* 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 ($38.8m this quarter). Holder counts are more reliable. Shares outstanding: 57.4m as of 2025-07-30, 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 ≈ $294.22. Options: 18 managers hold calls ($129.9m notional), 11 hold puts ($35.5m).

Their holding: how much the trade added to or took from the insider's holding (direct, or the trust or fund named).
