In the ever-evolving landscape of the stock market, understanding valuation metrics is crucial for investors. One such metric is the Current CAPE Ratio (Cyclically Adjusted Price-to-Earnings Ratio), which provides a long-term perspective on stock market valuation. This article delves into what the CAPE Ratio is, how it's calculated, and its implications for the US stock market.
What is the CAPE Ratio?
The CAPE Ratio, also known as the Shiller P/E Ratio, is a valuation tool that adjusts the standard P/E Ratio for the business cycle. While the traditional P/E Ratio compares the current market price of a stock to its trailing 12-month earnings, the CAPE Ratio takes into account the average inflation-adjusted earnings over the past 10 years. This adjustment helps smooth out the fluctuations caused by economic cycles and provides a more accurate assessment of stock market valuation.
How is the CAPE Ratio Calculated?
The formula for the CAPE Ratio is straightforward:
CAPE Ratio = Current Price of the Stock / (Average Inflation-Adjusted Earnings Over the Past 10 Years)
To calculate the average inflation-adjusted earnings, the historical earnings per share (EPS) of the stock are divided by the Consumer Price Index (CPI) to adjust for inflation. The 10-year average of these adjusted EPS figures is then used in the formula.

Case Studies: CAPE Ratio in Action

Let's consider a hypothetical case to illustrate the impact of the CAPE Ratio on investment decisions. Assume the CAPE Ratio for the US stock market is 25. In this scenario, the market is overvalued, and a rational investor may decide to take a cautious approach or look for undervalued sectors or individual stocks.
On the other hand, if the CAPE Ratio is 15, indicating an undervalued market, an investor may seek opportunities in growth sectors or companies with strong fundamentals.
