The U.S. Equity Risk Premium (ERP): A Sign of Overvalued Stocks or Just Market Cycles?

The divergence between U.S. stocks and bonds has raised alarms among some market analysts, particularly regarding the U.S. equity risk premium (ERP). As the ERP reaches historically low levels—some even claim it's the lowest in 25 years—investors are questioning whether stocks are becoming overvalued relative to Treasuries. The ERP is calculated as the difference between the S&P 500 earnings yield and the 10-year Treasury yield, typically offering investors a premium for holding equities over "risk-free" government debt. In normal market conditions, this premium should remain positive.

However, we're far from "normal" times. As the Federal Reserve begins cutting interest rates, long-term bond yields are soaring, driven by persistent inflation and concerns over U.S. fiscal policy, especially rising debt levels. Meanwhile, the hype around artificial intelligence (AI) and the "U.S. exceptionalism" narrative—primarily pushed by a handful of Mega Cap tech stocks—has driven stock valuations to unprecedented levels, further exacerbating the disparity.

As a result, the ERP has been shrinking and even turning negative in some instances. If the 10-year Treasury yield continues to climb, the ERP could shrink even more, suggesting that stocks might look increasingly expensive compared to bonds.

So, does this mean it's time for investors to shift their portfolios away from equities and into Treasuries? While the extreme valuation of stocks is concerning, historical trends and other macroeconomic factors should be considered before making such decisions.
