Smart Money Signals — BMRN

Based on 553 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added BMRN 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 (96% of max)

96% of all-time peak
553 hedge funds hold BMRN 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.
📉

Outflows — 4% fewer funds vs a year ago

fund count last 6Q
26 fewer hedge funds hold BMRN compared to a year ago (-4% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡

Slight buying edge — 56% buying

306 buying244 selling
Last quarter: 306 funds bought or added vs 244 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 (-16 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 87 → 76 → 105 → 89. 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.
🔒

56% of holders stayed for 2+ years

■ 56% conviction (2yr+) ■ 24% medium ■ 20% new
310 out of 553 hedge funds have held BMRN 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

106 → 87 → 76 → 105 → 89 new funds/Q
New funds entering each quarter: 87 → 76 → 105 → 89. A growing number of institutions are discovering BMRN each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 63% veterans vs 25% newcomers

■ 63% veterans ■ 12% 1-2yr ■ 25% new
Entry-cohort mix of 575 holders: 362 (63%) are 2+ year veterans, 70 entered 1–2 years ago, and 143 (25%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 49% AUM from top-100 funds

49% from top-100 AUM funds
61 of 550 holders are among the 100 largest funds by AUM, controlling 49% of total institutional value in BMRN. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.3
out of 10
Low Exit Risk
Exit risk score 3.3/10 — 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.
