Smart Money Signals — ARM

Based on 751 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added ARM 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
751 hedge funds hold ARM 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 — +21% more funds vs a year ago

fund count last 6Q
+131 new funds entered over the past year (+21% 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.
🟡

Slight buying edge — 58% buying

442 buying324 selling
Last quarter: 442 funds bought or added vs 324 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 (+73 vs last Q)

new funds entering per quarter
Funds opening a new ARM position: 139 → 96 → 119 → 192. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 31% long-term, 30% new

■ 31% conviction (2yr+) ■ 39% medium ■ 30% new
Of the 751 current holders: 234 (31%) held >2 years, 291 held 1–2 years, and 226 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.
💰

Price up while funds trimmed (+28% value, -5% shares)

Value
+27%
Shares
-5%
Last quarter: total value of institutional ARM holdings rose +28% even though funds reduced share count by 5%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📈

Growing discovery — still being found

107 → 139 → 96 → 119 → 192 new funds/Q
New funds entering each quarter: 139 → 96 → 119 → 192. A growing number of institutions are discovering ARM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
📊

Mixed cohorts — 29% veterans, 34% new entrants

■ 29% veterans ■ 37% 1-2yr ■ 34% new
Of 817 current holders: 240 (29%) held 2+ years, 301 held 1–2 years, 276 (34%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
🏆

Elite ownership — 47% AUM from top-100 funds

47% from top-100 AUM funds
59 of 738 holders are among the 100 largest funds by AUM, controlling 47% of total institutional value in ARM. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.9
out of 10
Low Exit Risk
Exit risk score 3.9/10 — 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.
