Introduction
Understanding the valuation of the stock market is crucial for investors to make informed decisions. One of the most significant tools for assessing stock market valuations is the Cyclically Adjusted Price-to-Earnings Ratio (CAPE Ratio), often referred to as the Shiller PE Ratio. This article delves into the CAPE Ratio, its significance, and how it can be used to gauge the current valuation of the US stock market.
Understanding the CAPE Ratio
The CAPE Ratio is a valuation ratio that smooths out the earnings of a company over several years. It's calculated by dividing the current price of a stock by the average inflation-adjusted earnings per share (EPS) over the past ten years. The formula is as follows:
CAPE Ratio = Current Stock Price / Average Inflation-Adjusted EPS over 10 Years
The rationale behind using a 10-year period is that it provides a more accurate reflection of the long-term profitability and sustainability of a company's earnings. The CAPE Ratio is named after the renowned economist Robert Shiller, who popularized this metric.
Significance of the CAPE Ratio
The CAPE Ratio is considered one of the best measures to assess whether the stock market is overvalued or undervalued. A CAPE Ratio above 20-25 is typically considered to indicate that the market is overvalued, while a CAPE Ratio below 10-15 suggests undervaluation.
Historical Context:
- Overvalued: During the dot-com bubble of the late 1990s, the CAPE Ratio skyrocketed to around 43, indicating an overvalued market.
- Undervalued: During the 2008 financial crisis, the CAPE Ratio fell to around 13, indicating an undervalued market.

Using the CAPE Ratio as a Forecasting Tool
While the CAPE Ratio is an excellent tool for assessing current market valuations, it can also be used as a forecasting tool. By analyzing the historical performance of the CAPE Ratio, investors can make educated guesses about the future direction of the market.
- Historically, when the CAPE Ratio has been above its long-term average of around 16, the market has tended to experience negative returns over the following ten years.
- Conversely, when the CAPE Ratio has been below its long-term average, the market has tended to experience positive returns over the following ten years.
Conclusion

By understanding the historical context, significance, and application of this metric, investors can make more informed decisions about their investment strategies. Whether you're a seasoned investor or just starting out, it's crucial to pay attention to the CAPE Ratio and incorporate it into your investment analysis.
