📈
Buying streak — 1 quarter in a row
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 buying323 selling
Last quarter: 442 funds bought or added vs 323 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: 138 → 96 → 119 → 192. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

■ 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)
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 → 138 → 96 → 119 → 192 new funds/Q
New funds entering each quarter: 138 → 96 → 119 → 192. A growing number of institutions are discovering ARM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

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 — 57% AUM from top-100 funds
57% from top-100 AUM funds
58 of 738 holders are among the 100 largest funds by AUM, controlling 57% 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.
Exit risk score 3.9/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
