US Stocks at Most Expensive Relative to Bonds Since Dotcom Era
U.S. equities have reached their highest valuation relative to government bonds in over two decades, raising concerns among investors about the sustainability of this trend. The recent surge in stock prices, particularly among megacap technology companies, has pushed the forward earnings yield of the S&P 500 index down to 3.9%, according to Bloomberg data. Meanwhile, a sell-off in U.S. Treasuries has driven 10-year bond yields up to 4.65%. This shift has resulted in the equity risk premium—the additional return investors expect for holding stocks over bonds—falling into negative territory, a situation not seen since the dotcom boom and bust in 2002.
Ben Inker, co-head of asset allocation at asset manager GMO, commented on the current market sentiment, stating, “Investors are effectively saying ‘I want to own these dominant tech companies and I am prepared to do it without much of a risk premium.’” This attitude has raised alarms, as many analysts label the current market conditions as the "mother of all bubbles." The high valuations are attributed to fund managers seeking exposure to the robust growth of the U.S. economy and corporate profits, particularly among the so-called "Magnificent Seven" tech stocks.
Despite concerns about market concentration, some investors remain optimistic, believing that owning these dominant companies is essential for future growth. Inker noted that clients are expressing mixed feelings, with worries about market concentration alongside a desire to invest in leading tech firms.
The traditional equity risk premium, often referred to as the "Fed model," compares stock earnings yields to Treasury yields. Critics of this model, including Cliff Asness of AQR, argue that using Treasury yields as a benchmark is flawed and that the equity risk premium is not a reliable predictor of stock returns. Some analysts now prefer to compare stocks' earnings yields to inflation-adjusted bond yields, which also indicate that the equity risk premium is at its lowest level since the dotcom era, though not negative.
Aswath Damodaran, a finance professor at NYU, emphasizes the importance of using cash flow expectations and payout ratios to calculate the equity risk premium. He notes that while the premium has declined over the past year, it remains positive.
Market observers are raising red flags about the current valuation landscape. Chris Jeffery, head of macro at Legal & General’s asset management division, points out the significant disparity in pricing between U.S. equities and non-U.S. equities, suggesting that caution is warranted.
Goldman Sachs’ senior equity strategist Ben Snider acknowledges that while U.S. stocks' price-to-earnings multiples are high relative to historical norms, they may still be justified given the current economic environment. Goldman’s model indicates that the S&P 500 is aligned with its fair value, supported by ongoing earnings growth.
The current state of U.S. equities, characterized by high valuations relative to bonds, presents a complex picture for investors. While some see opportunities in the dominance of major tech companies, others caution against the risks associated with market concentration and the potential for a correction. As the market navigates these dynamics, the interplay between stock prices, bond yields, and investor sentiment will be critical in shaping the future landscape of U.S. equities. The ongoing debate about the sustainability of these valuations underscores the need for a diversified investment approach, particularly in a market increasingly driven by a handful of dominant players.
