Nvidia (NVDA) Stock Trades Down, Here Is Why - Yahoo Finance

On June 23, 2026, NVIDIA (NVDA) stock dropped 3.7% in the afternoon session following news that SK Hynix, a major supplier of high-bandwidth memory (HBM), is slowing its HBM4 expansion. While this ini... Read original →

SK Hynix’s HBM4 slowdown stems not from weakening AI demand but from opportunistic shifts toward higher-margin conventional DRAM amid surging spot prices. This tactical pivot tightens near-term supply for NVIDIA’s Blackwell and Vera Rubin platforms, potentially delaying deployments and pushing system designers toward costlier hybrid packaging like CoWoS-L. Geopolitically, U.S.-Korea alignment on memory export controls reduces buffer room for Taiwan, China and Korean suppliers, heightening supply chain fragility. Samsung and Micron may seize the opening, yet both trail SK Hynix by 6–9 months in HBM4 yield maturity. Over the next 12–24 months, persistent HBM bottlenecks will accelerate adoption of chiplet-based architectures and force TSMC and Intel to fast-track advanced packaging capacity. The market’s knee-jerk reaction overlooks the structural reality: AI infrastructure investment continues its exponential climb.
