Teradyne Inc. (ISIN US8807701029) reached USD 393.42 on Nasdaq during September 22, 2026 trading, up USD 11.88 from the prior close. The move followed a new semiconductor test partnership and came after a 5.2 percent gain to USD 371.47 on September 21, 2026.
Partnership targets AI testing
As TradingView reported on September 22, 2026, GSME and Teradyne announced a multi-year partnership to establish a semiconductor test and evaluation center. The facility is planned for GSME's 42,000 square-foot Silicon Valley headquarters, with operations scheduled to begin in Q4 2026.
The center is designed to support AI, silicon photonics, automotive, power management and RF applications. The commercial significance is practical: Teradyne equipment would be used for customer demonstrations, device evaluations, engineering development, pilot production and technical training.
Quarterly figures support valuation
Teradyne's latest reported quarter was Q2 2026. According to MarketBeat on September 22, 2026, earnings reached USD 2.47 per share against consensus of USD 2.09, a USD 0.38 beat. Revenue was USD 1.33 billion, up 103.9 percent from the same quarter of the previous year and above expectations of USD 1.22 billion.
The comparison matters because the stock is priced for continued execution. MarketBeat cited a market capitalization of USD 61.51 billion, a price-to-earnings ratio of 54.08 and a 52-week range from USD 128.59 to USD 487.91 as of September 22, 2026. The valuation therefore leaves semiconductor demand and AI-related product adoption central to the investment case.
Stock remains below yearly high
Teradyne traded at USD 393.42 on Nasdaq during September 22, 2026, with 772,896 shares exchanged in the cited market snapshot. That level was USD 94.49 below the 52-week high of USD 487.91 and USD 264.83 above the 52-week low of USD 128.59.
Analyst expectations remain mixed in the data cited by MarketBeat on September 22, 2026. Morgan Stanley raised its target from USD 387.00 to USD 397.00 and kept an equal-weight rating, while Evercore maintained an outperform rating with a USD 420.00 target. The same overview reported an average target of USD 396.80 and a moderate-buy consensus.
The immediate counter-factor is valuation sensitivity. With a P/E ratio of 54.08 and a share price below the yearly high, the market is already assigning substantial value to future growth in semiconductor testing, AI infrastructure and robotics.
Nasdaq price holds above USD 390
Teradyne stock stood at USD 393.42 on Nasdaq as of September 22, 2026, up USD 11.88 on the session. The combination of the new partnership, Q2 revenue of USD 1.33 billion and the USD 0.38 EPS beat gives the current price move a measurable operating backdrop.
