MACOM is trading 15.4% down at $261.13 in pre-market action, pulling back from recent all-time highs despite strong Q2 2026 results and AI-related optimism.
- The decline follows a period of significant outperformance, with shares retreating as investors lock in gains after an extended AI-fueled rally.
- The move is exacerbated by a broader sell-off across the semiconductor sector affecting richly valued chip stocks.
