Smart Money Signals — IDYA

Based on 254 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added IDYA 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
254 hedge funds hold IDYA 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 — +27% more funds vs a year ago

fund count last 6Q
+54 new funds entered over the past year (+27% 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

137 buying112 selling
Last quarter: 137 funds bought or added vs 112 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 (-11 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 32 → 45 → 57 → 46. 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.
🔒

43% of holders stayed for 2+ years

■ 43% conviction (2yr+) ■ 28% medium ■ 29% new
109 out of 254 hedge funds have held IDYA 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.
📈

Growing discovery — still being found

27 → 32 → 45 → 57 → 46 new funds/Q
New funds entering each quarter: 32 → 45 → 57 → 46. A growing number of institutions are discovering IDYA each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 50% veterans vs 33% newcomers

■ 50% veterans ■ 18% 1-2yr ■ 33% new
Entry-cohort mix of 267 holders: 133 (50%) are 2+ year veterans, 47 entered 1–2 years ago, and 87 (33%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 58% AUM from top-100 funds

58% from top-100 AUM funds
53 of 253 holders are among the 100 largest funds by AUM, controlling 58% of total institutional value in IDYA. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.1
out of 10
Moderate Exit Risk
Exit risk score 4.1/10 — 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.
