SMHX is trading 1.96% up at $56.48 after semiconductor sentiment improved following SK Hynix’s announced $29 billion share buyback.

  • The fabless semiconductor ETF had fallen 2.12% during the August 19 regular session amid renewed chip selling, elevated Treasury yields, and concerns about stretched AI valuations.
  • The after-hours rebound appears sector-driven rather than company-specific, with no SMHX-specific announcement identified.
