Cyclically Adjusted PE ratio

The CAPE ratio is used to analyze a publicly held company's long-term financial performance while considering the impact of different economic cycles on the company's earnings.

The CAPE ratio is similar to the price-to-earnings ratio and is used to determine whether a stock is over-or under-valued.

The ratio considers the impact of economic influences by comparing a stock price to average earnings, adjusted for inflation, over a 10-year period.
