Tech Stocks Decline as Samsung's Earnings Miss AI Expectations, Raising Bubble Fears

U.S. stock futures indicated renewed weakness in technology shares, particularly chipmakers, after Samsung Electronics Co.'s earnings failed to meet lofty AI expectations. Samsung's stock slumped 7.7% despite a significant surge in operating income and doubled revenue in the last quarter. This development has fueled concerns about a potential AI bubble, with investors questioning whether the substantial investments in AI chips and data centers can generate sufficient productivity and profit gains to justify the valuations.
