The cyclically adjusted price/earnings ratio (CAPE) made famous by Yale University finance professor (and Nobel laureate) Robert Shiller.
The CAPE currently stands at 36.6 for the S&P 500.
That’s higher than 98% of monthly readings since 1881, and more than double the 140-year average, suggesting an extremely overvalued market.
Mark Hulbert MarketWatch 3 May 2021
The cyclically adjusted price-to-earnings ratio made famous by Robert Shiller at over 22 times, this measure of earnings is still uncomfortably above the long-term average.
it is a handful of technology and consumer discretionary stocks that have lifted the overall valuation of the US market. The top 10 stocks in the S&P 500 trade at a forward price-to-earnings ratio of 31 times on average.
When you strip out these stocks, the forward PE comes down to under 20 times.
/Chart showing this is also historically high/
