Smart Money Signals — INSM

Based on 663 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds reduced or closed their INSM positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️

At the ownership peak (98% of max)

98% of all-time peak
663 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 — +29% more funds vs a year ago

fund count last 6Q
+151 new funds entered over the past year (+29% 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 — 50% buying

367 buying368 selling
Last quarter: 367 funds bought or added vs 368 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.
📈

More new buyers each quarter (+14 vs last Q)

new funds entering per quarter
Funds opening a new INSM position: 129 → 204 → 100 → 114. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

42% of holders stayed for 2+ years

42% conviction (2yr+) 30% medium 28% new
279 out of 663 hedge funds have held INSM 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 +34%, value -23%

Value
-22%
Shares
+33%
Last quarter: funds added +34% more shares while total portfolio value only changed -23%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊

Peak discovery — momentum slowing

130 → 129 → 204 → 100 → 114 new funds/Q
New funds entering each quarter: 129 → 204 → 100 → 114. INSM is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Veteran-anchored — 46% veterans vs 37% newcomers

46% veterans 17% 1-2yr 37% new
Entry-cohort mix of 710 holders: 325 (46%) are 2+ year veterans, 123 entered 1–2 years ago, and 262 (37%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 53% AUM from top-100 funds

53% from top-100 AUM funds
67 of 660 holders are among the 100 largest funds by AUM, controlling 53% 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.
3.9
out of 10
Low Exit Risk
Exit risk score 3.9/10 — 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.
