Smart Money Signals — ILMN

Based on 843 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 ILMN 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
843 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.
📶

Steady growth — +19% more funds vs a year ago

fund count last 6Q
+132 new funds entered over the past year (+19% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction. The peak was reached in just 3 quarters from the low — a sharp move.
🟠

More sellers than buyers — 48% buying

397 buying431 selling
Last quarter: 431 funds reduced or exited vs 397 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 (-81 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 127 → 110 → 181 → 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.
🔒

64% of holders stayed for 2+ years

■ 64% conviction (2yr+) ■ 19% medium ■ 17% new
541 out of 843 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.
📈

Growing discovery — still being found

91 → 127 → 110 → 181 → 100 new funds/Q
New funds entering each quarter: 127 → 110 → 181 → 100. A growing number of institutions are discovering ILMN each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 69% veterans vs 21% newcomers

■ 69% veterans ■ 10% 1-2yr ■ 21% new
Entry-cohort mix of 870 holders: 603 (69%) are 2+ year veterans, 87 entered 1–2 years ago, and 180 (21%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 43% AUM from top-100 funds

43% from top-100 AUM funds
65 of 839 holders are among the 100 largest funds by AUM, controlling 43% 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.
3.8
out of 10
Low Exit Risk
Exit risk score 3.8/10 — 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.
