Lumentum is trading 4.2% down at $798.92 as photonics and AI-infrastructure names see choppy action following Alphabet’s sharply higher 2026 capex plans.
- The stock had surged earlier this week alongside other photonics plays, but some of that move is now unwinding in a risk-off tech tape and broader AI-spending reassessment.
- No new company-specific headlines have been identified for Lumentum to account for today's price action.
