CAPE Ratio > Shiller P/E Ratio

The Shiller P/E Ratio helps investors understand whether the stock market as a whole is overvalued or undervalued. It is calculated as the current price divided by the average inflation-adjusted earnings per share (EPS) over the past 10 years.

We are currently in one of the most overvalued stock markets, with the Shiller P/E Ratio at 32.61, a level not seen since the late 1990s. During the dot-com rally of tech stocks in the US, the Shiller P/E Ratio reached 44.19. At that time, this high ratio suggested that the market was in a bubble. Are we now in an AI bubble?
