MKS Instruments Inc (MKSI) closed at 365.56 USD for the week ended July 3, down -5.9% after a 21.2% four-week rise. The weekly price path over 52 weeks shows the pullback arriving after a broader advance rather than from a flat base.

Confirmation is mixed. The trend signal remains active, Relative Strength is 61.2, and Market Dynamics at 1.61 still points to positive pressure, while volume readings are not uniformly supportive of the move.
