Japanese Stocks Plunge Third-Most in History on AI and Chip Fears

Tokyo's Nikkei index recorded its third-largest single-day point decline in history as investors dumped technology shares en masse over concerns about the outlook for artificial intelligence and semiconductors.

The selloff centered on stocks seen as beneficiaries of the AI boom, putting heavy pressure on the index and driving it sharply lower during the session. The move reflected investor caution amid uncertainty over the growth trajectory of the semiconductor industry and high-tech companies.

Details on the specific point decline and the stocks that weighed most heavily were not fully disclosed in initial information.
