On August 28, MKS Instruments fell 5.21% in regular trading, trading at $257.54 USD/share, with turnover of $106 million. The semiconductor equipment sector faced broad selling pressure as the Philadelphia Semiconductor Index declined 5.45% in the prior week. Market concerns over the sustainability of overseas AI capital expenditure intensified, compounded by the 30-year US Treasury yield rising to 5.31% — a new high. The convergence of revenue slowdown signals, widening losses, and rising financing costs eroded market confidence, triggering continued pullback across AI chip and semiconductor equipment stocks.

Within the Semiconductor Equipment sector where MKS Instruments belongs, the overall sector declined broadly. Among individual stocks, Applied Materials fell 3.77%, ASML Holding NV fell 1.86%, Lam Research fell 3.83%, KLA Corporation fell 3.96%, and Teradyne fell 4.74%.
