Asian Tech Stocks Plunge Amid Chinese Chip Competition and Wall Street Losses
Asian tech stocks plunged sharply following Wall Street losses and renewed competition from Chinese chipmaker CXMT. SK Hynix fell 9% and Samsung lost 8%, while South Korea triggered a trading sidecar as markets awaited key US bank earnings.
Asian technology stocks plunged sharply, led by a severe downturn in South Korea and Japan, as anxieties over artificial intelligence financing and intensifying competition from Chinese chipmakers rattled global markets.
Asian Markets Hit Hard by Semiconductor Sell-Off
South Korea's benchmark Kospi index plummeted more than 6%, falling below the 6,000-point threshold to its lowest level since July 31, while the small-cap Kosdaq index dropped 4.23%. The steep decline prompted the Korea Exchange to activate a sell-side sidecar mechanism, temporarily halting trading for five minutes after Kospi 200 futures dropped by 5% or more.
In Seoul, memory giant SK Hynix saw its shares plunge by 9%, and rival Samsung Electronics lost 8%. Meanwhile, in Tokyo, tech investment titan SoftBank Group dropped 8%, leading a broader retreat among Japanese semiconductor and electronics equities.
Tokyo Electron fell 6.6%, Advantest declined 5.38%, Lasertec dropped 4.76%, Disco lost 4.83%, and Renesas Electronics weakened by 5.89%. The Asian sell-off followed a weak trading session on Wall Street, where the Nasdaq Composite dipped 0.44%, weighed down by concerns over rising competition from Chinese memory manufacturer ChangXin Memory Technologies (CXMT).
Rising Competition and Earnings Focus
CXMT recently reported significant progress in developing a new chip architecture designed to increase memory density by storing more data in a smaller footprint. This development stoked investor worries about potential oversupply and competitive pressure on established players like Micron Technology, which dropped 3.9% in New York.
"Investors are edgy and looking for excuses to take profits in AI-related stocks that have delivered outsized returns this year — particularly in memory stocks," said Wai-Serng Ling, senior equity investment adviser at UBP.
Amid the tech turbulence, Wall Street is also bracing for the start of the third-quarter earnings season. Major US banks including JPMorgan, Goldman Sachs, Citigroup, and Wells Fargo are scheduled to release their quarterly results, alongside health insurance giant UnitedHealth. According to FactSet, analysts expect S&P 500 company earnings to have grown by roughly 30% year-over-year.
