📈
Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added JBIO 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
118 hedge funds hold JBIO 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 — +11700% more funds vs a year ago
fund count last 6Q
+117 new funds entered over the past year (+11700% 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 — 58% buying
65 buying48 selling
Last quarter: 65 funds bought or added vs 48 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 (-9 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 68 → 9 → 36 → 27. 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.
🔄
Mostly new holders — 51% entered in last year
■ 3% conviction (2yr+)
■ 46% medium
■ 51% new
Only 4 funds (3%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
📊
Peak discovery — momentum slowing
0 → 68 → 9 → 36 → 27 new funds/Q
New funds entering each quarter: 68 → 9 → 36 → 27. JBIO is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱
Early stage — 94% of holders entered in last year
■ 6% veterans
■ 0% 1-2yr
■ 94% new
Of 121 current holders: 114 (94%) entered in the past year, only 7 (6%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
✅
Strong quality — 26% AUM from major funds
26% from top-100 AUM funds
31 of 116 holders rank in the top 100 by AUM, accounting for 26% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.

Moderate Exit Risk
Exit risk score 6.3/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
