SK Hynix Leads Asian Tech Rebound After Volatile US Trading Debut

South Korea's SK Hynix led a broad rebound in Asian technology stocks, closing over 8% higher in Seoul after its US-listed shares surged more than 27% overnight. The recovery followed a turbulent stretch for the memory-chip maker, whose roughly $26.5 billion Nasdaq listing, one of the largest American depositary receipt offerings ever, was met with enthusiasm before triggering sharp swings. Earlier in the week the stock suffered its steepest one-day decline in Seoul as investors locked in profits and fretted that the artificial intelligence spending boom had become overextended, dragging down memory peers globally. A downgrade to SK Hynix's second-quarter operating profit outlook by a local brokerage, which pegged profit about 8% below consensus, added to the pressure. The rebound spread across the region, lifting Samsung Electronics, Japan's Advantest, Lasertec and Tokyo Electron, and tracked a recovery in US semiconductor names. Analysts framed the volatility as profit-taking and leveraged-fund positioning rather than a fundamental shift, but the episode highlighted how sensitive markets have become to the AI investment cycle. SK Hynix is due to report earnings on July 22.
