Veteran investor Jeremy Grantham has expressed concerns that the current valuation of the U.S. stock market, which he estimates to be at 235% of GDP, is the highest ever recorded. He draws parallels to the tech bubble of 2000, referencing the Buffet indicator that signals when market valuations become dangerously inflated.
Grantham cautions that while the timing of a potential market peak is uncertain, the long-term outlook for U.S. stocks appears bleak, similar to historical lows. He also commented on SpaceX's recent IPO, suggesting that the enthusiasm surrounding AI investments could lead to excessive valuations, much like the dot-com era.
Grantham believes that SpaceX's valuation may be viewed historically as a peak moment in the market, indicating a potential for a significant correction ahead
