Teradyne, Kulicke and Soffa, Impinj, Microchip Technology, and IPG Photonics Shares Plummet, What You Need To Know

May 15, 2026 - 20:08

A broad selloff hit several semiconductor and chip-equipment stocks during the afternoon trading session on Monday. The decline followed the conclusion of the U.S.-China summit, which ended without any major agreements or concrete progress on semiconductor trade restrictions.

Investors had been watching the high-level talks closely, hoping for signs of easing tensions between the two largest economies. Instead, the lack of a breakthrough left the market disappointed. Shares of Teradyne, a maker of testing equipment for chips, fell sharply. Kulicke and Soffa, which supplies assembly tools for the semiconductor industry, also dropped. Impinj, a company specializing in radio-frequency identification technology, saw its stock decline as well. Microchip Technology, a major producer of microcontrollers and embedded chips, and IPG Photonics, a leader in high-power fiber lasers used in manufacturing, both lost ground.

The broader market also felt the pressure, but the chip sector was hit particularly hard because of its direct exposure to export controls and supply chain uncertainty. Analysts noted that without clear policy signals from either side, companies face continued risk in their China-facing revenue streams. The summit's outcome reinforced the view that trade friction is likely to persist, leaving investors cautious about the near-term outlook for these firms.
