Cyclically Adjusted Price-to-Earnings (CAPE) ratio
The Cyclically Adjusted Price-to-Earnings (CAPE) ratio, also known as the Shiller P/E ratio, is a valuation metric used to assess whether a stock market is overvalued or undervalued relative to historical norms. It was developed by economist Robert Shiller and is used to evaluate long-term investment opportunities across global stock markets.
Unlike the traditional Price-to-Earnings (P/E) ratio, which compares a company’s stock price to its recent earnings, the CAPE ratio smooths out earnings fluctuations by using inflation-adjusted earnings over a 10-year period. This helps account for economic cycles, reducing the impact of short-term volatility in profits.
The CAPE ratio is considered a useful measure for predicting long-term stock market returns rather than short-term movements. Historically, high CAPE ratios have been associated with lower future returns, while low CAPE ratios have signaled stronger returns.
