TER heads into July with a striking disconnect: the stock just delivered its best month in years, yet short sellers are piling in at a pace not seen in recent memory.
The rally is real. Teradyne closed June at $483.84, up 15% on the week and nearly 30% over the month. That kind of momentum draws attention from both directions — and the short-side response has been unusually swift. Short interest in TER has nearly doubled over the past month, rising 93% to reach 6.4% of the free float as of June 30. The weekly jump alone was 30%, with shares short climbing from around 7.5 million to just above 10 million in the span of a week. At 2.3 days to cover on the latest FINRA fortnightly data, the position isn't yet unwieldy, but the speed of the buildup is the story.
The borrow market confirms the new demand is active rather than residual. Cost to borrow has risen 67% over the week to 0.63% — still low in absolute terms, but more than double where it sat two weeks ago. Availability remains extremely loose, with roughly 23x more shares available to borrow than are currently shorted, so the lending pool is far from tight. Options traders, meanwhile, are leaning the other way: the put/call ratio has actually drifted below its 20-day average at 0.77, about one standard deviation below the mean. That's a modestly bullish lean from the options market, running counter to the short-side rebuild. Two distinct camps are forming, and they are betting in opposite directions.
The Street has overwhelmingly sided with the bulls this week. Susquehanna lifted its target to $550 on June 30, and Cantor Fitzgerald matched that figure a day earlier, both maintaining positive ratings. B of A Securities raised to $525 the previous week, keeping a Buy. The pattern is consistent: targets are moving up sharply and all recent moves are upgrades or raises, none cuts. The consensus target of around $407 now looks stale relative to the recent flurry — several of the freshest targets are 14%-plus above current levels. The bull case centres on AI-driven semiconductor test revenue already exceeding 50% of the segment mix and a projected path to $5 billion in revenue by 2027, with HDD testing seen doubling by 2026. Bears counter with execution risk in robotics, customer concentration, and the ever-present US-China trade tension clouding demand visibility. The ORTEX short score has been drifting higher this month, reaching 40.9 from 34.7 two weeks ago, reflecting the rising short interest even if the absolute level is still moderate. The P/E has expanded to 51x and EV/EBITDA to 38.6x as price has run ahead of earnings estimates — the 30-day change in the P/E multiple alone is 6.8 points.
Insider activity offers a mild caution. CEO Gregory Smith sold 4,000 shares on June 15 at $423, collecting $1.7 million, following an even larger sale in May of nearly 8,600 shares for $2.9 million. Net insider activity over the past 90 days totals roughly $7.8 million in net selling — not unusual for executives diversifying at elevated prices, but worth noting given the concurrent short-side buildup. Peer performance broadly corroborates the week's move: UCTT gained 28% and AMAT and KLAC each rose around 23%, so TER's 15% week largely tracks the sector, though it led on the month.
The next earnings date is July 29. After the April print, TER fell nearly 10% the following day before recovering to roughly flat by week five — a pattern that emphasises how sharply the stock can react to guidance, particularly around AI test demand and any update on the robotics trajectory. With shorts newly rebuilt at a month-long high and analyst targets freshly reset well above current levels, the July 29 report becomes the focal point where the two camps will finally get resolution.
