Tokyo stocks fall on AI doubts, earnings caution

Tokyo stocks fell Tuesday as skepticism about artificial intelligence-driven growth and caution ahead of the earnings season triggered broad selling pressure. The Nikkei Stock Average dropped 841.28 points, or 1.30 percent, to 64,075.42, while the Topix index fell 1.43 percent to 4,009.21. Selling of AI- and semiconductor-related shares continued following concerns over debt at U.S. data center operator CoreWeave Inc., with dip-buying limited before corporate earnings later this month. Rising oil futures due to Middle East tensions also weighed on sentiment, while financial shares declined on worries about tighter lending conditions. The U.S. dollar weakened slightly to the lower 158-yen range in Tokyo. Nonferrous metal, bank, and glass and ceramics issues led decliners on the top-tier Prime Market.
