Japan's Nikkei index experienced a significant downturn, dropping 1.8% to close at 50,376.53 points. The decline was primarily driven by a sell-off in artificial intelligence (AI) related stocks, reflecting broader concerns about valuations in the tech sector.

This movement suggests a shift in investor focus towards companies demonstrating strong financial performance, potentially indicating a broader market rotation.

Global AI Valuation Concerns

Market Drivers

The rally was primarily fueled by positive developments in the United States, where the Senate has made progress on measures to reopen the government after a 40-day shutdown. This news sparked hope among investors, leading to a broad-based rally in the Japanese market.

Technology stocks led the gains, with several key players seeing substantial increases:
