The CAPE measure is described elsewhere by Barry Ritholz:
CAPE looks at the prior 10 years of trailing earnings. It smooths out any given quarters’ ups and downs, and theoretically includes a full business cycle. The way Shiller intended it to be used was to create a valuation metric that would suggest whether stocks are likely to outperform their average returns over the next 10 years.
The “q” is ‘Tobin’s q” which is the ratio between the market value and replacement value of the same physical asset. Here it is over the long term:
That’s expensive. But it can always get more so!
