TOKYO - Tokyo stocks diverged on August 6, with the Nikkei 225 closing at 65,683.26, down 617.18 points, or 0.93%, as selling in artificial intelligence and semiconductor-related heavyweights outweighed broad gains across the wider market. On August 6, the broader market remained resilient, but the Nikkei was pulled lower by its heavy exposure to semiconductor equipment, chip testing, AI investment and data-center infrastructure names. Advantest weakened as chip-testing shares remained exposed to profit-taking after their sharp rebound. The yen remained steadier than in late July but still central to market psychology. Any concern over debt, asset sales or investment returns could again pressure the Nikkei because of SoftBank’s large index weight.
