📉
Selling streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds reduced or closed their ACOG 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 — 89% of 3.0Y peak
89% of all-time peak
25 funds currently hold this stock — 89% of the 3.0-year high of 28 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📶
Steady growth — +14% more funds vs a year ago
fund count last 6Q
+3 new funds entered over the past year (+14% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠
More sellers than buyers — 44% buying
8 buying10 selling
Last quarter: 10 funds reduced or exited vs 8 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 — ~3 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 9 → 7 → 7 → 3. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄
Mostly new holders — 32% entered in last year
■ 4% conviction (2yr+)
■ 64% medium
■ 32% new
Only 1 funds (4%) 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 +6%, value -10%
Last quarter: funds added +6% more shares while total portfolio value only changed -10%. 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
2 → 9 → 7 → 7 → 3 new funds/Q
New funds entering each quarter: 9 → 7 → 7 → 3. ACOG is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
📊
Mixed cohorts — 4% veterans, 44% new entrants
■ 4% veterans
■ 52% 1-2yr
■ 44% new
Of 25 current holders: 1 (4%) held 2+ years, 13 held 1–2 years, 11 (44%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
📋
Smaller funds dominant — 1% AUM from top-100
1% from top-100 AUM funds
5 of 25 holders rank in the top 100 by AUM, but together hold only 1% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
Exit risk score 3.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
