Smart Money Signals — INSP

Based on 296 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 INSP positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊

High ownership — 77% of 3.0Y peak

77% of all-time peak
296 funds currently hold this stock — 77% of the 3.0-year high of 386 funds (reached 2023 Q2). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉

Outflows — 18% fewer funds vs a year ago

fund count last 6Q
65 fewer hedge funds hold INSP compared to a year ago (-18% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠

More sellers than buyers — 47% buying

176 buying202 selling
Last quarter: 202 funds reduced or exited vs 176 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.
⚠️

Fewer new buyers each quarter (-40 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 53 → 63 → 95 → 55. 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.
🔒

61% of holders stayed for 2+ years

■ 61% conviction (2yr+) ■ 17% medium ■ 22% new
180 out of 296 hedge funds have held INSP 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 -2%, value -45%

Value
-44%
Shares
-1%
Last quarter: funds added -2% more shares while total portfolio value only changed -45%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

Growing discovery — still being found

55 → 53 → 63 → 95 → 55 new funds/Q
New funds entering each quarter: 53 → 63 → 95 → 55. A growing number of institutions are discovering INSP each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 68% of holders stayed 2+ years

■ 68% veterans ■ 11% 1-2yr ■ 21% new
Of 306 current holders: 207 (68%) 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 — 40% AUM from top-100 funds

40% from top-100 AUM funds
52 of 296 holders are among the 100 largest funds by AUM, controlling 40% of total institutional value in INSP. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
2.5
out of 10
Low Exit Risk
Exit risk score 2.5/10 — 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.
