* 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 ($5.4m this quarter). Holder counts are more reliable. Shares outstanding: 89.6m as of 2025-11-06, 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 ≈ $60.52. Options: 8 managers hold calls ($21.2m notional), 8 hold puts ($54.8m).
