Global stock markets experienced a substantial rally as renewed confidence in artificial intelligence (AI) returned to the market. This surge was primarily driven by Micron Technology Inc.'s impressive financial results and optimistic forecast. The positive sentiment was widespread, impacting various markets globally.
The semiconductor sector, a key beneficiary of the AI trend, saw significant gains. The VanEck Semiconductor ETF rose 5% in US premarket trading. Individual companies within the sector also saw strong performance, with Western Digital Corp. jumping 12%, Sandisk Corp. climbing 12%, and Seagate Technology Holdings PLC adding 8.3%. This indicates that investors are increasingly recognizing AI's role in driving rapid profit growth for chipmakers.
The renewed AI confidence also had a pronounced impact on Asian markets. Japanese and South Korean equities climbed, with the tech sector leading the gains. Japan's tech-heavy Nikkei 225 Stock Average rose as much as 3%, with chip tester manufacturer Advantest Corp. being among the top performers. The broader Topix index increased by 1.1% as of 10:10 am Tokyo time. In South Korea, the Kospi index surged by 6% at one point, with SK Hynix Inc. rallying on its plans for a U.S. listing.
This widespread stock rally underscores the market's sensitivity to developments in the AI sector. Micron's performance provided a crucial signal that the AI trade remains robust and capable of driving significant market movements. The market's positive reaction suggests that investor enthusiasm for AI-driven growth is rekindled, leading to substantial gains in related industries and global stock indices.
