📈
Buying streak — 5 quarters in a row
For 5 consecutive quarters, more hedge funds added CALX 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
311 hedge funds hold CALX 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 — +29% more funds vs a year ago
fund count last 6Q
+70 new funds entered over the past year (+29% 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
184 buying132 selling
Last quarter: 184 funds bought or added vs 132 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 (+9 vs last Q)
new funds entering per quarter
Funds opening a new CALX position: 36 → 64 → 49 → 58. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

Strong quality — 39% AUM from major funds
39% from top-100 AUM funds
