Japan's benchmark Nikkei 225 index enters trading on November 2 after closing at 63,290.11 on October 30, down 1,369.36 points, or 2.12%, in its final session of October, as selling in artificial intelligence and semiconductor-related stocks raised concerns about the sustainability of the technology-led rally, while investors prepared for a shortened trading week dominated by corporate earnings, monetary policy developments and the US midterm elections.
