* 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 ($97.6k this quarter). Holder counts are more reliable. Shares outstanding: 37.0m as of 2025-11-10, 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 ≈ $48.99. Options: 11 managers hold calls ($96.2m notional), 7 hold puts ($41.1m).
