The Stock Market Is Echoing a Warning From the Dot-Com Bubble, and History Says Investors Should Make This 1 Move

The S&P 500 has gained 100% over four years driven by AI enthusiasm, but the Buffett indicator—which measures total U.S. stock market value relative to GDP—has reached a historic high of 238%, surpassing dot-com bubble levels of 148%. This suggests stocks are overvalued relative to economic fundamentals. However, history shows that despite past market declines following similar peaks, the market has always recovered and delivered long-term gains, suggesting investors should maintain positions rather than sell.
