Artificial intelligence and semiconductor stocks traded lower before Friday’s opening bell as weakness in Japan’s technology sector and fresh competition from Chinese AI developers weighed on investor sentiment. <\/p>\n

Japan’s Nikkei <\/a>225 dropped 4.03%, marking its steepest weekly decline since April 2025, while the broader Topix lost 2.72%. Technology shares led the retreat, with memory maker Kioxia falling nearly 16%, while Tokyo Electron and Advantest declined about 8% and 7%, respectively. <\/p>\n

In U.S. premarket trading, Nvidia (NASDAQ:NVDA<\/a>) fell about 2%, Advanced Micro Devices (NASDAQ:AMD<\/a>) and Cerebras (NASDAQ:CBRS<\/a>) each lost around 3%, while Micron Technology (MU) slipped nearly 2%. Western Digital (NASDAQ:WDC<\/a>) and Seagate Technology (NASDAQ:STX<\/a>) declined about 3%, and Taiwan Semiconductor Manufacturing (NYSE:TSM<\/a>) dropped nearly 4% despite reporting stronger-than-expected quarterly results a day earlier. <\/p>\n

Meanwhile, Alibaba-backed Moonshot AI introduced Kimi K3, which it described as a 2.8 trillion-parameter open-weight AI model designed to compete with leading U.S. systems. The launch underscores growing competition from Chinese AI developers as investors assess the outlook for AI-related semiconductor companies. <\/p>\n","protected":false},"excerpt":{"rendered":"This article first appeared on GuruFocus.
