* 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 ($47.9m this quarter). Holder counts are more reliable. Shares outstanding: 60.3m as of 2025-08-04, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $548.86. Options: 14 managers hold calls ($89.0m notional), 13 hold puts ($87.2m).
