* 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 ($78.4m this quarter). Holder counts are more reliable. Shares outstanding: 61.1m as of 2024-08-05, 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 ≈ $541.10. Options: 18 managers hold calls ($79.3m notional), 19 hold puts ($97.6m).
