Buying streak — 3 quarters in a row
For 3 consecutive quarters, more hedge funds added AHL 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
122 hedge funds hold AHL 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 — +12100% more funds vs a year ago
fund count last 6Q
+121 new funds entered over the past year (+12100% 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 — 77% buying
93 buying28 selling
Last quarter: 93 funds were net buyers (45 opened a brand new position + 48 added to an existing one). Only 28 were sellers (15 trimmed + 13 sold completely). A clear majority buying is a strong confirmation signal.
⚠️
Fewer new buyers each quarter (-16 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 0 → 65 → 61 → 45. 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 — 89% entered in last year
■ 2% conviction (2yr+)
■ 9% medium
■ 89% new
Only 3 funds (2%) 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.
🚀
Acceleration phase — new buyers rushing in
0 → 0 → 65 → 61 → 45 new funds/Q
New funds entering each quarter: 0 → 65 → 61 → 45. 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 — 86% of holders entered in last year
■ 14% veterans
■ 0% 1-2yr
■ 86% new
Of 122 current holders: 105 (86%) entered in the past year, only 17 (14%) 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.
📋
Smaller funds dominant — 4% AUM from top-100
4% from top-100 AUM funds
27 of 122 holders rank in the top 100 by AUM, but together hold only 4% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
Exit risk score 7.2/10 — 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.
