On September 25, Teradyne rose 3.03% in regular trading, trading at $399.38/share, with turnover of $325 million. The rebound followed two consecutive sessions of cumulative losses exceeding 6%, driven by a combination of company-specific catalysts and broader sector recovery.

On the news front, Teradyne entered a multi-year partnership with GS Microelectronics to co-develop a semiconductor testing center aimed at accelerating engineering support for clients building devices across AI, automotive, and other high-growth verticals. Additionally, the company recently introduced Iris 100, an optical test platform designed for high-volume MicroLED manufacturing. The platform measures individual emitters across microLED arrays — including spectral response, brightness, and uniformity — and integrates with Teradyne's UltraFLEXplus system for combined optical and electrical testing, with a roadmap to add photodetector testing capabilities.

Within the Semiconductor Equipment sector, stocks broadly rebounded. Among individual names, AXT Inc rose 4.21%, Applied Materials rose 2.41%, Lam Research rose 2.35%, ASML Holding rose 1.31%, and KLA Corporation rose 0.5%.
