Asian semiconductor stocks tumbled Thursday, as a sell-off in U.S. chipmakers spilled into the region, with SK Hynix continuing to see massive volatility since its U.S. listing last week. <\/p>\n
Shares of SK Hynix tumbled over 9% in Seoul, reversing the previous session’s 8% rally. The stock had logged its steepest one-day decline on Monday, as investors locked in profits amid growing worries over AI spending.<\/p>\n
Domestic rival Samsung Electronics dropped more than 7%. Seoul Semiconductor fell more than 5%, LG Innotek lost about 1%, and Samsung SDI was down over 2%.<\/p>\n
The weakness spread across the region. In Japan, AI-linked equipment makers Advantest fell more than 6%, SoftBank Group<\/a> slid nearly 7%, Tokyo Electron<\/a> lost over 5%, while Renesas Electronics<\/a> declined 4%.<\/p>\n The losses track a sell-off in U.S. semiconductor shares overnight. Micron Technology<\/a> sank 8%, Intel<\/a> lost more than 4%, while Lam Research<\/a> and Advanced Micro Devices<\/a> each fell about 3%. <\/p>\n “Today’s decline is largely a follow-on to the US session overnight,” said Rolf Bulk, \u00a0Head of Semiconductor & Infrastructure Equity Research at Futurum Group.<\/p>\n He pointed to a proposed moratorium<\/a> on data-center construction in New York and reports that CoreWeave was exploring hedges against future declines in memory prices as marginally negative signals.<\/p>\n New York Governor Kathy Hochul on Tuesday ordered a temporary halt to new large-scale data center projects while the state develops stricter standards governing their energy, water and environmental impacts.<\/p>\n
