📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their BTAI 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 — 88% of 3.0Y peak
88% of all-time peak
37 funds currently hold this stock — 88% of the 3.0-year high of 42 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀
Fast accumulation — +23% more funds vs a year ago
fund count last 6Q
+7 new funds entered over the past year (+23% 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 — 46% buying
17 buying20 selling
Last quarter: 20 funds reduced or exited vs 17 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 — ~7 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 9 → 12 → 11 → 7. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄
Mostly new holders — 43% entered in last year
■ 3% conviction (2yr+)
■ 54% medium
■ 43% new
Only 1 funds (3%) 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 +54%, value +28%
Last quarter: funds added +54% more shares while total portfolio value only changed +28%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
➡️
Steady discovery — ~7 new funds/quarter
29 → 9 → 12 → 11 → 7 new funds/Q
New funds entering each quarter: 9 → 12 → 11 → 7. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🌱
Early stage — 95% of holders entered in last year
■ 5% veterans
■ 0% 1-2yr
■ 95% new
Of 37 current holders: 35 (95%) entered in the past year, only 2 (5%) 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.
🏆
Elite ownership — 47% AUM from top-100 funds
47% from top-100 AUM funds
11 of 37 holders are among the 100 largest funds by AUM, controlling 47% of total institutional value in BTAI. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

Moderate Exit Risk
Exit risk score 4.1/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
