* 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 ($47.0m this quarter). Holder counts are more reliable. Shares outstanding: 72.5m as of 2025-08-01, 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 ≈ $189.32. Options: 20 managers hold calls ($167.8m notional), 29 hold puts ($271.6m).
