CAPE 10 Ratio: Understanding, Calculation, and Real-World Insight
SB
Summary:
The P/E 10 ratio, also known as the cyclically adjusted price-to-earnings (CAPE) ratio or Shiller PE ratio, is a valuation measure for equities that employs real per-share earnings over 10 years. This article delves into its definition, historical significance, calculation method, and potential limitations.
The P/E 10 ratio: Understanding the basics
The P/E 10 ratio, popularized by Nobel laureate Robert Shiller, evaluates equity indices using real per-share earnings over a decade. This valuation metric employs smoothed earnings, eliminating fluctuations caused by variations in profit margins over a typical business cycle.
Origins of the P/E 10 ratio
Yale University professor Robert Shiller, renowned for his book “Irrational Exuberance,” introduced the P/E 10 ratio as a warning signal during the late-1990s U.S. stock market rally, predicting a bubble. The ratio’s roots trace back to Benjamin Graham and David Dodd’s 1934 “Security Analysis,” recommending multi-year averages to address illogical P/E ratios influenced by business cycle fluctuations.
Calculating the P/E 10 ratio
The P/E 10 ratio involves several steps. Start with the annual earnings per share (EPS) of an equity index over the past decade. Adjust these earnings for inflation using the consumer price index (CPI). Average these real EPS figures over the 10 years. Finally, divide the current level of the index by the 10-year average EPS to obtain the P/E 10 ratio or CAPE ratio.
Historical variation and significance
The P/E 10 ratio exhibits significant historical variation. Data from “Irrational Exuberance” indicates a range from a low of 4.78 in December 1920 to a high of 44.20 in December 1999. As of August 2020, the historic P/E 10 average was 17.1. This variability plays a role in predicting investors’ likely returns over the next two decades, according to Shiller and John Campbell.
Shortfalls of the P/E 10 ratio
While a powerful indicator, the P/E 10 ratio has faced criticism. It may not always accurately signal market tops or bottoms. For instance, in July 2011, the S&P 500’s CAPE ratio suggested a 40% overvaluation. However, conventional valuation measures, like the P/E, portrayed a less bearish view. The article explores such instances and the limitations of relying solely on this ratio for market analysis.
Pros and cons of the P/E 10 ratio
Real-world examples of P/E 10 in action
Examining historical scenarios where the P/E 10 ratio played a pivotal role can offer practical insights for investors. For instance, during the 2008 financial crisis, the P/E 10 ratio signaled that the market was significantly overvalued, providing a warning to astute investors who adjusted their portfolios accordingly. In contrast, looking at periods of economic recovery might showcase the ratio’s ability to guide investors towards potentially undervalued assets.
Application in sector analysis
While the P/E 10 ratio is often associated with broad equity indices, its application extends to sector-specific analysis. Investors can utilize this ratio to assess the relative valuation of sectors within the market. Understanding how different sectors perform in relation to their historical P/E 10 averages can provide valuable insights into sector rotation strategies and help identify areas of potential opportunity or risk.
