SK Hynix shares jump in marquee US debut as AI euphoria persists

SK Hynix debuted on Nasdaq with ADRs opening at $170 against a $149 offer price, in the second-largest US share sale after SpaceX's record IPO last month. The Korean chipmaker, the world's largest producer of high-bandwidth memory (HBM) chips critical for AI GPUs, saw the offering more than seven times oversubscribed. Despite recent pullback, the stock remains around 630% higher over the past year, underscoring continued investor enthusiasm for AI-linked semiconductor stocks.
