📈
Buying streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds added ANAB 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
174 hedge funds hold ANAB 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 — 50% buying
88 buying87 selling
Last quarter: 88 funds bought or added vs 87 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.
➡️
Steady new buyers — ~35 new funds per quarter
new funds entering per quarter

■ 57% conviction (2yr+)
■ 24% medium
■ 19% new
100 out of 174 hedge funds have held ANAB 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 (+46% value, -7% shares)
Last quarter: total value of institutional ANAB holdings rose +46% even though funds reduced share count by 7%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
➡️
Steady discovery — ~35 new funds/quarter
25 → 42 → 28 → 33 → 35 new funds/Q
New funds entering each quarter: 42 → 28 → 33 → 35. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️
Deep conviction — 66% of holders stayed 2+ years
■ 66% veterans
■ 12% 1-2yr
■ 22% new
Of 179 current holders: 118 (66%) 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 — 21% AUM from major funds
21% from top-100 AUM funds
30 of 174 holders rank in the top 100 by AUM, accounting for 21% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 3.8/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
