Key takeaways
- The value of value relative to growth is back to historic highs, being driven by the extreme concentration of the top seven stocks in the S&P 500 Index.
- The combination of expanding equity multiples and higher interest rates in 2023 has overshadowed growing risks and created an environment reminiscent of 1987’s “Black Monday.”
- Value provides investors strong advantages in the face of these growing extremes, offering the potential for downside protection against market declines as well as compelling relative return potential on a decrease in market concentration.
One of the things our process is designed to identify is unsustainable extremes we can exploit, particularly when investor behavior prices either too much optimism or pessimism into equity valuations. Right now, the market continues to confidently price in a soft economic landing and the continued dominance of US mega cap growth stocks. We believe this zealous optimism has overshadowed the growing risks posed by a dangerous combination of rising equity multiples and increasing interest rates.
Today, we have anything but a uniformly priced market. It is bearish for US indexes, while providing a great opportunity to look for mispriced stocks with strong fundamentals beyond the concentrated top of those indexes. The value of value relative to growth is back to historic highs, being driven by the extreme concentration of the top seven stocks in the S&P 500 Index (Exhibit 1). Never has so much liquidity been sucked into so few stocks, and the risk may prove a black hole for capital and weigh on returns due to increased volatility from higher correlations.

The correlation of the big seven bet is also elevated (Exhibit 2), especially compared to the rest of the market that is enjoying relatively low pairwise correlations. We are also observing an extremely low correlation between value and growth styles, which argues strongly for diversifying any US cap-weighted index bets with value (Exhibit 3).

The key observation is that indexes are positioned for extremely low uncertainty, reflecting a soft landing and a near-term growth boost from artificial intelligence (AI). However, what we see is that concentration in the market is being driven almost entirely by a spike in valuation multiples, despite the continued rise in real rates and the cost of capital. This is not sustainable unless interest rates come down in a benign soft-landing manner, or growth dramatically accelerates.
This combination of rising equity multiples and a significant increase in interest rates has also created the third outlier that we’ve observed: Extreme risk potential reminiscent of 1987’s “Black Monday” market crash. Between January and August 1987, equity valuation multiples increased approximately 25%. Conversely, over the same period, effective interest rate multiples (a valuation multiple derived from the difference between the initial and current yield to illustrate the attractiveness of a risk-free bond) decreased by approximately 30%. In 2023, year-to-date equity valuation multiples have expanded 39% while effective real yield multiples have declined almost 29%, a reality that is being overlooked in favor of soft-landing optimism. While we are certainly not forecasting such an event on the horizon, the similarities are too great to be ignored.
Value stocks continue to offer investors strong advantages in the face of these growing extremes, and we believe now is the best time to bet against expensive risks in highly concentrated US indexes. Value stocks remain close to the cheapest levels they have ever been relative to historically concentrated long-duration growth assets and have arguably never been better index insurance. As a result, value investors have the tools to not only possibly protect capital in the event of a market decline, but also the potential to realize compelling relative returns on any decrease in the current extreme levels of market concentration.
We believe we are well positioned for another surprise to consensus expectations, which should help the equity market become a little less extreme. In the meantime, we are comfortable waiting for such a reversal as low correlations between value and growth can smooth the ride.
Definitions
The S&P 500 Index is an unmanaged index of 500 stocks that is generally representative of the performance of larger companies in the US.
October 19, 1987, known as “Black Monday,” was a day of infamy on Wall Street, when steep and unexpected selloffs devastated global markets.
WHAT ARE THE RISKS?
Past performance is no guarantee of future results. Please note that an investor cannot invest directly in an index. Unmanaged index returns do not reflect any fees, expenses or sales charges.
Equity securities are subject to price fluctuation and possible loss of principal. Fixed-income securities involve interest rate, credit, inflation and reinvestment risks; and possible loss of principal. As interest rates rise, the value of fixed income securities falls. International investments are subject to special risks including currency fluctuations, social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. Commodities and currencies contain heightened risk that include market, political, regulatory, and natural conditions and may not be suitable for all investors.
US Treasuries are direct debt obligations issued and backed by the “full faith and credit” of the US government. The US government guarantees the principal and interest payments on US Treasuries when the securities are held to maturity. Unlike US Treasuries, debt securities issued by the federal agencies and instrumentalities and related investments may or may not be backed by the full faith and credit of the US government. Even when the US government guarantees principal and interest payments on securities, this guarantee does not apply to losses resulting from declines in the market value of these securities.
