SEMI is trading 2.12% higher at $39.08, with semiconductor-sector strength offering the clearest available context for the move.
- SK Hynix reported record third-quarter results, citing strong AI-memory demand, while semiconductor shares advanced.
- SEMI closed at $38.27 on October 28; no clear SEMI-specific announcement or after-hours catalyst was found.
- The Nasdaq fell 2.14%, so broad-market performance does not explain the move.
