📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added ATLN 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
49 hedge funds hold ATLN 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 — +512% more funds vs a year ago
fund count last 6Q
+41 new funds entered over the past year (+512% 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 — 70% buying
35 buying15 selling
Last quarter: 35 funds were net buyers (19 opened a brand new position + 16 added to an existing one). Only 15 were sellers (9 trimmed + 6 sold completely). A clear majority buying is a strong confirmation signal.
📈
More new buyers each quarter (+14 vs last Q)
new funds entering per quarter
Funds opening a new ATLN position: 20 → 15 → 5 → 19. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔄
Mostly new holders — 61% entered in last year
■ 2% conviction (2yr+)
■ 37% medium
■ 61% new
Only 1 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.
💰
Value +255% but shares only +57% — price-driven
Last quarter: the total dollar value of institutional holdings rose +255%, but actual share count only changed +57%. 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.
📊
Peak discovery — momentum slowing
8 → 20 → 15 → 5 → 19 new funds/Q
New funds entering each quarter: 20 → 15 → 5 → 19. ATLN is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱
Early stage — 96% of holders entered in last year
■ 4% veterans
■ 0% 1-2yr
■ 96% new
Of 49 current holders: 47 (96%) entered in the past year, only 2 (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 — 35% AUM from major funds
35% from top-100 AUM funds
19 of 49 holders rank in the top 100 by AUM, accounting for 35% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.

Moderate Exit Risk
Exit risk score 6.1/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
