Smart Money Signals — INSM

Based on 647 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 INSM 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
647 hedge funds hold INSM 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 — +54% more funds vs a year ago

fund count last 6Q
+228 new funds entered over the past year (+54% 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.
🟢

More buyers than sellers — 61% buying

429 buying278 selling
Last quarter: 429 funds were net buyers (191 opened a brand new position + 238 added to an existing one). Only 278 were sellers (192 trimmed + 86 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+66 vs last Q)

new funds entering per quarter
Funds opening a new INSM position: 59 → 125 → 125 → 191. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 35% long-term, 42% new

■ 35% conviction (2yr+) ■ 23% medium ■ 42% new
Of the 647 current holders: 226 (35%) held >2 years, 149 held 1–2 years, and 272 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
💰

Value +21% but shares only +0% — price-driven

Value
+21%
Shares
+0%
Last quarter: the total dollar value of institutional holdings rose +21%, but actual share count only changed +0%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
🚀

Acceleration phase — new buyers rushing in

63 → 59 → 125 → 125 → 191 new funds/Q
New funds entering each quarter: 59 → 125 → 125 → 191. 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 — 42% of holders stayed 2+ years

■ 42% veterans ■ 15% 1-2yr ■ 44% new
Of 691 current holders: 288 (42%) 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 — 47% AUM from top-100 funds

47% from top-100 AUM funds
44 of 647 holders are among the 100 largest funds by AUM, controlling 47% of total institutional value in INSM. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.7
out of 10
Moderate Exit Risk
Exit risk score 4.7/10 — 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.
