SK Hynix Jumps 5%, AMD Rises 4% as Korea Becomes the New Catalyst for Global Chip Stocks

AMD rose alongside a broad rebound in global chip stocks after South Korea’s SK Hynix surged and the KOSPI regained attention as a leading signal for AI/semiconductor sentiment. The article says AMD gained about 3% to $514 in early trading, while Intel and NVIDIA also advanced. The move appears more like a technical bounce after a recent AI-chip selloff than a new fundamental catalyst. Still, AMD remains supported by strong AI/data center momentum: Q1 2026 revenue rose 38% YoY to $10.25 billion, data center revenue jumped 57% to $5.78 billion, and management guided Q2 revenue to $11.2 billion, implying 46% YoY growth. The bull case is continued AI demand and the MI450 ramp, but valuation risk is highlighted after a 209% run over the past year. Korea’s market moves and semiconductor sentiment are now acting as a cross-border driver for U.S. chip stocks.
