📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added OSUR 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.
🔻
Below peak — only 63% of 3.0Y high
63% of all-time peak
Only 142 funds hold OSUR today versus a peak of 227 funds at 2024 Q1 — just 63% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉
Outflows — 21% fewer funds vs a year ago
fund count last 6Q
37 fewer hedge funds hold OSUR compared to a year ago (-21% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡
Slight buying edge — 57% buying
76 buying58 selling
Last quarter: 76 funds bought or added vs 58 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.
📈
More new buyers each quarter (+11 vs last Q)
new funds entering per quarter
Funds opening a new OSUR position: 16 → 12 → 15 → 26. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

■ 67% conviction (2yr+)
■ 20% medium
■ 13% new
95 out of 142 hedge funds have held OSUR 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.
💎
Buying through price weakness — shares -6%, value -26%
Last quarter: funds added -6% more shares while total portfolio value only changed -26%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈
Growing discovery — still being found
30 → 16 → 12 → 15 → 26 new funds/Q
New funds entering each quarter: 16 → 12 → 15 → 26. A growing number of institutions are discovering OSUR each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️
Veteran-anchored — 73% veterans vs 17% newcomers
■ 73% veterans
■ 9% 1-2yr
■ 17% new
Entry-cohort mix of 143 holders: 105 (73%) are 2+ year veterans, 13 entered 1–2 years ago, and 25 (17%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅
Strong quality — 35% AUM from major funds
35% from top-100 AUM funds
37 of 141 holders rank in the top 100 by AUM, accounting for 35% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 1.5/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
