📉
Selling streak — 3 quarters in a row
For 3 consecutive quarters, more hedge funds reduced or closed their ATOS positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊
High ownership — 72% of 3.0Y peak
72% of all-time peak
61 funds currently hold this stock — 72% of the 3.0-year high of 85 funds (reached 2024 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉
Outflows — 26% fewer funds vs a year ago
fund count last 6Q
21 fewer hedge funds hold ATOS compared to a year ago (-26% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡
Slight buying edge — 56% buying
31 buying24 selling
Last quarter: 31 funds bought or added vs 24 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 — ~11 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 11 → 25 → 8 → 11. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒
59% of holders stayed for 2+ years
■ 59% conviction (2yr+)
■ 16% medium
■ 25% new
36 out of 61 hedge funds have held ATOS 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.
💎
Buying through price weakness — shares +13%, value -23%
Last quarter: funds added +13% more shares while total portfolio value only changed -23%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
⚠️
Saturation — most institutions already know this story
8 → 11 → 25 → 8 → 11 new funds/Q
New funds entering each quarter: 11 → 25 → 8 → 11. Far fewer institutions are entering now vs. a year ago. When the pool of potential new buyers shrinks this fast, future price support from institutional inflows weakens significantly.
🏛️
Deep conviction — 68% of holders stayed 2+ years
■ 68% veterans
■ 12% 1-2yr
■ 20% new
Of 65 current holders: 44 (68%) 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.
🏆
Elite ownership — 58% AUM from top-100 funds
58% from top-100 AUM funds
16 of 61 holders are among the 100 largest funds by AUM, controlling 58% of total institutional value in ATOS. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 2.2/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
