📈
Buying streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds added CSL 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
779 hedge funds hold CSL 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
+58 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 — 53% buying
390 buying348 selling
Last quarter: 390 funds bought or added vs 348 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.
⚠️
Fewer new buyers each quarter (-15 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 103 → 92 → 122 → 107. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.

Elite ownership — 40% AUM from top-100 funds
40% from top-100 AUM funds
59 of 777 holders are among the 100 largest funds by AUM, controlling 40% of total institutional value in CSL. 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 3.5/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
