* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($1.1m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $81.20. Options: 8 managers hold calls ($119.6m notional), 7 hold puts ($6.0m).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
