A new wave of caution is sweeping through global equity markets as investors reassess the durability of the artificial intelligence investment boom.
The shift marks a departure from the relentless buying that characterized earlier in the year, with market participants now focusing on the volatility inherent in the sector's rapid expansion.
The sentiment shift is being driven by a confluence of factors, including rising US Treasury yields and growing skepticism regarding the return on investment for massive AI infrastructure projects.
A prominent research firm recently issued a bearish warning on US equities, highlighting how higher borrowing costs could erode the profitability of capital-intensive tech firms.
This analysis suggests that the market's previous pricing of AI growth may have been overly optimistic, leaving portfolios exposed to a correction.
The concentration of AI exposure in global equity markets appears more severe than previously assumed, particularly outside the United States.
