Cyclically Adjusted Price-to-Earnings (CAPE) Ratio

The Cyclically Adjusted Price-to-Earnings (CAPE) ratio is a valuation measure that adjusts the traditional P/E ratio by using average inflation-adjusted earnings over a 10-year period. This helps smooth out fluctuations in profits caused by economic cycles and provides a more accurate long-term view of a company's or market's value. The CAPE ratio is often used by investors to assess whether a market is overvalued or undervalued.

Example

If the CAPE ratio for the S&P 500 is significantly higher than its historical average, it may suggest that the stock market is overvalued and could be due for a correction.
