📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, 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
729 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.
