Chip Rout Sends Korea's Kospi Down 5.5% as Samsung, SK Hynix Slide on AI and China Fears
A broad selloff in semiconductor and AI-related stocks intensified, with South Korea's Kospi closing down 5.5% after briefly falling more than 7%. Samsung Electronics and SK Hynix fell about 7% and 10% respectively, while the Philadelphia Semiconductor Index dropped over 7% from its monthly high and Taiwan's Taiex and Japan's Nikkei 225 each fell nearly 2%. The trigger was China's CXMT announcing a chip technology breakthrough, compounded by Broadcom CEO Hock Tan's warning about AI financing constraints and investor anxiety over AI spending returns.

AI Trade Cracks Widen as Memory Chip Stocks Tumble on CXMT Breakthrough
Global AI-related stocks came under heavy selling pressure as concerns over Chinese competition, rising rates, elevated valuations, and massive AI infrastructure costs deepened. South Korea's Kospi plunged 5.5% on Tuesday, with Samsung Electronics and SK Hynix falling about 7% and 10% respectively, while the Philadelphia Semiconductor Index dropped over 7% from its monthly high. The latest trigger was China's CXMT announcing a chip technology breakthrough, weakening the bull case for global memory peers. Broadcom CEO Hock Tan compared some AI-driven investor strategies to gambling and warned of funding constraints. Investors are now scrutinizing whether billions spent on chips and data centers can generate sufficient returns, especially as market veterans like Ray Dalio warn of a bubble. Upcoming earnings from ASML and TSMC, plus U.S. inflation data, are seen as key near-term risks.
Read sourceChip Stocks Tumble on AI Spending Fears and Rising Chinese Competition
Semiconductor stocks fell sharply as investors grew concerned about AI-related spending and rising Chinese competition, according to The New York Times. The selloff spread globally: Yahoo Finance reported South Korea's stock market sank 5%, while NBC News said the Kospi index dropped more than 7% amid a semiconductor share sell-off over AI boom worries. CNBC reported that Micron, SoftBank and ASML slid as the Wall Street chip rout spread. Bloomberg said cracks are growing across the AI trade as memory-chip stocks tumble. The reports collectively point to mounting investor anxiety over the sustainability of AI-driven chip demand and competitive pressures from China.
Read sourceAI Selloff Drags Emerging Market Stocks Lower, Weighs on Asian Tech Currencies
A selloff in AI-related stocks intensified, pushing the MSCI emerging markets equity benchmark down more than 2% to a two-month low and dragging Asian technology-hub currencies lower. South Korea's Kospi fell for a fifth straight day, weighed down by chipmakers SK Hynix and Samsung Electronics, while TSMC also declined. The deterioration in AI sentiment stems from concerns over rising investment financing costs for industry leaders and a report suggesting Chinese competitors could intensify competition. Julius Baer CIO Yves Bonzon said that while an earnings boom may justify some AI valuations, uncertain future technology prospects could keep driving volatility and sharp profit-taking. Seoul's decline was exacerbated by reports that China's ChangXin Memory made progress on a new memory architecture also being developed by Korean chip giants. Allspring portfolio manager Gary Tan noted ChangXin fell as much as 5.3% Tuesday, reflecting broader tech hardware selling, though he said advanced AI memory requires lengthy certification cycles so competitive impact may be gradual. The equity slump also pushed the Korean won and Taiwan dollar lower, with the MSCI emerging markets currency index down 0.2%. The Indian rupee outperformed, extending weekly gains to 1.5% after the central bank widened restrictions on certain derivative trades to support the currency. Romanian government bonds weakened versus regional peers as accelerating inflation data could delay rate-cut considerations, with the 10-year yield rising 4 basis points to 7.24%.

Chip Stock Rout Sends Korea's Kospi Down 7% on AI and China Fears
A global selloff in semiconductor stocks intensified, with South Korea's chip-heavy benchmark index briefly falling more than 7% amid mounting concerns over AI overheating and Chinese competition. Samsung Electronics and SK Hynix dropped about 7% and 10% respectively on Tuesday, dragging the Kospi to a 5.5% close. Taiwan's weighted index and Japan's Nikkei 225 each fell nearly 2% after U.S. chipmakers plunged overnight. Investor anxiety over the AI trade deepened after Broadcom's CEO compared market sentiment to a casino and warned that financing would become a key issue. Korea's decline was the steepest, also driven by reports that rival ChangXin Memory Technologies is advancing on a new memory architecture. The Seoul exchange briefly halted program trading on the Kospi for the first time since August. The index is now down a third from its June record high and below its 200-day moving average. Foreign investors accelerated their exit, selling $3.4 billion in Kospi shares on Tuesday, the most since June. ChangXin plans to launch new server memory products by the end of 2026 to achieve higher storage density, renewing fears over Chinese chipmakers' rapid progress. Samsung's record earnings last week failed to lift its stock. Broader worries about the AI boom's durability continue to weigh on the sector after Nvidia-backed data center company Firmus Grid's failed offering last week. Broadcom CEO Hock Tan said financing could be a bigger problem than chip shortages. Upcoming earnings from ASML and TSMC this week will help investors gauge how long profit growth can last. TSMC shares fell 2% on Tuesday.
