📉
Selling streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds reduced or closed their AMBR 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 — 78% of 3.0Y peak
78% of all-time peak
14 funds currently hold this stock — 78% of the 3.0-year high of 18 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀
Fast accumulation — +27% more funds vs a year ago
fund count last 6Q
+3 new funds entered over the past year (+27% 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.
🔴
Heavy selling pressure — only 33% buying
5 buying10 selling
Last quarter: 10 funds sold vs only 5 buyers. This is widespread institutional distribution — not a few funds rebalancing, but a broad exit. High conviction bearish signal.
➡️
Steady new buyers — ~2 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 8 → 10 → 5 → 2. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒
50% of holders stayed for 2+ years
■ 50% conviction (2yr+)
■ 14% medium
■ 36% new
7 out of 14 hedge funds have held AMBR for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
💰
Price up while funds trimmed (-35% value, -52% shares)
Last quarter: total value of institutional AMBR holdings rose -35% even though funds reduced share count by 52%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
⚠️
Saturation — most institutions already know this story
3 → 8 → 10 → 5 → 2 new funds/Q
New funds entering each quarter: 8 → 10 → 5 → 2. Far fewer institutions are entering now vs. a year ago. When the pool of potential new buyers shrinks this fast, future price support from institutional inflows weakens significantly.
🏛️
Deep conviction — 47% of holders stayed 2+ years
■ 47% veterans
■ 7% 1-2yr
■ 47% new
Of 15 current holders: 7 (47%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
✅
Strong quality — 26% AUM from major funds
26% from top-100 AUM funds
6 of 14 holders rank in the top 100 by AUM, accounting for 26% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 3.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
