Smart Money Signals — ATI

Based on 671 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added ATI 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
671 hedge funds hold ATI 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 — +59% more funds vs a year ago

fund count last 6Q
+248 new funds entered over the past year (+59% 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 — 62% buying

408 buying255 selling
Last quarter: 408 funds were net buyers (164 opened a brand new position + 244 added to an existing one). Only 255 were sellers (197 trimmed + 58 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+16 vs last Q)

new funds entering per quarter
Funds opening a new ATI position: 107 → 89 → 148 → 164. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

49% of holders stayed for 2+ years

■ 49% conviction (2yr+) ■ 21% medium ■ 30% new
331 out of 671 hedge funds have held ATI 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.
💰

Price up while funds trimmed (+23% value, -1% shares)

Value
+23%
Shares
-1%
Last quarter: total value of institutional ATI holdings rose +23% even though funds reduced share count by 1%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
🚀

Acceleration phase — new buyers rushing in

89 → 107 → 89 → 148 → 164 new funds/Q
New funds entering each quarter: 107 → 89 → 148 → 164. 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.
🏛️

Veteran-anchored — 59% veterans vs 30% newcomers

■ 59% veterans ■ 11% 1-2yr ■ 30% new
Entry-cohort mix of 704 holders: 412 (59%) are 2+ year veterans, 78 entered 1–2 years ago, and 214 (30%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 49% AUM from top-100 funds

49% from top-100 AUM funds
61 of 670 holders are among the 100 largest funds by AUM, controlling 49% of total institutional value in ATI. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

out of 10
Moderate Exit Risk
Exit risk score 4.5/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
