Smart Money Signals — ALNY

Based on 804 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 10 quarters in a row

last 6Q
For 10 consecutive quarters, more hedge funds added ALNY than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
🏔️

At the ownership peak (100% of max)

100% of all-time peak
804 hedge funds hold ALNY right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀

Fast accumulation — +43% more funds vs a year ago

fund count last 6Q
+243 new funds entered over the past year (+43% 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 — 51% buying

441 buying421 selling
Last quarter: 441 funds bought or added vs 421 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 (-52 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 106 → 94 → 213 → 161. 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.
🔒

49% of holders stayed for 2+ years

49% conviction (2yr+) 22% medium 29% new
395 out of 804 hedge funds have held ALNY 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 -3%, value -25%

Value
-25%
Shares
-2%
Last quarter: funds added -3% more shares while total portfolio value only changed -25%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
🚀

Acceleration phase — new buyers rushing in

85 → 106 → 94 → 213 → 161 new funds/Q
New funds entering each quarter: 106 → 94 → 213 → 161. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🏛️

Deep conviction — 58% of holders stayed 2+ years

58% veterans 10% 1-2yr 32% new
Of 843 current holders: 485 (58%) 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 — 69% AUM from top-100 funds

69% from top-100 AUM funds
50 of 804 holders are among the 100 largest funds by AUM, controlling 69% of total institutional value in ALNY. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.4
out of 10
Moderate Exit Risk
Exit risk score 4.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
