On September 4, Teradyne rose 3.38% in pre-market trading, trading at $349.9/share, with turnover of $1.1117 million.

On the news front, Broadcom reported after-hours earnings showing AI semiconductor revenue of $16.7 billion, surging 221% year-over-year, with the CEO raising full-year AI revenue guidance to $58 billion. The stronger-than-expected AI demand data lifted sentiment across the semiconductor equipment sector broadly. Meanwhile, Teradyne recently announced three new test instruments for its UltraFLEXplus platform — the UltraPin5000-EM, UltraPort-PCIe6, and UltraVS64-HP — specifically designed for AI and data center computing devices, signaling the company's continued commitment to expanding its AI testing capabilities.

Teradyne had declined over consecutive sessions after multiple analyst downgrades, including Baird cutting the stock to neutral from outperform with a $420 price target, citing fully priced-in AI testing demand expectations. The current rebound appears driven by the combination of sector-wide momentum from Broadcom's results and a technical recovery from the prior pullback.
