This suggests that stocks are currently expensive and Company XYZ may be overvalued. When evaluating the stock market, it’s always important to consider a variety of factors, not just one metric. Always consult with a financial advisor before making any major investment decisions.
- Investors walk away with a clearer depiction of the P/E ratio, and a more realistic benchmark for valuing a stock.
- It also suggests that comparison of CAPE values can assist in identifying the best markets for future equity returns beyond the US market.
- For example, if a company’s stock price is $100 and its earnings per share over the past 10 years have averaged $10, then its CAPE ratio would be 100/10, or 10.
- Neither of these two ratios are perfect, but both of them are useful, which is why I always look at them together.
- The previous occurrences were before the stock market crash of 1929 and before the bursting of the dot-com bubble.
- Over time, the Federal Reserve used different theories to set interest rates.
This metric was developed by Robert Shiller and popularized during the Dotcom Bubble when he argued (correctly) that equities were highly overvalued. For that reason, it’s also casually referred to as the “Shiller PE”, meaning the Shiller variant of the typical price-to-earnings (P/E) ratio of stock. Hence, companies that are barely profitable often exhibit P/E ratios so high that usage of the metric is not informative. But by no means does the high P/E ratio necessarily signal that the company in question is currently overvalued by the market. The CAPE ratio most often serves as a market indicator, so the share price refers to the market price of a stock market index. 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.
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 ratio is generally applied to broad equity indices to assess whether the market is undervalued or overvalued. While the CAPE ratio is a popular and widely-followed measure, several leading industry practitioners have called into question its utility as a predictor of future stock market returns.
What is the CAPE ratio?
As can be seen, during periods where the CAPE ratio of the S&P 500 became rather high, returns over the next decade and more were invariably rather poor. For instance, Benjamin Graham recommended the necessity to use an average of past earnings in his book, Security Analysis. While many financial analysts lauded the creation of the Shiller P/E ratio, it gained even more notoriety when it correlated with both the Dot-Com Bubble and the Great Recession. While it’s far from a crystal ball, the CAPE ratio is nonetheless a proven tool in benchmarking the financial health of companies and markets. However, you also know that the CAPE ratio is not a perfect predictor of market return forecasts. So you have to use other accounting principles to make an informed decision.
The CAPE ratio for the S&P 500 index is considered one potential indicator of a future stock market crash. There has been a correlation between market crashes and the CAPE ratio. However, critics believe the CAPE measure has little predictive value. Since no one knew who was really in charge, stock prices were volatile. The chart shows wide swings in the CAPE ratio were normal at that time.
CAPE ratio by country: how to find and use global stock valuation data
Sometimes the U.S. market is a bargain, while other times it’s overvalued. Sometimes other countries are extremely cheap, while sometimes they are expensive. I also regularly analyze the cash flows of companies on the market to determine their fair price and to see how many companies are trading above what their cash flows imply they should trading signals software be trading at. As the 2016 research study pointed out, though, the markets of Sweden and Denmark underwent major structural changes during that time. Denmark had nearly double the earnings growth as the US had, their number of index companies decreased from 20 t0 11, and the healthcare sector went from 10% of the index to 60% of the index.
The difference between the Shiller P/E ratio and the traditional P/E ratio is the time period covered in the numerator, as we mentioned earlier. While there is significant criticism (and controversy) surrounding the methodology by which inflation is measured, the Consumer Price Index (CPI) remains the most common measure of inflation in the U.S. In practice, the use-case of the CAPE ratio is to track broad market indices, namely the S&P 500 index.

Shiller and Campbell expounded on Benjamin Graham’s aggregate average concept with a practical method of calculating earnings-per-share over the course of an entire economic cycle. Together, the two published a book called Valuation Ratios and the Long-Run Stock Market Outlook. This text not only outlined the CAPE ratio, it also provided applied examples of the ratio for S&P 500 earnings going back to 1872. You then compare this to the current level of CAPE for the US stock market, which is 32.
For long-term investors, one of the most important benchmarks to consider is the value of a company vs. what it’s trading for. Many investors use P/E as a quick metric for understanding relative value; however, the CAPE ratio might be a more accurate way to gauge whether a stock is over- or under-valued. descending triangle pattern And while looking back isn’t always the best solution for making forward-looking predictions, the CAPE ratio provides aggregate data that’s an effective means to benchmarking a company’s value. Analysts and investors need a sense of the average to evaluate if certain metrics fall above or below it.
CAPE Ratio (Shiller PE Ratio): Definition, Formula, Uses, Example
The CAPE ratio allows the assessment of a company’s profitability over different periods of an economic cycle. The ratio also considers economic fluctuations, including the economy’s expansion and recession. Essentially, it provides a broader view of a company’s profitability by smoothing out the cyclical effects of the economy. AQR, one of America’s great quant firms, is said to mark up the CAPE by around 10% to get what it considers the best real-time estimate. That’s because the CAPE only increases past profits for inflation, not for “real” gains usually tied to economic growth.
The table below lists the historical and current CAPE ratios of the largest equity markets in the world. Among the largest economies, the most expensive stock markets can be found from India, the U.S. and Japan. However, the CAPE ratios of different markets should not be directly compared to each other. The best way to evaluate if a country’s stock fundamental forex trading market might be undervalued or overvalued is to compare the nation’s current ratio to its historical average. To understand the Shiller P/E ratio you first have to understand the price-to-earnings ratio. 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).
While this is certainly possible, it’s important to remember that no one can predict the future with 100% accuracy. The current CAPE ratio for the US stock market is around 32, which is well above its long-term average of 16. Most traditional stock market prediction models can explain less than 20% of the variation in future stock market returns. So we may consider the Shiller-PE one of the more reliable forecasting tools available to practitioners. It’s not about big portfolio moves, or relying heavily on any given metric. It’s about gradual, small moves, and taking into account numerous valuation metrics and multiple long-term research examples of why they’re relevant and what they can tell us about forward returns.

Calculating the Shiller P/E ratio can also be a minefield, since Generally Accepted Accounting Principles (GAAP) have a tendency to change over time. As GAAP rules change, so do the factors that account for a company’s earnings. Going back 10 years to gather EPS and adjusted earnings may skew the ratio.
The chart shows that the right level of CAPE changes as Fed policy changes. The CAPE ratio is one of the ways to measure what stocks are worth. Moderate inflation generally leads to higher prices for stocks. We don’t know if inflation targeting is ultimately the best policy.
That chart is logarithmic so the visual difference is smaller than it really is. Investing in the S&P 500 would have returned 962% from 1993 to 2018. Investing in the cheapest 25% of countries based on CAPE ratios would have returned 3,052%, or more than three times as much.
Taking these swings into account can help show whether a company will perform in the long run and is worth investing in. The CAPE ratio is a popular way of assessing how long-term business cycles impact a company’s valuation. Discover the difference between the CAPE ratio and P/E ratio, and how to calculate the CAPE ratio for stocks and indices.
