The Buffett Indicator, a key measure of U.S. stock market valuation, has reached an unprecedented level of 223%-224%, with some reports indicating it could be as high as 230%. This surpasses previous peaks, including the dot-com bubble's 150% and the post-pandemic high in 2021. Historically, the indicator's long-term average has been between 80%-100%, with 100%-120% considered a normal valuation range. The indicator, favored by Warren Buffett, suggests that U.S. stocks may be significantly overvalued at current levels.
