* 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 ($402.7m this quarter). Holder counts are more reliable. Shares outstanding: 142.1m as of 2026-07-16, 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 ≈ $509.44. Options: 33 managers hold calls ($354.4m notional), 32 hold puts ($438.6m).

The same trade is sometimes reported by more than one insider, such as a fund and the director who represents it; totals count it once.
