PSTL enters the final week of August with an unusual tension: short sellers have nearly doubled their position in a month, yet the stock just posted its best weekly gain since spring.
The short interest story here is the standout. Bears have added aggressively — SI climbed from roughly 1.7% of free float in late July to 9.1% today, a 415% increase over the past month, with a 43% jump in the last week alone. That kind of acceleration is rare for a small-cap net-lease REIT. Cost to borrow has followed, rising from around 0.12% in early August to 1.65% — still cheap in absolute terms, but the pace of the move is striking: up 235% over 30 days. Borrow availability has tightened considerably too. At 161%, availability has more than halved from above 280% just two weeks ago, meaning the lending pool is being drawn down quickly even if it hasn't reached genuinely stressed levels. The ORTEX short score has jumped from 50.5 to 66.5 in barely two weeks — a signal that the aggregate positioning picture has shifted materially.
Options, however, tell a far calmer story. The put/call ratio is running at just 0.20 — well below its 20-day mean of 0.17 and nowhere near its 52-week high of 0.91 hit in mid-July. That's not the signature of a market bracing for downside. Options traders are effectively sitting out the short-side thesis, leaving the two positioning signals pointing in opposite directions.
The Street has stayed constructive. JP Morgan raised its target to $25 from $23 this morning while holding a Neutral rating — a cautious affirmation that PSTL has earned some credit for the stock's 13% gain since March. Truist and BMO both carry Buy ratings with targets in the $23–$25 range. The consensus mean target is $26.50, roughly 13% above the current $23.40 close. Valuation multiples add nuance: the P/E has compressed nearly 6 points over 30 days to 36x, while EV/EBITDA has eased to 13.9x. The bull case rests on same-store NOI growth projected at 7–9% — a notable step up from 5.5% in 2023 — and PSTL's position as the only public REIT focused entirely on USPS-leased properties. The bear case centres on lease concentration risk: 40% of annual base rent expires by end-2027, which creates meaningful re-leasing uncertainty even with a government tenant.
Two institutional holders are worth noting. FMR added 493,000 shares in the latest filing period to reach 10.2% ownership, while BlackRock added 705,000 shares to reach 9.75%. Both are building positions against a backdrop of rising short interest — a contrast that could reflect different views on the REIT's lease rollover risk, or simply passive-versus-active dynamics at different time horizons.
Next earnings arrive October 30. The two most recent prints produced muted one-day moves of under 1.5% in either direction, suggesting the stock has not historically been a big earnings mover. What to watch between now and then is whether the short interest build continues at this pace — if bears push toward the 52-week utilization high that implies availability dropping toward the 17% floor seen historically, the borrow dynamics become a story in their own right.
