10. Teradyne Inc. (NASDAQ:TER)

Teradyne extended its winning streak for a fourth consecutive day on Monday, jumping 12.79 percent to close at $135.18 apiece as investors took heart from an analyst’s upgraded price target and bullish rating for its stock.

“Recent checks in Taiwan with key players in the AI compute supply chain indicate [Teradyne Inc. (NASDAQ:TER)] is gaining meaningful traction at TSMC (Taiwan Semiconductor Manufacturing Co.), particularly for GPU wafer sort testing,” Susquehanna said.

“TSMC is expecting to begin acquiring TER’s [system-on-a-chip] testers for this purpose, with additional units to be purchased and consigned to OSA partners in 2026. While we don’t anticipate a material incremental revenue contribution from this win until 2026, TER’s growing presence across multiple test insertion points—wafer sort and potential adoption at System Level Test (SLT)—is a positive and incremental development that we believe is not entirely reflected in the current share price,” it noted.
