* 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 ($71.4m this quarter). Holder counts are more reliable. Shares outstanding: 163.2m as of 2025-12-31, 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 ≈ $103.95. Options: 13 managers hold calls ($117.1m notional), 10 hold puts ($64.6m).

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.
