SK hynix Inc. shares fell more than 5% in early trading in South Korea on November 3, 2026. They traded at 1,393,000 won, down 5.37% from the previous session. Foreign and institutional investors reportedly led the selling. [2, 4]
The decline followed a broader technology-stock downturn that began on the New York Stock Exchange. Renewed concerns about the profitability of artificial intelligence investments reportedly unsettled investors after major technology companies announced large-scale spending on AI infrastructure. Semiconductor stocks fell globally. [2]
Merrill Lynch and JPMorgan were among the brokerage firms listed as top sellers of SK hynix shares. [2]
The decline contrasted with recent positive news for the company: record third-quarter earnings and strong long-term demand forecasts for its AI memory chips. Those developments had supported pre-market trading in its U.S.-listed shares. [1, 8]
