Shiller CAPE ratio nears 41 as S&P 500 up 78% in three years
The Shiller cyclically adjusted price-to-earnings ratio has risen to nearly 41, a level far above the historic average of 17.8 and approaching values not seen since the dot-com bubble burst. This indicator suggests that current stock prices are overvalued relative to 10 years of inflation-adjusted earnings.

The current bull market has seen significant gains over the past three years. The S&P 500 is up 78%, the Nasdaq Composite has surged 99%, and the Dow Jones Industrial Average has risen 53%. Despite these broad index increases, market performance is heavily concentrated in artificial intelligence stocks. While the S&P 500 is up 17% over the past year, four in 10 stocks in the index have actually declined during that period.
No one knows when a bear market will occur, and a single financial metric cannot perfectly predict a sell-off. However, the high CAPE ratio and the concentration of returns in specific sectors serve as warning signs for potential market instability. Investors seeking to prepare for downturns often look to long-term strategies involving diversified funds like the Vanguard S&P 500 ETF (VOO). This fund provides exposure to all market sectors, including technology, energy, industrials, and consumer goods.
The S&P 500 has returned an average of 10.5% annually since 1957. While future returns are not guaranteed, this historical track record indicates that staying invested allows participants to benefit from bull markets. Research from J.P. Morgan based on 20 years of market data supports this approach. The investment bank found that seven of the ten best days in the market occurred within two weeks of the ten worst days.
Investors who remained in the market and captured those best days achieved total returns more than double those who missed them over the two-decade period. This data highlights the risk of withdrawing funds during downturns. The primary lesson for long-term investors is to maintain their positions through bear markets to avoid missing the recovery days that drive overall index gains.
