet utterly terrifying from an investment perspective.

The scatterplot below shows this same measure versus actual subsequent 12-year average annual S&P 500 nominal total returns. Recall how “errors” work – since a bubble peak features valuations that are vastly beyond historical norms, the market returns during the 12-year period leading up to that bubble peak are also vastly beyond the returns one would have expected based on the starting valuations at that time.

As I’ve detailed in prior comments, these “errors” are informative. Large positive “errors” over the trailing 12-year period are associated with dismal market returns over the subsequent 12-year period. This reflects the fact that the end of the trailing period and the beginning of the future period is a bubble extreme.

Cap/gross value graph

Just over a year ago, we introduced a hedging implementation that has already had a significant impact on our investment discipline, by allowing us to abandon any need for valuations to normalize. Frankly, I do expect the current speculative bubble to collapse, partly because history has always produced this outcome, and partly because I believe that investors have misconstrued the origin of the profits that they are celebrating with premium valuations. Still, nothing in our discipline requires the market to collapse, or to approach historical valuation norms ever again.
