Smart Money Signals — ATOS

Based on 31 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 7 quarters in a row

last 6Q
For 7 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.
🔻

Below peak — only 36% of 3.0Y high

36% of all-time peak
Only 31 funds hold ATOS today versus a peak of 85 funds at 2024 Q3 — just 36% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉

Outflows — 61% fewer funds vs a year ago

fund count last 6Q
49 fewer hedge funds hold ATOS compared to a year ago (-61% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠

More sellers than buyers — 47% buying

14 buying16 selling
Last quarter: 16 funds reduced or exited vs 14 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
➡️

Steady new buyers — ~6 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 8 → 12 → 8 → 6. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

61% of holders stayed for 2+ years

61% conviction (2yr+) 13% medium 26% new
19 out of 31 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 +14%, value -60%

Value
-59%
Shares
+14%
Last quarter: funds added +14% more shares while total portfolio value only changed -60%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊

Peak discovery — momentum slowing

25 → 8 → 12 → 8 → 6 new funds/Q
New funds entering each quarter: 8 → 12 → 8 → 6. ATOS is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Veteran-anchored — 66% veterans vs 25% newcomers

66% veterans 9% 1-2yr 25% new
Entry-cohort mix of 32 holders: 21 (66%) are 2+ year veterans, 3 entered 1–2 years ago, and 8 (25%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 51% AUM from top-100 funds

51% from top-100 AUM funds
13 of 31 holders are among the 100 largest funds by AUM, controlling 51% 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.
1.0
out of 10
Low Exit Risk
Exit risk score 1.0/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
