How much a stock's price changes over time is important for most investors, since price performance can both impact your investment portfolio and help you compare investment results across sectors and industries.

Another factor that can influence investors is FOMO, or the fear of missing out, especially with tech giants and popular consumer-facing stocks.

What if you'd invested in Teradyne (TER) ten years ago? It may not have been easy to hold on to TER for all that time, but if you did, how much would your investment be worth today?

Teradyne's Business In-Depth

With that in mind, let's take a look at Teradyne's main business drivers.

Headquartered in North Reading, MA, Teradyne designs, develops, manufactures, and sells automated test equipment and robotics products. Its automatic test systems are used to test semiconductors, wireless products, data storage and complex electronics systems in consumer electronics, wireless, automotive, industrial, computing, communications, and aerospace and defense industries.

Robotics products include collaborative robotic arms and autonomous mobile robots (“AMRs”) that are used by global manufacturing, logistics and industrial customers.

Teradyne's semiconductor test products are used both for wafer level and device package testing of semiconductor devices. Its product portfolio comprises the FLEX Test platform, J750 test system, Magnum test platform and ETS platform, each tailored for specific semiconductor testing needs. 

The company’s system Test segment is comprised of three business units: Storage Test, Defense/Aerospace and Production Board Test. Wireless Test business operates under the LitePoint brand name and provides test solutions utilized in the development and manufacturing of wireless devices and modules.

The Robotics segment comprises two business units: Universal Robots and Mobile Industrial Robots (MiR).

Universal Robots offers a variety of collaborative robot models, including the UR15, UR18, UR20 and UR30 in the UR Series, plus UR3e, UR7e, UR12e and UR16e in the e-Series, each with different weight carrying capacity and arm reach. MiR offers four collaborative autonomous mobile robot models, MiR250, MiR600, MiR1350 and the MiR1200 Pallet Jack among its robot products, each with a different payload carrying capacity.

Teradyne had three current reportable segments: Semiconductor Test, Product Test and Robotics. Product Test was created effective March 2025 and includes circuit-board test, wireless test, PIC test, and defense/aerospace test systems. In 2025, the company reported revenues of $3.19 billion.

Teradyne competes globally with key rivals like Advantest, Cohu, Keysight, Test Research, SPEA, Rohde & Schwarz, Anritsu, KUKA, ABB, FANUC, Yaskawa, Techman, Doosan, AUBO, Omron, Fetch, OTTO Motors, Vecna, Seegrid and Balyo.

Bottom Line

Anyone can invest, but building a successful investment portfolio takes a combination of a few things: research, patience, and a little bit of risk. So, if you had invested in Teradyne a decade ago, you're probably feeling pretty good about your investment today.

According to our calculations, a $1000 investment made in August 2016 would be worth $18,029.75, or a gain of 1,702.98%, as of August 24, 2026, and this return excludes dividends but includes price increases.

In comparison, the S&P 500's gained 251.49% and the price of gold went up 231.37% over the same time frame.

Analysts are anticipating more upside for TER.

Teradyne is entering a multiyear growth phase as AI investment expands test needs across compute, memory, networking, storage, power and data center systems. Record first-half results and a firmer second-half outlook show demand broadening beyond hyperscaler compute into memory, Product Test and Robotics. For the third quarter of 2026, Teradyne expects revenues in the range of $1.20-$1.30 billion. Rising wafer capacity, transistor growth, and advanced packaging should lift ATE demand, while merchant GPU shipments and a second hyperscaler qualification have been major growth drivers. Omnyx, Photon 100 and MultiLane extend the portfolio from wafers to racks. However, TER suffers from customer concentration, program timing, muted mobile demand, memory-driven margin dilution, higher operating spending and currency exposure.

The stock is up 7.38% over the past four weeks, and no earnings estimate has gone lower in the past two months, compared to 7 higher, for fiscal 2026. The consensus estimate has moved up as well.

Beyond Nvidia: AI's Second Wave Is Here

The AI revolution has already minted millionaires. But the stocks everyone knows about aren't likely to keep delivering the biggest profits. AI’s second wave is moving from infrastructure to implementation and these companies are at the forefront of this transition, positioned to become what Amazon and Google were to the internet era.
