Chip stocks experienced a broad decline, with HUA HONG SEMI (01347) dropping 5.37% to HK$96.9 and GIGADEVICE (03986) falling 4.34% to HK$291.2 at the time of writing. SMIC (00981) decreased by 3.85% to HK$66.1, while SHANGHAI FUDAN (01385) was down 3.76% to HK$46.08. The downturn was influenced by Advanced Micro Devices (AMD), which closed down 17.31% on Wednesday, marking its largest single-day drop since May 2017. AMD's Q4 FY2025 report revealed record quarterly revenue exceeding $10 billion, maintaining a year-over-year growth rate above 30%, with EPS growth slowing but still beating analyst estimates by nearly 16%. However, some analysts expressed concerns, noting that while AMD reported better-than-expected revenue and profit figures, its guidance for the first quarter fell short of market expectations. Following AMD's significant decline, the "big four" in memory storage also saw collective losses overnight, with SanDisk dropping 15.95% and Micron Technology falling 9.55%. On February 5th, Japanese and South Korean stock markets opened lower, with chip stocks tracking the overnight slump in U.S. tech shares; Samsung Electronics and SK Hynix both declined over 4%, while SoftBank Group's stock plunged more than 6%.
