On September 14, Teradyne fell 3.87% in pre-market trading, trading at $359.98/share, with turnover of $503,000, as the broader semiconductor equipment sector came under widespread selling pressure.

On the news front, escalating US-China trade friction coupled with tightened semiconductor export controls exerted systematic pressure across the equipment sector. The entire semiconductor equipment group declined in tandem, with AXT Inc down 6.75%, KLA Corporation down 5.0%, Lam Research down 5.0%, Applied Materials down 5.0%, and ASML Holding down 4.43%. Notably, Applied Materials saw its stock weaken despite reporting third fiscal quarter revenue of $9.12 billion, up 25% year-over-year, and non-GAAP EPS of $3.50, both exceeding expectations — reflecting a broader pattern of elevated valuations meeting macro headwinds.

Teradyne had previously rallied on the back of strong Q2 results — revenue of $1.33 billion, up 104% year-over-year, and net income growth of 373% — along with the launch of three new AI and data center testing instruments on its UltraFLEXplus platform. However, the current sector-wide pullback driven by geopolitical and trade policy concerns has overshadowed these company-specific tailwinds.
