New York, Feb 26, 2026, 15:27 EST — Regular session
- Teradyne hit a new high earlier but shares slipped back during the afternoon session.
- Chip-linked stocks dropped, with investors rethinking the AI trade following Nvidia’s results.
- A Teradyne officer disclosed a minor planned share sale in a recent regulatory filing.
Teradyne dropped 3.25% to $331.69 Thursday afternoon, after bouncing between $344.92 at its peak and $328.76 at the session low. Volume landed near 3.7 million shares—right around typical levels, according to data.
Teradyne’s role as a momentum stand-in for semiconductor test equipment has grown more pronounced. The company’s shares can swing sharply whenever sentiment on AI demand changes, since its gear is what checks chips before they leave the factory.
The mood flipped Thursday. Nvidia’s results just didn’t clear the bar, sending U.S. indexes south. The Philadelphia Semiconductor Index slid 3.6%, dragging down tech-heavy benchmarks. “They did not hit the high end of some people’s expectations,” said Joseph Sroka, chief investment officer at NovaPoint in Atlanta.

The picture changed on Wednesday. Teradyne jumped 4.17% to finish at $342.82, notching a fresh 52-week high and pulling ahead of rivals like Keysight Technologies, Fortive and Cohu, according to MarketWatch.
Teradyne officer Mills Regan is looking to unload 788 shares, according to a Form 144 filed Wednesday, pegging the total value near $262,000. The filing cites Nov. 25, 2025, as the pre-set date for the trading plan under SEC Rule 10b5-1. Remember, Form 144 simply signals a proposed sale—it doesn’t confirm any shares have traded yet.
Analysts have scrambled to adjust their targets following the rally. Fintel’s average one-year price target jumped to $308.37, up from $242.09, Nasdaq.com reported late Wednesday.
AI-related demand has fueled the surge. Teradyne, earlier this month, projected first-quarter revenue and profit ahead of Wall Street expectations. “Strong momentum in compute driven by AI,” CEO Greg Smith said, according to Reuters. Reuters
The setup isn’t one-sided. If chipmakers start pulling back on capital expenditures, pause on production ramps, or trim test budgets, orders could take a hit—Teradyne’s stock has hardly behaved like a safe, low-volatility play.
Investors are set to tune in for management’s take on demand and margins, with upcoming appearances such as the Morgan Stanley Technology, Media & Telecom Conference on March 2 listed on Teradyne’s investor calendar.
