Citigroup believes that the stock gains driven by the artificial‑intelligence boom could continue for some time. “The AI bubble isn’t over yet” said Dirk Willer, Citigroup’s senior economist and head of macroeconomics and asset‑allocation, on the “Handelsblatt Invest” podcast on Wednesday.
Willer, a veteran Wall Street analyst who witnessed the dot‑com bubble in early 2000s New York, is convinced that this time will also see market exaggerations. “The more impressive the technology, the more people will over‑invest” he explained.
Given the hefty AI spend by large U.S. tech giants, it is understandable that investors want to diversify more aggressively. Still, Willer cautioned that if a tech bubble bursts, almost all assets could tumble downward.
