Tom Bilyeu Mentioned it

“There's something called the CAPE Index or the CAPE Ratio where you look at basically the average of, I think it's a 10-year stretch of the earnings that the company got compared to what they're being valued at, and that traditionally runs, I think the number is like 16x. We're now over 40.”

Scott Galloway Mentioned it

“The CAPE ratio — that's the price of the market divided by 10 years of company earnings adjusted for inflation. It's meant to smooth out spikes. The long run average is about 17. And right now it's 41. That's the second highest in 145 years.”
