What is the CAPE Ratio? 🌟
The CAPE (Cyclically Adjusted Price-to-Earnings) ratio, developed by economist Robert Shiller, compares the price of a stock (or stock market index) to its average inflation-adjusted earnings over the last ten years. In other words, it’s a way to calculate how much you’re paying for a company’s long-term profit potential.
CAPE Ratio Formula: \[ \text{CAPE Ratio} = \frac{\text{Price per Share}}{\text{Average Inflation-Adjusted Earnings per Share (EPS, 10 years)}} \]
CAPE Ratio vs Price-to-Earnings (P/E) Ratio Comparison
| Feature | CAPE Ratio | P/E Ratio |
|---|---|---|
| Timeframe | Uses 10-year average earnings | Uses EPS from the most recent year |
| Adjustments | Inflation-adjusted | Not inflation-adjusted |
| Volatility | Smoother, less volatile due to averaging | Can be more sensitive to market fluctuations |
| Use | Long-term market valuation | Short-term valuation |
| Interpretation | Indicates long-term market trends | Indicates current market sentiment |
Examples
-
Example 1: If a stock is priced at $100 and its average inflation-adjusted EPS over the last ten years is $5, then: \[ \text{CAPE Ratio} = \frac{100}{5} = 20 \] Meaning you’re paying 20 times the average annual profit.
-
Example 2: For a stock priced at $200, with a 10-year average EPS of $10: \[ \text{CAPE Ratio} = \frac{200}{10} = 20 \] Same CAPE ratio, but context matters!
