Tokyo stocks ended mixed Thursday, as selling of artificial intelligence- and semiconductor-related shares weighed on the benchmark Nikkei stock index, while buying of shares in companies that posted strong earnings supported the broader market.
The 225-issue Nikkei Stock Average fell 429.23 points, or 0.7 percent, from Wednesday to close at 60,819.36.
The broader Topix index, meanwhile, finished 7.94 points, or 0.2 percent, higher at 3,937.33.
Both indexes rose in the morning session, with buying of AI- and chip-related stocks continuing after a strong quarterly report from major U.S. data center operator CoreWeave Inc. revived confidence in AI spending, analysts said.
But selling of those shares picked up in the afternoon, dragging the tech-heavy Nikkei into negative territory.
The Topix rose for a fourth straight trading session, supported by investors turning to relatively undervalued domestic-demand stocks and to shares of companies reporting robust earnings.
