AI Investment Uncertainty Weighs on Global Chip Sector

SK Hynix shares plunged 15% in Asian markets, signaling renewed volatility in the AI-driven chip sector even after its record $26.5 billion IPO. The downturn dragged peers including Samsung Electronics, Micron, Sandisk, and Western Digital down more than 5%, while Intel, AMD, Broadcom, and Arm Holdings slipped roughly 2% amid broader sector weakness.

■Concerns over SK Hynix's Q3 operating profit trailing consensus estimates fueled profit-taking among investors.

■Recent peaks in the chip sector, driven by AI infrastructure demand, now face scrutiny as hyperscalers may need to raise debt levels to sustain spending.

■A potential slowdown in AI investments could spark further sell-offs in memory stocks critical for AI inference workloads.

Markets are testing the limits of AI-driven demand sustainability. Memory chips, once the darling of tech earnings growth, now face a liquidity crunch amid rising skepticism. Supply chain giants like TSMC and ASML remain exposed to these swings as geopolitical tensions over rare earth elements continue to cloud long-term visibility.
