Definition
The Cyclically Adjusted Price-to-Earnings Ratio (CAPE), also known as the Shiller P/E ratio, is a valuation measure that uses real earnings per share over a 10-year period to smooth out fluctuations in corporate profits that occur over different periods of a business cycle.
Formula
CAPE = Current Market Price / Average Real Earnings (10 years)
Where:
- Current Market Price = Current stock/index price
- Average Real Earnings = Inflation-adjusted earnings averaged over 10 years
