SK Hynix shares fell on October 7. This occurred despite news of a strengthened, multi-generational partnership with AMD for high-bandwidth memory (HBM).
AMD CEO Lisa Su visited South Korea. She met with SK Hynix's chief. Su expressed satisfaction with the company's next-generation HBM4. They discussed a long-term supply plan spanning three to five years.
SK Hynix's Seoul-listed shares declined approximately 2.8%. Its Nasdaq-listed ADRs fell 2.4%. This occurred amid a broader market sell-off.
The entire semiconductor sector experienced a downturn. The SPDR S&P Semiconductor ETF (XSD) fell 2.1%. The Philadelphia Semiconductor Index declined 1.5%. Macroeconomic concerns weighed on investor sentiment. Analysts attributed the drop to general market weakness, not the specifics of the AMD collaboration. The AMD collaboration did not yet include firm new purchase commitments.
