Buying streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds added ABVX 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
238 hedge funds hold ABVX 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 — +429% more funds vs a year ago
fund count last 6Q
+193 new funds entered over the past year (+429% 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.
🟢
More buyers than sellers — 69% buying
176 buying79 selling
Last quarter: 176 funds were net buyers (100 opened a brand new position + 76 added to an existing one). Only 79 were sellers (52 trimmed + 27 sold completely). A clear majority buying is a strong confirmation signal.
⚠️
Fewer new buyers each quarter (-29 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 7 → 7 → 129 → 100. 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 — 79% entered in last year
■ 6% conviction (2yr+)
■ 15% medium
■ 79% new
Only 14 funds (6%) 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.
💰
Value +96% but shares only +15% — price-driven
Last quarter: the total dollar value of institutional holdings rose +96%, but actual share count only changed +15%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
🚀
Acceleration phase — new buyers rushing in
10 → 7 → 7 → 129 → 100 new funds/Q
New funds entering each quarter: 7 → 7 → 129 → 100. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🌱
Early stage — 82% of holders entered in last year
■ 4% veterans
■ 14% 1-2yr
■ 82% new
Of 265 current holders: 218 (82%) entered in the past year, only 11 (4%) 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 — 21% AUM from major funds
21% from top-100 AUM funds
24 of 238 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 7.0/10 — multiple crowding signals converge. Institutional ownership is at 100% of its all-time high — near peak crowding. Crowded trades can unwind fast — a single catalyst can trigger a cascade.
