What is the Shiller CAPE Ratio?
The Shiller CAPE Ratio, also known as the cyclically adjusted price-to-earnings (P/E) ratio, is a valuation measure created by Nobel laureate Robert Shiller. It's designed to provide a more accurate picture of stock market valuations by smoothing out the impact of economic cycles.
The CAPE Ratio is calculated by dividing the current level of the S&P 500 index by the average inflation-adjusted earnings of the index over the past 10 years. This methodology helps to remove the volatility caused by economic cycles, giving investors a clearer view of the market's long-term valuation.
