S&P 500 Shiller CAPE Ratio hits 40 as bond yields reach 2002 highs
The S&P 500 Shiller CAPE Ratio has risen to just over 40, a level close to the dot-com era record of 44 and significantly above its long-term average of 17. This valuation metric, which measures the index's 10-year inflation-adjusted earnings, signals elevated prices as the current bull market enters its fourth year. The S&P 500 is up more than 15% over the last six months, while the Nasdaq Composite has surged nearly 20% in the same period.

Long-term bond yields have recently reached their highest levels since 2002, with both the 10-Year and 30-Year Treasury yields soaring to multi-decade highs. Rising yields increase borrowing costs for mortgages and credit cards, which can reduce consumer spending and slow economic growth. Oil prices have also contributed to economic pressure, with Brent crude oil futures trading at around $106 per barrel, up by more than 55% since the beginning of the year due to the ongoing war in Iran.
Higher energy prices are keeping inflation above the Federal Reserve's 2% target. The Fed raised interest rates in September, and CME Group's FedWatch tool indicates an 88% probability of another rate hike by the end of the year. Additional rate hikes could disproportionately impact tech companies, as hyperscalers have spent hundreds of billions of dollars on data centers. A slowdown in AI build-out due to higher borrowing costs could affect the broader market, particularly because the S&P 500 is market-cap-weighted.
The 10 largest companies account for around 40% of the S&P 500's total value. Many of these firms, including Nvidia, Amazon, and Microsoft, are investing heavily in artificial intelligence. This concentration means that a decline in tech stocks could drag down the rest of the market. While no indicator can predict when a downturn may begin, history suggests that long-term investment in the S&P 500 has consistently yielded positive results.
According to Crestmont Research, the S&P 500 has ended each rolling 20-year period since 1919 with positive total returns. The index has survived major events such as the dot-com bubble, the Great Recession, and the COVID-19 crash. Despite this volatility, the S&P 500 is up by more than 766% since early 2000. This historical performance underscores the potential for long-term gains despite short-term volatility.
