Smart Money Signals — ATI

Based on 782 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q

For 3 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

782 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 — +67% more funds vs a year ago

fund count last 6Q

+313 new funds entered over the past year (+67% 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

478 buying297 selling

Last quarter: 478 funds were net buyers (176 opened a brand new position + 302 added to an existing one). Only 297 were sellers (230 trimmed + 67 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+12 vs last Q)

💰

Price up while funds trimmed (+33% value, -1% shares)

Value

+32%

Last quarter: total value of institutional ATI holdings rose +33% 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.

📈

Growing discovery — still being found

108 → 89 → 148 → 164 → 176 new funds/Q

New funds entering each quarter: 89 → 148 → 164 → 176. A growing number of institutions are discovering ATI each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🏛️

Veteran-anchored — 54% veterans vs 35% newcomers

■ 54% veterans ■ 10% 1-2yr ■ 35% new

Entry-cohort mix of 815 holders: 444 (54%) are 2+ year veterans, 84 entered 1–2 years ago, and 287 (35%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

🏆

Elite ownership — 63% AUM from top-100 funds

63% from top-100 AUM funds

4.8

out of 10

Moderate Exit Risk

Exit risk score 4.8/10 — 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.
