📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their AMSC 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
238 funds currently hold this stock — 88% of the 3.0-year high of 272 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀
Fast accumulation — +24% more funds vs a year ago
fund count last 6Q
+46 new funds entered over the past year (+24% 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.
🟡
Slight buying edge — 52% buying
152 buying142 selling
Last quarter: 152 funds bought or added vs 142 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
⚠️
Fewer new buyers each quarter (-33 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 39 → 66 → 73 → 40. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒
46% of holders stayed for 2+ years
■ 46% conviction (2yr+)
■ 30% medium
■ 24% new
110 out of 238 hedge funds have held AMSC 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.
💎
Buying through price weakness — shares +1%, value -51%
Last quarter: funds added +1% more shares while total portfolio value only changed -51%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
➡️
Steady discovery — ~40 new funds/quarter
56 → 39 → 66 → 73 → 40 new funds/Q
New funds entering each quarter: 39 → 66 → 73 → 40. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️
Deep conviction — 59% of holders stayed 2+ years
■ 59% veterans
■ 13% 1-2yr
■ 28% new
Of 253 current holders: 149 (59%) 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.
🏆
Elite ownership — 50% AUM from top-100 funds
50% from top-100 AUM funds
47 of 238 holders are among the 100 largest funds by AUM, controlling 50% of total institutional value in AMSC. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 3.5/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
