* 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 ($236.3m this quarter). Holder counts are more reliable. Shares outstanding: 312.4m as of 2025-07-31, 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 ≈ $322.59. Options: 50 managers hold calls ($2.2bn notional), 50 hold puts ($3.0bn).
