S&P 500 CAPE Ratio Tops 40, Matching Dot-Com Peak

The S&P 500 Shiller CAPE ratio exceeds 40, signaling valuations comparable to the late 1990s bubble era.
Key points
- The S&P 500 Shiller CAPE ratio is above 40, exceeding the historical average of 18.
- A fourth consecutive year of double-digit returns would match a streak last seen in the 1990s.
- Historical bear markets last 409 days with 36% losses, compared to 1,866-day bull runs.
The S&P 500 Shiller CAPE ratio has climbed above 40, a level last seen during the dot-com bubble. This valuation metric now sits more than double its historical average of 18, indicating extreme market pricing.
If the index maintains double-digit gains in 2026, it will mark four consecutive years of such returns. This streak matches a pattern not observed since the late 1990s, according to data cited by yahoo.com.
Valuation Levels Match Historical Peaks
Historical data shows the CAPE ratio peaked at 44 in the late 1990s before a major crash. A similar sharp rise occurred in the late 1920s, preceding one of the worst financial downturns in history.
Current pricing suggests the market is the most expensive it has been since the dot-com era. This leaves little room for error if corporate earnings fail to meet high investor expectations.
Bull Market Resilience Persists
The market has shrugged off sticky inflation, geopolitical conflicts, and rising oil prices. It even absorbed the Federal Reserve's first interest rate hike in three years without a significant sell-off.
Investors view the current phase as the end of the initial AI research period. Analysts expect a global rollout phase to drive further growth, potentially outpacing the previous expansion cycle.
Strategic Positioning for Volatility
Research from Charles Schwab indicates bull markets last an average of 1,866 days. During this period, the S&P 500 typically rises by 180 percent, far outweighing bear market losses.
Bear markets last only 409 days on average, with a typical 36 percent decline. Experts advise staying invested rather than attempting to time the market, as historical data shows long-term gains persist through short-term corrections.
