📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their PSTV positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊
High ownership — 81% of 3.0Y peak
81% of all-time peak
21 funds currently hold this stock — 81% of the 3.0-year high of 26 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀
Fast accumulation — +31% more funds vs a year ago
fund count last 6Q
+5 new funds entered over the past year (+31% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟠
More sellers than buyers — 43% buying
10 buying13 selling
Last quarter: 13 funds reduced or exited vs 10 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
➡️
Steady new buyers — ~6 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 8 → 13 → 11 → 6. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄
Mostly new holders — 62% entered in last year
■ 10% conviction (2yr+)
■ 29% medium
■ 62% new
Only 2 funds (10%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💎
Buying through price weakness — shares -21%, value -75%
Last quarter: funds added -21% more shares while total portfolio value only changed -75%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊
Peak discovery — momentum slowing
7 → 8 → 13 → 11 → 6 new funds/Q
New funds entering each quarter: 8 → 13 → 11 → 6. PSTV is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱
Early stage — 57% of holders entered in last year
■ 29% veterans
■ 14% 1-2yr
■ 57% new
Of 21 current holders: 12 (57%) entered in the past year, only 6 (29%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
✅
Strong quality — 36% AUM from major funds
36% from top-100 AUM funds
7 of 21 holders rank in the top 100 by AUM, accounting for 36% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.

Moderate Exit Risk
Exit risk score 4.5/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
