SK Hynix sinks after Nasdaq debut amid profit-taking, easing earnings optimism

South Korea's SK Hynix saw its Nasdaq-listed ADRs decline after a strong debut, with profit-taking and easing earnings optimism weighing on sentiment. The stock had opened about 14% above its offer price of $149 before settling with a 12.8% gain on day one; analysts flagged softer-than-expected HBM4 chip shipments and moderated DRAM price benefit versus peers. South Korea's KOSPI was down 2.8% as the listing euphoria faded.
