Stock Market Sets New Record, But History Suggests Caution

The S&P 500 has reached a new milestone, surpassing 7,750 for the first time in U.S. stock market history. This achievement is a testament to the stock market's resilience and strength, but it also raises concerns about the market's valuation. The S&P 500 Shiller CAPE ratio, a widely followed metric that measures the market's valuation by smoothing earnings multiples using a 10-year moving average and adjusting earnings for inflation, has reached a record high. This has sparked worries among investors, as history suggests that high valuations can be a predictor of market downturns.

Why High Valuations Are a Concern

The S&P 500 Shiller CAPE ratio has been higher than it is now only once before - in late 1999 and early 2000. This was a time when the dot-com bubble was bursting, and the stock market tanked. Some investors believe that the market is in an AI bubble now, which could lead to a similar outcome. The rapid rise of the CAPE ratio is also a cause for concern, as it has spiked to record highs in the past, including in 1929, 2000, and 2021. The 1929 and 2000 market plunges are particularly notable, as they were preceded by high valuations.

But Could This Time Be Different?

While history suggests that high valuations can be a predictor of market downturns, there are some factors that could suggest that this time is different. Earnings are growing significantly faster than stock prices, which could make the surging S&P 500 Shiller CAPE ratio less frightening. As of August 28, 2026, with 97% of S&P 500 companies having reported second-quarter 2026 results, 86% reported a positive earnings per share (EPS) surprise, and 77% reported a positive revenue surprise. The S&P 500's earnings grew by 52%, which is a robust growth rate.

What Should Investors Do?

Investors may find themselves in a quandary, as a sky-high S&P 500 Shiller CAPE ratio has been a reliable predictor of market downturns in the past, but S&P 500 earnings are growing so briskly that there appears to be more room for stocks to run. Warren Buffett's approach to investing, which involves being highly selective and watchful, could be a useful strategy for investors. Buffett and his successor, Greg Abel, continue to be highly selective in how they deploy Berkshire Hathaway's massive cash stockpile, but they are nonetheless finding some attractive stocks to buy.

Conclusion

The stock market's new record high is a testament to its strength and resilience, but it also raises concerns about the market's valuation. While history suggests that high valuations can be a predictor of market downturns, there are some factors that could suggest that this time is different. Earnings are growing significantly faster than stock prices, which could make the surging S&P 500 Shiller CAPE ratio less frightening. Investors should be cautious and consider alternative investment opportunities, such as the 10 best stocks for investors to buy now, which could produce monster returns in the coming years.
