Micron Technology falls 6% on China supply concerns and AI memory bandwidth bottlenecks, dragging tech-heavy Nasdaq lower.
The Nasdaq Composite slipped 0.61% midday Monday, weighed down by declines in memory chip stocks. Micron Technology led the losses, dropping 6% after reports suggested potential competition from Chinese suppliers and highlighted a growing gap between AI compute power and memory bandwidth. The Dow Jones Industrial Average rose 0.24%, while the S&P 500 edged down 0.33%.
Micron’s warning at the Hot Chips 2026 conference underscored an industry-wide challenge: AI compute power is advancing at three times the rate of memory bandwidth every two years, creating a bottleneck. The report of possible U.S. approval for Apple to source chips from China added to pressure on memory stocks. Nvidia, set to report earnings Wednesday, fell 2.1%, contributing to the Nasdaq’s decline.
The broader market reaction was mixed, with investors assessing the implications of China-related supply shifts and AI infrastructure constraints. Tech-heavy indices bore the brunt of the selling, while the Dow’s modest gains reflected sector rotation.
