Smart Money Signals — INSM

Based on 672 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, 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 (99% of max)

99% of all-time peak
672 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
+235 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.
🟡

Slight buying edge — 55% buying

401 buying325 selling
Last quarter: 401 funds bought or added vs 325 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 (-104 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 129 → 129 → 204 → 100. 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.
📌

Mixed — 35% long-term, 38% new

■ 35% conviction (2yr+) ■ 26% medium ■ 38% new
Of the 672 current holders: 236 (35%) held >2 years, 178 held 1–2 years, and 258 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.
📈

Growing discovery — still being found

61 → 129 → 129 → 204 → 100 new funds/Q
New funds entering each quarter: 129 → 129 → 204 → 100. A growing number of institutions are discovering INSM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 42% veterans vs 43% newcomers

■ 42% veterans ■ 15% 1-2yr ■ 43% new
Entry-cohort mix of 703 holders: 297 (42%) are 2+ year veterans, 103 entered 1–2 years ago, and 303 (43%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 49% AUM from top-100 funds

49% from top-100 AUM funds
69 of 666 holders are among the 100 largest funds by AUM, controlling 49% 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.
4.6
out of 10
Moderate Exit Risk
Exit risk score 4.6/10 — 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.
