Asian Chip Stocks Drop As SK Hynix Earnings Disappoint
South Korean stocks plunged for a second consecutive day on July 29, 2026, led by memory chipmaker SK Hynix, whose record AI-fueled quarterly earnings of KRW 60.5 trillion fell short of market expectations of KRW 64 trillion. The KOSPI index dropped nearly 13% intraday, triggering a trading halt, before closing 6% down, with a cumulative two-day decline of over 15%. SK Hynix shares tumbled 19% before closing down 9.6%, while Samsung Electronics fell 5.2%. The sell-off spread to other Asian chipmakers including Japan's Kioxia (-13.85%) and Taiwan's MediaTek (-5%). The downturn was exacerbated by concerns over Chinese chipmaking advancements, particularly memory chipmaker CXMT, which surged 12.6% on Wednesday after a 466% gain on its market debut. CXMT, reportedly being courted by Apple as an alternative RAM supplier, threatens the near-90% global RAM market share held by Samsung, SK Hynix, and Micron. China also reportedly made strides in advanced chipmaking machines, pressuring ASML and TSMC. US stock futures remained flat, with Micron slightly below $820 after an 8.8% drop on Tuesday.
SK Hynix's Record Profit Misses Forecasts, Shares Slump 10% Despite Robust AI Chip Demand
SK Hynix reported a record quarterly operating profit that soared more than sixfold, but fell short of lofty investor expectations, causing its shares to slump 9.6%. The earnings miss heightened concerns about a potential slowdown in AI infrastructure spending by big tech firms. Despite the selloff, the company emphasized that demand for AI memory chips remains strong and is pursuing long-term supply agreements (typically five years) with financial safeguards to manage price volatility. SK Hynix plans to raise capital spending to the high-40 trillion won range in 2026, up from 30.2 trillion won in 2025. The company's net cash reached 88 trillion won, approaching its long-term target, but it failed to provide detailed plans for shareholder returns, further dampening investor sentiment. The stock has lost more than half its value since a record high last month but remains up about 115% year-to-date.
AI Memory Boom Goes Bust: Micron, SK Hynix, Sandisk Plunge 30% and Are Still Falling
The article reports a sharp downturn in AI memory stocks, with major players like Micron, SK Hynix, and Sandisk experiencing declines of 30-50% from their peaks. This follows a period of extraordinary gains driven by high-bandwidth memory (HBM) shortages and premium pricing.
