Smart Money Signals — ATMU

Based on 292 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added ATMU 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
292 hedge funds hold ATMU 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.
📶

Steady growth — +8% more funds vs a year ago

fund count last 6Q
+22 new funds entered over the past year (+8% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 54% buying

160 buying134 selling
Last quarter: 160 funds bought or added vs 134 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.
📈

More new buyers each quarter (+8 vs last Q)

new funds entering per quarter
Funds opening a new ATMU position: 35 → 31 → 44 → 52. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 25% long-term, 23% new

■ 25% conviction (2yr+) ■ 52% medium ■ 23% new
Of the 292 current holders: 72 (25%) held >2 years, 152 held 1–2 years, and 68 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
📈

Growing discovery — still being found

46 → 35 → 31 → 44 → 52 new funds/Q
New funds entering each quarter: 35 → 31 → 44 → 52. A growing number of institutions are discovering ATMU each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
📊

■ 23% veterans ■ 44% 1-2yr ■ 33% new
Of 299 current holders: 69 (23%) held 2+ years, 131 held 1–2 years, 99 (33%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
🏆

47% from top-100 AUM funds

3.7
out of 10
Low Exit Risk
Exit risk score 3.7/10 — 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.
