AeroVironment reported earnings last week and dropped nearly 8% on the day — and now, one week later, the stock has shed another 2.2% to $144.17 while shorts have quietly rebuilt positions and another earnings event looms on September 9.
The lending market tells a story of renewed bearish conviction. Availability tightened sharply this week, falling from 65% to 44% — meaning only about one share is now available to borrow for every two already lent out. That's a 20-point move in five sessions. For context, availability briefly plunged to 8-9% in late July and early August, the tightest it had been all year, before the August 14 flush pushed it back above 75%. The current re-tightening is a clear signal that short sellers are re-entering the position after that relief period. Short interest confirmed the move, jumping 4.3% in a single session on September 1 to reach 8.2% of the free float — still below the late-July peak but the direction of travel reversed. Cost to borrow remains low at 0.59%, up about 8% on the week, so the renewed demand for borrows hasn't yet flowed through into a borrow squeeze. The ORTEX short score has climbed to 65.7, its highest reading in two weeks, consistent with a positioning picture that is quietly tightening again ahead of next Tuesday's print.
Options traders are neither alarmed nor complacent. The put/call ratio of 0.70 sits almost exactly in line with its 20-day average of 0.70, with a z-score of just 0.34 — well inside normal territory. The 52-week PCR range runs from 0.44 to 1.08, placing the current reading near the middle. That neutral options posture contrasts with the more directional signal from the lending market: shorts are adding but the derivatives market has not swung defensive. The two data sets are diverging rather than confirming.
The Street is broadly bullish but has grown less aggressive on price targets. The consensus sits at "buy" with six outperform ratings and three holds, and the mean target of $232 implies substantial upside from current levels — though it's worth noting the bulk of analyst activity dates from early-to-mid July, when the stock was trading materially higher. Several firms trimmed targets in that period: Citizens moved from $350 to $230, Canaccord from $280 to $240, Piper Sandler from $248 to $235, and Jefferies from $305 to $229. RBC simultaneously downgraded to Sector Perform. Raymond James ran counter to the group, upgrading to Outperform at a $210 target. The picture is one of bulls holding ratings while marking down expectations — not capitulation, but a Street that has recalibrated the near-term risk. The EPS momentum factor score of 7 on a 90-day basis underlines why: forward estimates have been drifting lower. The short score factor ranks in the 6th percentile, meaning the stock scores as one of the more heavily shorted names in the universe.
The ownership register carries one headline item that has been consistent since May 2025: Altitude V Holdings, an activist filer on Schedule 13D, disclosed a 13.5% stake as of June 2026, down from 14.7% previously. An activist on the register at that scale is a meaningful structural fact — though Schedule 13D/G positions are event-driven disclosures around the 5% threshold, and the actual current stake may differ from the last-filed figure. The passive base is orderly: BlackRock at 6.9% added modestly, Geode and Invesco both built positions last quarter, while Vanguard's separate filing shows a reduction to zero — a notable 13G exit worth monitoring for follow-on disclosure.
Sector peers have also had a rough week. KTOS fell 6.3%, RCAT dropped 9.3%, RDW lost 10.6%, and AIRO shed 10.3%. AVAV's 2.2% weekly decline looks orderly by comparison. The September 8 earnings event — the second in a fortnight given the August 24 print — arrives with the stock down 39% year-to-date, shorts re-loading after their post-earnings relief, and a lending market that has tightened meaningfully in five sessions without the borrow cost yet reflecting that pressure.
What to watch: whether availability continues tightening through the pre-earnings period and whether cost to borrow begins to move in tandem — that combination would signal the lending market is pricing in genuine event risk, rather than simply drifting with positioning flows.
