On August 18, Teradyne fell 4.54% in pre-market trading, trading at approximately $426.78/share, with turnover of approximately $1.3 million.

The semiconductor equipment sector where Teradyne belongs came under broad selling pressure. Among individual stocks, Applied Materials fell 3.31%, Lam Research fell 3.21%, ASML Holding fell 3.29%, KLA Corporation fell 2.99%, and AXT Inc fell 6.79%. The sector-wide pullback followed a strong rally in recent sessions, with Teradyne having surged over 5% in the prior trading day amid renewed AI optimism fueled by strong financials from major AI companies and fresh data center investment commitments.

Teradyne previously reported Q2 revenue of $1.33 billion, representing 104% year-over-year growth driven by AI chip testing demand, with Q3 guidance significantly above consensus. After accumulating substantial gains since its earnings beat, the stock appears to be experiencing profit-taking alongside the broader sector rotation.
