Yardeni Research Warns of Elevated Market Valuations

The S&P 500 has surged 27% this year, hitting over 50 record closing highs. Fed rate cuts, strong earnings, and a Trump win have fueled the stock market rally. However, Yardeni Research has highlighted five charts that show the stock market is trading near extreme valuations.

“We wouldn’t like to see them go any higher because that would force us to raise the odds of a 1990s meltup scenario from our current subjective probability of 25%,” Yardeni Research said in a Tuesday note. The trailing 12-month price-to-earnings ratio surged to 27.1x in the third quarter. While it is not near its highest level ever, it is well above its long-term average of 19.6x.

The Buffett Ratio, which measures the total value of US stocks relative to nominal GDP, rose to a record high of 2.96x in the second quarter. Warren Buffett has previously indicated that when the ratio rises above 2.0x, it suggests the stock market is overvalued. The forward price-to-earnings ratio, based on forward-looking analyst estimates for corporate earnings, is nearing the peak seen during the stimulus-driven stock market rally of 2020 and 2021.

At 22.0x, the forward P/E ratio is close to the 25.0x record high reached during the dot-com bubble in 1999.

Extreme stock market valuations

The Federal Reserve’s stock market valuation model compares the forward earnings yield of the S&P 500 with the 10-year Treasury yield.

When the two yields converge, it can suggest the stock market does not have an attractive valuation. The spread between the S&P 500’s earnings yield and the CPI inflation rate is another valuation measure to monitor. This measure tends to be negative during economic recessions and bear markets.

Currently, it has been only slightly positive for the past six quarters and trending lower. Ultimately, valuation measures have proven to be poor market timing tools. There’s nothing stopping the stock market from getting even more expensive before its next bear market correction.

“Investors will pay a higher P/E the longer they believe that the economic expansion will last. That’s because time is money. The longer the expansion, the longer that earnings have to grow to justify the current multiple,” Yardeni Research said.

Market Momentum vs. Valuation Risks

Investors remain optimistic, but some experts see risks. Strong earnings and Fed policies fuel the stock market rally. However, history shows rapid gains often lead to corrections. High valuations can limit future returns and increase volatility.

Some analysts believe long-term growth justifies higher prices, while others warn of a potential bubble. Watching key indicators, like earnings growth and interest rates, can help investors navigate uncertainty. While stocks may climb higher, smart investing requires balancing optimism with caution.
