Samsung and SK Hynix Lead Mixed Asian Stocks

Asia–Pacific stocks were mixed Friday, with sentiment tethered to Wall Street’s pullback, but South Korea’s chip leaders broke away. 

SK Hynix jumped 8.22% and Samsung Electronics rose over 6%, both to record highs after a near weeklong holiday, as investors priced in fresh artificial-intelligence demand. 

Momentum followed headlines that could see OpenAI take a 10% stake in AMD, sending AMD up more than 40% week to date, while Nvidia gained 2.6% over the same period on signs of stronger recent demand and continued backing of new AI ventures.

Regionally, though, Japan lagged. The Nikkei 225 fell 1.01% to 48,088.8 and the Topix lost 1.85% to 3,197.59. Korea outperformed, with the Kospi up 1.73% to 3,610.6 and the Kosdaqhigher by 0.61% to 859.49 as chipmakers pulled the complex higher. 

The cross-current came from the U.S., where the major averages eased: the S&P 500 slipped 0.28% to 6,735.11, the Nasdaq Composite edged down 0.08% to 23,024.63, and the Dow fell 0.52% (−243.36) to 46,358.42 while the federal government shutdown continued to cloud the macro backdrop.

What Does This Mean for Me?

The takeaway for equity investors remains that AI capex is still the market’s clearest growth lane, supporting high-beta chip names even as broader indices consolidate. With week-to-date gains in U.S. AI bellwethers feeding through to Asia’s memory and logic suppliers, positioning continues to favor semiconductors and adjacent hardware.
