Teradyne Inc. (US8807701029) stock closed at $383.15 on August 20, 2026, after a strong rally that has pushed the shares close to their recent highs and set up a new debate over valuation and future growth.
Downgrade highlights valuation and catalyst debate
A recent analyst call reported by Investing.com on August 21, 2026, pointed to valuation concerns and a lack of near-term catalysts, with the firm moving Teradyne's rating to Neutral from Outperform and setting a price target of $420.00.
At the August 20, 2026 Nasdaq close, separate market data showed Teradyne at $383.15, implying a discount of $36.85, or 8.8 percent, to that $420.00 target and offering a concrete benchmark for investors weighing how much upside remains in the stock.
Consensus targets compiled on August 21, 2026 by MarketScreener sit higher at an average of $449.80, which is $66.65, or 17.4 percent, above the $383.15 last closing price and illustrates that most covering analysts still see meaningful upside even after the downgrade.
Price performance and technical context
Data from a stock chart overview on August 20, 2026 shows Teradyne trading at $379.65 intraday with a market capitalization of $59.35 billion and a volume of 2.76 million shares, underscoring the stock's large-cap profile and active trading environment.
Additional quote information indicates that at the official 4:00 p.m. ET close on August 20, 2026 Teradyne was marked at $383.15, up 0.92 percent on the day, while after-hours trading pushed the quote to $385.00, a further gain of 0.48 percent that suggests continued investor interest beyond regular hours.
Sector and consensus data compiled on August 21, 2026 show the same $383.15 last closing price paired with the $449.80 average target, and also report the stock's year-to-date performance at 97.95 percent, confirming that Teradyne has almost doubled for investors since the start of 2026.
A separate sector chart snapshot on August 21, 2026 translated into euros records Teradyne at EUR 327.75 in real-time pre-market CBOE data, with a five-day change of 0.38 percent and a year-start change of negative 6.63 percent on that venue, highlighting how the strong Nasdaq move contrasts with a softer performance in the European trading environment.
Ownership flows and consensus backdrop
Recent institutional filings summarized on August 21, 2026 show new positions being taken in Teradyne, including an investment valued at $4.04 million that reflects continuing demand for exposure to the company despite valuation concerns.
Other filings the same day point to additional share purchases and note that Teradyne carries a consensus rating characterized as Moderate Buy, with a separate average target cited at $396.80, which stands $13.65, or 3.6 percent, above the $383.15 last close and reinforces that the downgrade has not overturned the broader constructive view.
Moving-average data from an ownership report dated August 21, 2026 indicates Teradyne's fifty day moving average price at $387.01 and its 200-day moving average price at $353.63, signaling that even after the rally the stock still trades only slightly below its short-term trend line but nearly 8.4 percent above its longer-term average.
Those moving averages frame the current consolidation phase, with the $383.15 close sitting 0.99 percent below the fifty day moving average and 8.35 percent above the 200-day mark, a band that many technical traders regard as a zone where momentum can either pause or extend depending on incoming company and sector news.
Product and business context: semiconductor test systems
Teradyne Inc. is globally recognized for its automated test equipment, particularly advanced semiconductor test systems used to validate integrated circuits and system-on-chips before they enter mass production, and this franchise underpins the long-run investment case for the stock.
One representative product line is Teradyne's portfolio of system-on-chip and memory test platforms designed for cutting-edge logic, analog, and mixed-signal devices, which help chip manufacturers improve yields, shorten time-to-market, and manage the complexity of ever more advanced semiconductor designs.
These solutions are deployed across leading fabrication facilities and outsourced semiconductor assembly and test providers, allowing Teradyne to participate in broad industry trends such as demand for AI accelerators, high-performance computing, and 5G infrastructure, even though the stock's short-term moves can be driven by valuation and sentiment swings like the downgrade highlighted earlier.
Teradyne stock and current market level
As of August 20, 2026, 4:00 p.m. ET, Teradyne stock on the Nasdaq closed at $383.15 per share in U.S. dollars, with an after-hours indication at $385.00 and a market capitalization measured at $59.35 billion on same-day chart data.
Placed against the $449.80 average analyst target and the $420.00 specific downgrade target, that closing price leaves Teradyne trading between 8.8 percent and 17.4 percent below these reference points, which captures the current balance between a strong year-to-date rally and lingering questions over how much further the shares can climb without fresh operational catalysts.
