* 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 ($9.9m this quarter). Holder counts are more reliable. Shares outstanding: 203.4m as of 2022-10-27, 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 ≈ $27.38. Options: 7 managers hold calls ($3.7m notional), 3 hold puts ($193.0k).
