The P/E ratio tells you whether a single company is undervalued or overvalued by comparing its stock price to its earnings per share (EPS). High P/E ratios generally signify a company is overvalued whereas low ones indicate it may be a good value buy with the potential for high future returns.

Robert Shiller demonstrated using 130 years of back-tested data that the returns of the S&P 500 over the next 20 years are strongly inversely correlated with the CAPE ratio at any given time.

The CAPE ratio, an acronym for cyclically adjusted price-to-earnings ratio, was popularized by Yale University professor Robert Shiller. The P/E ratio is a valuation metric that measures a stock’s price relative to the company’s earnings per share. CAPE ratio also known as cyclically adjusted price earnings ratio is used to measure stock market valuation to realize whether a stock is overvalued or undervalued. Being an investor, you are required to monitor the stock market regularly and be familiar with the financial ratios that provide a view of the market’s valuation over time.

The long term average smooths out short term volatility of earnings and medium-term business cycles in the general economy and they thought it was a better reflection of a firm’s long term earning power. The P/E 10 ratio is a valuation measure generally applied to broad equity indices that use real per-share earnings over 10 years. The P/E 10 ratio also uses smoothed real earnings to eliminate the fluctuations in net income caused by variations in profit margins over a typical business cycle. The P/E 10 ratio is also known as the cyclically adjusted price-to-earnings (CAPE) ratio or the Shiller PE ratio. The CAPE ratio is a valuation measure that uses real earnings per share (EPS) over a 10-year period to smooth out fluctuations in corporate profits that occur over different periods of a business cycle.

But when stocks are already expensive, and already have a high price-to-earnings ratio, they have a lot less room to grow and a lot more room to fall the next time there’s a recession or market correction. The cyclically-adjusted price-to-earnings (CAPE) ratio of a stock market is one of the standard metrics used to evaluate whether a market is overvalued, undervalued, or fairly-valued.
