Understanding the Shiller P/E Ratio

We don’t know if inflation targeting is ultimately the best policy. Put simply, the super-low and even negative real rates in recent years led to towering P/E multiples that the bulls wrongly assumed would endure. At the same time, profit margins hit virtually never-before-seen heights that also couldn’t last. The lift-off in real rates is what could easily pop the balloon. You may want to put a lot more faith in the math than in the bull scenario that’s likely to prove bull.

• Well I think you should be ready to ask for your money back (you won’t get it) if you try to use CAPE as a market-timing divining rod.
• The lift-off in real rates is what could easily pop the balloon.
• In the same way as the P/E ratio, a stock with a high CAPE ratio is considered overvalued, and a stock with a low CAPE ratio would said to be undervalued.
• The S&P 500 Shiller CAPE Ratio, also known as the Cyclically Adjusted Price-Earnings ratio, is defined as the ratio the the S&P 500’s current price divided by the 10-year moving average of inflation-adjusted earnings.
• Or you can use resources like Shiller’s Yale website, which already has done most of the heavy lifting for you.

The CAPE Ratio (also known as the Shiller P/E or PE 10 Ratio) is an acronym for the Cyclically-Adjusted Price-to-Earnings Ratio. The ratio is calculated by dividing a company’s stock price by the average of the company’s earnings for the last ten years, adjusted for inflation. The CAPE ratio is calculated by dividing a company’s stock price by the average of the company’s earnings over a ten-year period and adjusting it for inflation. However, critics of the P/E ratio argued that using just one year of profits couldn’t give an accurate representation of profits.

But those who have a financial background know that CAPE gives you a little more accuracy than the P/E Ratio. The Shiller PE ratio uses inflation-adjusted 10-year earnings data to minimize the impact of short-term earnings volatility and make long-term comparisons possible. The CAPE ratio is used to forecast the likely earnings of a company or index over the next 20 years. The theory is that the lower the value of the ratio, the higher the return from equities over the next two decades as the stocks come into line with their true value. And the higher the value of the ratio, the less likely equities are to achieve oversized returns, as their stock prices are inflated already.

The market capitalization is the price that investors in aggregate are paying for all shares of all public companies. In other words, whenever the CAPE ratio of the market is high, it means stocks are overvalued, and returns over the next 20 years will likely be poor. In contrast, whenever the ratio is low, it means the stocks are undervalued, and returns over the next 20 years will likely be good. This metric was developed by Robert Shiller and popularized during the Dotcom Bubble when he argued (correctly) that equities were highly overvalued.

Shiller P/E Ratio: How To Value The Stock Market

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 Shiller PE Ratio or CAPE – also known as cyclically adjusted price-to-earnings is a valuation indicator that helps investors & traders to understand whether the stock market (S&P 500) is undervalued or overvalued. The ratio is equal to how to buy fantom the Current Price of the SP 500 Index divided by the average inflation-adjusted Earnings of the S&P 500 over the prior 10 years. It can help them to identify whether stocks are currently overvalued or undervalued. However, it is important to remember that the CAPE ratio is not a perfect predictor of future stock market performance. But it’s important to remember that the CAPE ratio is not a perfect predictor of future stock market returns.

This site provides equity research and investment strategies to give you the insight and data you need for managing your money through all market conditions. 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 be trading at. As you’ll notice, the CAPE ratio and the Cap/GDP ratio correlate very closely, which further strengthens the case that the CAPE ratio is a reliable measure of market valuation. In recent years, many people have questioned whether the metric is still a viable way to measure market valuation.

What matters in calculating how many dollars investors will pay for each sawbuck in earnings isn’t the “nominal” but the “real” yield. Companies raise prices to cover their costs, so their revenues quantitative trading strategies should increase in tandem with relatively modest inflation. What’s punishing is a wide premium over and above the CPI that investors can get from purchasing bonds instead of stocks.

Don’t use CAPE to predict the markets

But by no means does the high P/E ratio necessarily signal that the company in question is currently overvalued by the market. 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.

S&P 500 Shiller CAPE Ratio (Cyclically Adjusted PE Ratio

The S&P 500 Shiller CAPE Ratio, also known as the Cyclically Adjusted Price-Earnings ratio, is defined as the ratio the the S&P 500’s current price divided by the 10-year moving average of inflation-adjusted earnings. The metric was invented by American economist Robert Shiller and has become a popular way to understand long-term stock market valuations. 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.

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. A high CAPE ratio indicates that stocks are expensive relative to earnings, while a low CAPE ratio indicates that they are cheap. For instance, Benjamin Graham recommended the necessity to use an average of past earnings in his book, Security Analysis. In economics, the term “inflation” is a measure of the rate of change in the pricing of goods and services within a country across a specified time frame. In the same way as the P/E ratio, a stock with a high CAPE ratio is considered overvalued, and a stock with a low CAPE ratio would said to be undervalued. If the P/E ratio figure is high when compared to other companies in the industry or an index – typically above 11 – then the stock is overvalued.

Average vs. Trends in Earnings Per Share (EPS)

At 32, its current level, CAPE is at the upper limit of its expected range. This was also a time when countries adhered to the gold standard. Policies under the Bretton Woods Agreement maintained relatively stable foreign exchange rates. Over time, the Federal Reserve used different theories to set interest rates. The chart below shows those theories matter to the CAPE ratio.

The real 10-year rate equals the yield on 10-year TIPS, or treasury inflation protected securities. The recent jump in the long bond has driven the TIPS rate to 2.37%, the highest number in 20 years, excluding a brief explosion in the GFC. TIPS offers folks and funds a return of 2.37% points over projected inflation, on totally safe bonds. That’s a lot of competition for stocks, which are anything but safe, and seldom riskier than right now.
