SK Hynix fell 10% after its $26.5B Nasdaq debut, despite strong Q1 results, due to profit-taking and HBM4 shipment concerns. Western Digital dropped 6%, joining a broader semiconductor selloff triggered by declines in South Korea. The weakness spread to major chipmakers like Micron, Nvidia, and AMD as investors reduced exposure to AI and memory stocks amid geopolitical risks.
