While it can be used to analyze individual stocks, the Shiller P/E ratio is generally applied to an entire stock market index, most often the S&P 500. When used in this fashion, the Shiller P/E ratio provides an accurate measure of the value of an entire stock index that smooths out the short-term earnings volatility experienced by its constituent companies. To understand why financial analysts use the Shiller P/E ratio, it’s important to look at the shortcomings of the regular price-to-earnings (P/E) ratio. As a quick refresher, you can calculate P/E by dividing share price by earnings per share (EPS). For instance, if the share price is $10 and the EPS is $1, the P/E is 10. The CAPE ratio is used to forecast the likely earnings of a company or index over the next 20 years.

Benchmarking the True Value of a Company
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. Value investors Benjamin Graham and David Dodd argued for smoothing a firm’s earnings over the past five to ten years in their classic text Security Analysis. Graham and Dodd noted one-year earnings were too volatile to offer a good idea of a firm’s true earning power. In a 1988 paper [5] economists John Y. Campbell and Robert Shiller https://www.broker-review.org/ concluded that “a long moving average of real earnings helps to forecast future real dividends” which in turn are correlated with returns on stocks. The idea is to take a long-term average of earnings (typically 5 or 10 year) and adjust for inflation to forecast future returns. 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.
Why is the CAPE ratio important for investors?
For example, some people have argued that changes in accounting rules have altered how we define corporate earnings, which can skew the current CAPE ratio measurement compared to how it was measured in the past. It’s applied worldwide to measure the valuation of markets across different countries, offering a lens through which investors can assess international investment opportunities. To imagine this in practice, consider a company whose adjusted earnings over the past ten years total $10 per share. It divides the current market price by the average inflation-adjusted earnings over the past decade. However, the CAPE ratio has been higher than 25 and even 30 since then in the mid-2010s and early 2020s, and we haven’t seen that kind of market crash.
- The CAPE ratio most often serves as a market indicator, so the share price refers to the market price of a stock market index.
- There is debate over how accurate the CAPE ratio is, especially when used with individual stocks.
- It has not been prepared in accordance with legal requirements designed to promote the independence of investment research and as such is considered to be a marketing communication.

How to calculate the CAPE ratio
It is often applied to leading stock market indices, such as the S&P 500 or individual stocks, as an indicator of potential overvaluation or undervaluation compared to the assumed intrinsic value. Shiller himself has proposed an alternative calculation based on recent changes in corporate payout practices. For example, many companies have moved toward share repurchases rather than dividends as a way to distribute cash to shareholders.

Since we want to buy when the P/E is low, this gives us a false signal that the market is expensive, that we shouldn’t buy, when indeed it’s the best time to buy. It’s most commonly applied to the S&P 500, but can be and is applied to any stock index. 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. It is a variant of the more popular price to earning ratio and is calculated by dividing the current price of a stock by its average inflation-adjusted earnings over the last 10 years. Unlike the traditional price to earnings ratio (P/E), the CAPE ratio attempts to eliminate fluctuations that can skew corporate earnings, i.e. “smoothen” the reported earnings of companies.
Economic conditions, growth rates, and inflation impact the CAPE Ratio differently across countries. As such, it’s essential to compare the ratio within the context of each country’s historical averages and current economic climate. While the traditional P/E Ratio offers a snapshot of price relative to the last year’s earnings, the CAPE Ratio extends this vision, smoothing out the impact of business cycles.
The most commonly-used one is called the Price-to-Earnings (P/E) ratio, which divides the price of a share of stock by the annual earnings per share of that stock. Normally, you want to buy a healthy and growing company when its shares are trading at a low P/E ratio, so you get plenty of earnings for the price you pay. Using average earnings over the last decade helps to smooth out the impact of business cycles and other events and gives a better picture of a company’s sustainable earning power. By considering the earnings of companies over a 10-year period, adjusted for inflation, the CAPE Ratio aims to provide a long-term perspective on market valuations.
The Shiller P/E ratio is a reliable measure of valuation when compared against the historic P/E ranges and averages of the same stock, as well as when compared to its industry, index, and close competitors. In bull markets, low P/E ratios are hard to find and primarily identified in more traditional and established companies in the sectors of commodities, energy, utilities, material, industrials, and consumer staples. However, the king of extremely high P/E ratios during bull cycles is the NASDAQ 100, which has an average P/E of 29.1, which is over 50% bigger than the DOW Industrial index.
This suggests that stocks are currently expensive and Company XYZ may be overvalued. Roughly speaking, in a market with a bullish horizon, higher P/E ratios are the norm, as investors’ expectation is for the earnings to grow in the short-medium term. Other research has suggested that using the Shiller P/E to forecast equity returns could yield overly pessimistic results based on changes in GAAP (generally accepted accounting principles) methods for calculating earnings. Professor Jeremy Siegel from the Wharton School of Business suggests that using operating earnings instead of GAAP earnings may enhance the predictive power of the Shiller P/E. Finally, using the CAPE ratio as a broad-market benchmarking tool can result in inaccuracies due to mega-cap companies.
