📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added this stock 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 trade.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
158 hedge funds hold this stock 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 'crowded trade' — high ownership doesn't mean safe.
🚀
Fast accumulation — +24% more funds vs a year ago
fund count last 6Q
+31 new funds entered over the past year (+24% 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
94 buying73 selling
Last quarter: 94 funds bought or added vs 73 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 (+14 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 31 → 32 → 15 → 29. A growing number of new institutional buyers means the stock is still being discovered — the opportunity hasn't been fully priced in.
🔒
63% of holders stayed for 2+ years
■ 63% conviction (2yr+)
■ 20% medium
■ 18% new
99 out of 158 hedge funds have held this stock for over 2 years without selling. Long-term holders are harder to shake out during market dips — they represent a stable ownership base that reduces the risk of sudden mass selling.
💰
Price up while funds trimmed (+33% value, -0% shares)
Last quarter: total value of institutional SIBN holdings rose +33% 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
26 → 31 → 32 → 15 → 29 new funds/Q
New funds entering each quarter: 31 → 32 → 15 → 29. The stock is well-known in the hedge fund world but new entries are declining. The easy phase of institutional discovery may be behind us.
🏛️
Deep conviction — 73% of holders stayed 2+ years
■ 73% veterans
■ 11% 1-2yr
■ 16% new
Of 162 current holders: 118 (73%) 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.
📋
Smaller funds dominant — 18% top-100 AUM
18% from top-100 AUM funds
Only 28 of 158 current holders rank in the top 100 by AUM. The stock is held mostly by smaller and mid-sized funds — the largest institutional players haven't yet built significant positions.
Exit risk score 3.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
