Semiconductor equipment and chipmaking shares declined during trading as supply chain disruptions in Taiwan and competitive advancements from Chinese manufacturers weighed on the broader sector. Teradyne, Inc. (NASDAQ:TER) dropped 4.31%, Himax Technologies, Inc. (NASDAQ:HIMX) fell 3.65%, Kulicke & Soffa Industries, Inc. (NASDAQ:KLIC) slid 3.51%, Lattice Semiconductor Corporation (NASDAQ:LSCC) lost 2.74%, and Amkor Technology, Inc. (NASDAQ:AMKR) fell 2.20%.

The market pressure follows escalating labor negotiations in Taiwan, where union workers voted to authorize a potential strike affecting key memory production facilities. At the same time, Chinese memory maker ChangXin Memory Technologies unveiled progress on next-generation DRAM server-memory modules scheduled for late 2026. Higher borrowing costs added to headwinds as 10-year Treasury yields exceeded 5.3% after Federal Reserve meeting minutes noted support for higher interest rates.

Moving forward, investors will watch whether labor disputes in Taiwan result in actual production outages. Markets will also keep an eye on whether new memory technologies can be produced in commercial volumes, as well as upcoming interest rate data from the Federal Reserve.
