* 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 ($35.7m this quarter). Holder counts are more reliable. Shares outstanding: 53.3m as of 2024-10-25, 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 ≈ $103.06. Options: 2 managers hold calls ($257.7k notional), 7 hold puts ($34.6m).
