Smart Money Signals — JAZZ

Based on 569 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added JAZZ 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
569 hedge funds hold JAZZ 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 — +5% more funds vs a year ago

fund count last 6Q
+25 new funds entered over the past year (+5% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 55% buying

315 buying260 selling
Last quarter: 315 funds bought or added vs 260 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 (-42 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 59 → 57 → 134 → 92. 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+) ■ 20% medium ■ 20% new
346 out of 569 hedge funds have held JAZZ 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

105 → 59 → 57 → 134 → 92 new funds/Q
New funds entering each quarter: 59 → 57 → 134 → 92. 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.
🏛️

Deep conviction — 68% of holders stayed 2+ years

■ 68% veterans ■ 9% 1-2yr ■ 23% new
Of 582 current holders: 393 (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 — 45% AUM from top-100 funds

45% from top-100 AUM funds
57 of 569 holders are among the 100 largest funds by AUM, controlling 45% of total institutional value in JAZZ. 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.
