Smart Money Signals — ILMN

Based on 933 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added ILMN 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
933 hedge funds hold ILMN 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 — +26% more funds vs a year ago

fund count last 6Q
+190 new funds entered over the past year (+26% 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 — 53% buying

474 buying415 selling
Last quarter: 474 funds bought or added vs 415 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 (+66 vs last Q)

new funds entering per quarter
Funds opening a new ILMN position: 112 → 182 → 101 → 167. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

63% of holders stayed for 2+ years

■ 63% conviction (2yr+) ■ 18% medium ■ 19% new
584 out of 933 hedge funds have held ILMN 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.
💰

Value +45% but shares only +27% — price-driven

Value
+45%
Shares
+26%
Last quarter: the total dollar value of institutional holdings rose +45%, but actual share count only changed +27%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
➡️

Steady discovery — ~167 new funds/quarter

128 → 112 → 182 → 101 → 167 new funds/Q
New funds entering each quarter: 112 → 182 → 101 → 167. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 69% veterans vs 21% newcomers

■ 69% veterans ■ 10% 1-2yr ■ 21% new
Entry-cohort mix of 957 holders: 660 (69%) are 2+ year veterans, 99 entered 1–2 years ago, and 198 (21%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 57% AUM from top-100 funds

57% from top-100 AUM funds
68 of 928 holders are among the 100 largest funds by AUM, controlling 57% of total institutional value in ILMN. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.7
out of 10
Low Exit Risk
Exit risk score 3.7/10 — 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.
