🔴 Photonics ETF (EUVL.DE) is trading 5.28% down after profit-taking reversed the AI-driven optical rally

EUVL.DE is trading at €7.30 (-5.28%), most likely reflecting profit-taking after the prior AI-driven rally.

• No company-specific catalyst for August 18, 2026 was identified; the rally followed Anthropic revenue reports and renewed confidence in AI infrastructure spending.
• Optical-networking shares rallied sharply after Lumentum’s results and upbeat demand commentary, leaving the sector vulnerable to near-term consolidation.
• The move appears sector-specific: semiconductor and AI-linked stocks remained supported during August 17 session, while major U.S. indexes were mixed to lower.
