CAPE Ratio Hits 42.2, Highest Level Since Dot-Com Bubble

The Shiller price-to-earnings (P/E) ratio, or CAPE ratio, stands at 42.2, reflecting the highest expense in the stock market in over 26 years. This level approaches the previous peak of 44.2 recorded in November 1999 during the dot-com bubble. The average CAPE ratio since 1990 is just over 27, highlighting the current market's high valuation. This trend has implications for investors as it suggests potential market volatility similar to past patterns, particularly given the influence of the AI boom on stock valuations.
