📈
Buying streak — 8 quarters in a row
For 8 consecutive quarters, more hedge funds added BBIO 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
460 hedge funds hold BBIO 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 — +50% more funds vs a year ago
fund count last 6Q
+153 new funds entered over the past year (+50% 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 — 56% buying
274 buying212 selling
Last quarter: 274 funds bought or added vs 212 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 (-15 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 87 → 73 → 104 → 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.

Moderate Exit Risk
Exit risk score 4.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
