📉
Selling streak — 3 quarters in a row
For 3 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.
🔻
Below peak — only 44% of 3.0Y high
44% of all-time peak
Only 8 funds hold AMBR today versus a peak of 18 funds at 2025 Q3 — just 44% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉
Outflows — 50% fewer funds vs a year ago
fund count last 6Q
8 fewer hedge funds hold AMBR compared to a year ago (-50% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠
More sellers than buyers — 46% buying
6 buying7 selling
Last quarter: 7 funds reduced or exited vs 6 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.

💎
Buying through price weakness — shares +13429%, value +8454%
Last quarter: funds added +13429% more shares while total portfolio value only changed +8454%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
⚠️
Saturation — most institutions already know this story
8 → 10 → 5 → 2 → 1 new funds/Q
New funds entering each quarter: 10 → 5 → 2 → 1. 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.
