🔴 MKS Instruments is trading 9% down today on a sharp semiconductor sector reversal

MKS Instruments is trading 9% down today at $302.82 following a sharp reversal from last week’s semiconductor rebound and pre-market strength.

• The decline is driven by renewed selling across chip and equipment names and profit-taking following a significant year-to-date rally.
• The stock is facing pressure from sector-wide concerns regarding advanced Chinese chipmaking equipment and stretched AI valuations rather than any new company-specific news.
