Teradyne Soars 18.88% on $2.12B Volume, 33rd in Market Activity

Teradyne (TER) surged 18.88% on July 30, 2025, with a trading volume of $2.12 billion, marking a 246.44% increase from the previous day and ranking 33rd in market activity. The rally followed the company’s second-quarter results, where adjusted earnings of $0.57 per share and $651.8 million in revenue exceeded expectations. Semiconductor Test Group revenue of $492 million, surpassing forecasts, highlighted AI-driven demand for System-on-a-Chip (SoC) testing solutions.

CEO Greg Smith emphasized AI as the “strongest growth driver,” noting improved visibility for the remainder of the year despite uncertainties in program timelines. Third-quarter guidance projected adjusted EPS of $0.69–$0.87 and revenue of $710 million–$770 million, reflecting sequential growth from Q2. While the outlook fell short of estimates, it underscored resilience in compute, networking, and memory sectors amid weaker automotive and industrial demand.

The stock’s sharp rebound contrasted with a 13.6% decline from the year’s start, reflecting broader semiconductor sector volatility. A prior 3.4% drop on July 16 had followed ASML’s cautionary remarks about 2026 growth, which heightened concerns over trade tensions and supply chain disruptions. Teradyne’s performance, however, highlighted its position as a bellwether for AI-related capital spending, with shares trading 21.9% below their January 2025 52-week high.

A backtested strategy of purchasing top S&P 500 stocks by daily trading volume and holding for one day yielded a 166.71% return from 2022 to the present, outperforming the benchmark by 137.53%. This approach demonstrated consistency across high-volume equities, including Teradyne, underscoring volume-driven positioning as a viable short-term tactic in volatile markets.
