The Shiller P/E is calculated by dividing the daily stock price by the multi-year inflation adjusted earnings, E10. Here we use a similar calculation for individual companies. When we calculate today's Shiller P/E ratio of a stock, we use today's price divided by E10.

The dividend discount model (DDM) is one of the most basic of the absolute valuation models. The dividend discount model calculates the "true" value of a firm based on the dividends the company pays its shareholders.

What is a good PE ratio to buy stocks?

Regular PE Ratio
The highest peak for the regular PE ratio was 123 in the first quarter of 2009. By then the S&P 500 had crashed more than 50% from its peak in 2007. The PE ratio was high because earnings were depressed.
Shiller PE Implied Market Return

Excess CAPE Yield (ECY)
As the Shiller PE keeps increasing, Dr. Robert Shiller recently introduced a new metric called the Excess CAPE Yield,” or ECY, to give a more precise picture of the stock market. ECY is calculated by the inverse of Shiller PE, which is really the Shiller’s earning yield, subtracted by the U.S.
Investment Strategies at Different Market Levels
The Shiller PE and the ratio of total market cap over GDP can serve as good guidance for investors in deciding their investment strategies at different market valuations. Historical market returns prove that when the market is fair or overvalued, it pays to be defensive.
How Is the CAPE Ratio Used?
Many investors, traders, and economists use the ratio when forecasting market conditions. Not only is the ratio used to determine the state of the market as a whole, but it can also be used to determine the state of an individual asset like a stock or ETF. Here are a few examples:
What Is the Significance of 10 Years of Data?
The primary driver of the ratio’s stability is the fact that it measures the data over the course of a 10-year moving average, rather than measuring real earnings for this year in comparison to the current price.
Historic and Current Readings
Although there has been plenty of debate surrounding the efficacy of the Shiller P/E ratio in predicting market crashes, the metric does appear to have flashes of warning signs before several market crashes throughout history. For example:
Final Word
Although there are plenty of people who argue against the Shiller P/E ratio as a predictor of future market movements, there’s no arguing the fact that its readings were significantly high prior to most major market crashes throughout recent history.
The Shiller PE
Robert Shiller first proposed a ten year timeframe for his CAPE ratio, targeting it towards the S&P 500 - the most well known American stock index. Subsequently, CAPE has been adapted for a number of other countries and indexes.
Sources of the Shiller PE and CAPE Ratio Calculator
Thank you to Robert Shiller, for providing his monthly data on the S&P 500. Please see his site for an explanation of the calculation of the ratio.
Updated CAPE Ratio Chart
This is a chart that I update regularly based on raw data from Shiller’s website.
Why the CAPE Ratio is Important
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.
Limitations of the CAPE Ratio
In recent years, many people have questioned whether the metric is still a viable way to measure market valuation.
Final Words
I pay attention to CAPE and Cap/GDP closely, as well as other valuation metrics, because it helps inform my investment decisions.
Interpretation
The price earnings ratio is calculated by dividing a company's stock price by it's earnings per share. In other words, the price earnings ratio shows what the market is willing to pay for a stock based on its current earnings. It is one of the most widely-used valuation metrics for stocks.
Interpretation
Instead of dividing by the earnings of one year (see chart above), this ratio divides the price of the S&P 500 index by the average inflation-adjusted earnings of the previous 10 years. The ratio is also known as the Cyclically Adjusted PE Ratio (CAPE Ratio), the Shiller PE Ratio, or the P/E10.
