David Rosenberg Warns US Stock Market Is Dangerous Bubble

David Rosenberg, founder of Rosenberg Research & Associates Inc., warned that the United States stock market is currently the most dangerous he has seen in his 40-year career. He characterized the market as a bubble, citing extreme valuations, leverage, and investor positioning.

Rosenberg argued that the current bull market depends more heavily on artificial intelligence advancements than the technology sector did before the dot-com bubble. He stated that the United States is the epicenter of a technology boom for which investors are overpaying.

In response to these risks, Rosenberg has shifted his portfolios away from US stocks and toward Treasuries and overseas equities.
