* 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 ($2.1m this quarter). Holder counts are more reliable. Shares outstanding: 40.9m as of 2022-11-04, 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 ≈ $9.22. Options: 10 managers hold calls ($2.4m notional), 7 hold puts ($1.4m).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
