SK Hynix shares cost 35% more on US markets than in Korea

As of July 15, 2026, SK Hynix shares traded about 35% higher in the US than in South Korea, per Yahoo Finance. The reason: American buyers want more shares than are available, not any change in the company's value. This follows an 800% rally and a rocky Nasdaq debut July 10. MarketWatch says the swings show "no sign of abating."
