SKHX is trading 3.97% up at $9.68 after-hours, but the reason for the move remains unclear.

  • The regular-session close was $9.31; no verified company-specific announcement or clear after-hours catalyst was found.
  • SKHX is a 2× daily leveraged ETF tied to SK Hynix.
  • Reports described a sharp selloff in Korean semiconductor shares on October 20, but that sector context does not explain the opposite-direction after-hours gain.
