The Buffett Indicator Just Hit an All-Time High. Here's What History Says Comes Next.

The Buffett Indicator, which measures total U.S. stock market value relative to GDP, has reached an all-time high of 230%, surpassing the 140% peak before the 2000 dot-com bubble. The extreme valuation is largely driven by concentration in the 10 largest companies, which now represent 35% of the S&P 500 and are heavily weighted toward AI stocks. While history suggests stretched valuations correlate with weaker long-term returns rather than immediate crashes, investors should maintain modest expectations and consider holding cash for more attractive opportunities.
