📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added SIBN 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
175 hedge funds hold SIBN 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 — +28% more funds vs a year ago
fund count last 6Q
+38 new funds entered over the past year (+28% 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 — 57% buying
104 buying79 selling
Last quarter: 104 funds bought or added vs 79 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 (+17 vs last Q)
new funds entering per quarter
Funds opening a new SIBN position: 34 → 35 → 16 → 33. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒
61% of holders stayed for 2+ years
■ 61% conviction (2yr+)
■ 21% medium
■ 18% new
107 out of 175 hedge funds have held SIBN 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.
💰
Price up while funds trimmed (+34% value, -0% shares)
Last quarter: total value of institutional SIBN holdings rose +34% even though funds reduced share count by 0%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📊
Peak discovery — momentum slowing
28 → 34 → 35 → 16 → 33 new funds/Q
New funds entering each quarter: 34 → 35 → 16 → 33. SIBN is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️
Deep conviction — 72% of holders stayed 2+ years
■ 72% veterans
■ 10% 1-2yr
■ 18% new
Of 179 current holders: 128 (72%) 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.
✅
Strong quality — 27% AUM from major funds
27% from top-100 AUM funds
32 of 175 holders rank in the top 100 by AUM, accounting for 27% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 3.7/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
