Smart Money Signals — INBX

Based on 134 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 INBX 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 (96% of max)

96% of all-time peak
134 hedge funds hold INBX 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 — +43% more funds vs a year ago

fund count last 6Q
+40 new funds entered over the past year (+43% 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

79 buying64 selling
Last quarter: 79 funds bought or added vs 64 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 (-26 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 9 → 25 → 47 → 21. 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.
🔒

51% of holders stayed for 2+ years

■ 51% conviction (2yr+) ■ 22% medium ■ 26% new
69 out of 134 hedge funds have held INBX 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.
🚀

Acceleration phase — new buyers rushing in

12 → 9 → 25 → 47 → 21 new funds/Q
New funds entering each quarter: 9 → 25 → 47 → 21. 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.
🏛️

Veteran-anchored — 64% veterans vs 26% newcomers

■ 64% veterans ■ 10% 1-2yr ■ 26% new
Entry-cohort mix of 144 holders: 92 (64%) are 2+ year veterans, 14 entered 1–2 years ago, and 38 (26%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 29% AUM from major funds

29% from top-100 AUM funds
39 of 131 holders rank in the top 100 by AUM, accounting for 29% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.3
out of 10
Moderate Exit Risk
Exit risk score 4.3/10 — 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.
