Amkor Technology IncAmkor plunged nearly 24% after its Q3 revenue guidance missed estimates.
Semiconductor stocks including Lam Research, Monolithic Power Systems, Marvell Technology, Micron, and onsemi fell sharply amid a broad global sell-off driven by fears of increased Chinese competition and doubts about the sustainability of AI-related demand. Lam Research dropped 6.5%, Monolithic Power Systems fell 3.5%, Marvell Technology declined 7.4%, Micron lost 8.4%, and onsemi slid 5%. The declines were part of a wider rout that saw Amkor plunge nearly 24% after its third-quarter revenue guidance missed estimates, while Vishay Intertechnology, FormFactor, and Penguin Solutions fell roughly 9% to 11%. Investor anxiety was heightened by reports of China's progress in advanced chip manufacturing, including mass production of homegrown immersion deep ultraviolet lithography machines and the strong stock market debut of Chinese competitor ChangXin Memory Technologies, sparking fears of future memory chip oversupply and pricing pressure.
