Marvell Technology Group is trading 6.1% down at $185.90 as semiconductor and AI-infrastructure stocks face a sharp pullback following an extended rally.
- The decline aligns with broader weakness in the chip sector, where the SOXX ETF has fallen 3.5% in response to competitive concerns stemming from a reported China tech breakthrough.
- Investors are engaging in profit-taking following the company's meteoric AI-driven gains and its inclusion in the S&P 500 earlier in 2026.
