Smart Money Signals — AMRN

Based on 71 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds reduced or closed their AMRN 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 39% of 3.0Y high

39% of all-time peak
Only 71 funds hold AMRN today versus a peak of 182 funds at 2023 Q2 — just 39% 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
71 fewer hedge funds hold AMRN 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 — 48% buying

29 buying31 selling
Last quarter: 31 funds reduced or exited vs 29 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 — ~6 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 16 → 11 → 10 → 6. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

75% of holders stayed for 2+ years

75% conviction (2yr+) 18% medium 7% new
53 out of 71 hedge funds have held AMRN 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.
⚠️

Saturation — most institutions already know this story

13 → 16 → 11 → 10 → 6 new funds/Q
New funds entering each quarter: 16 → 11 → 10 → 6. 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.
🏛️

Veteran-anchored — 81% veterans vs 8% newcomers

81% veterans 11% 1-2yr 8% new
Entry-cohort mix of 74 holders: 60 (81%) are 2+ year veterans, 8 entered 1–2 years ago, and 6 (8%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

Strong quality — 22% AUM from major funds

22% from top-100 AUM funds
15 of 71 holders rank in the top 100 by AUM, accounting for 22% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
1.0
out of 10
Low Exit Risk
Exit risk score 1.0/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
