SK Hynix is trading $139.98 (+6.30%) in pre-market amid a sector-wide memory rally; no clear company-specific catalyst directly explains the rise.

  • The sector move is tied to AI infrastructure demand and upbeat memory-price expectations.
  • SK Hynix shelved a potential U.S. listing of Solidigm, citing market conditions and share-price trends; reports do not connect the decision to the pre-market gain.
