Veteran investor Jeremy Grantham has a history of accurately predicting major market crashes, including:
1. The dot-com bubble (2000)
2. The global financial crisis (2008)
3. Japan’s asset bubble (1989)
Now, Grantham warns that the U.S. stock market is in a massive bubble, which could lead to a sharp 50% decline before stabilizing at reasonable levels. Even Warren Buffett, known for his long-term investment strategy, has indicated concerns about the market's overvaluation.
If history is any guide, investors should brace for turbulence ahead.
