ESRT enters its April 30 Q1 earnings release with a short position that swelled sharply over the past month, even as borrowing costs signal this is still a low-tension trade.
The most striking feature of the setup is the scale of the recent short-interest build. At 7.4% of free float, the short position is not trivially sized — and it grew 25% over the past month, jumping from roughly 9.5 million shares in early April to above 13 million before pulling back modestly this week. That 4-5 percentage-point surge coincides almost exactly with the mid-April tariff-volatility window, when macro uncertainty weighed hard on office REIT sentiment. The ORTEX short score of 60.7 places ESRT in the elevated range, ranking in just the 6th percentile of stocks on short-score rank — meaning shorts are more concentrated here than in 94% of peers. Days to cover of 8.2 underscores that unwinding this position would take time.
Yet the borrow market itself tells a calmer story. Cost to borrow has barely moved, running at 0.56% — essentially the cost of lending overnight cash. Availability has eased back from its most-compressed levels in mid-April, and the stock's recent price action has been recovering: ESRT gained 13% over the past month to close at $5.62, despite pulling back 1.9% on Tuesday. Office-REIT peers were notably stronger on the day — rose 1.9%, gained 1.5%, and added 3.4% — suggesting the Tuesday dip was ESRT-specific rather than sector-wide. Options positioning is broadly neutral; the put/call ratio of 0.036 is barely above its 20-day average, making options traders the least interesting part of the story here.
The analyst community has moved firmly in one direction over recent months. Citigroup cut its target twice since February — most recently to $5.75 on April 15 — while maintaining Neutral, and Wells Fargo has held an Underweight stance with a $6.30 target. The mean consensus target of $6.61 sits modestly above the current price, but the direction of travel has been consistently downward. Bears point to the office sector's structural headwinds and ESRT's heavy reliance on Manhattan occupancy and tourism-driven observatory revenue. On the other side, the stock's 13% recovery from March lows suggests some investors see the selloff as overdone, and Cohen & Steers entered a significant position, adding over 9 million shares through year-end 2025.
The Q1 print will test whether leasing momentum and observatory traffic trends can validate the recovery in the stock price — or confirm why short sellers rebuilt their position so aggressively through April.
