* 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 ($63.0k this quarter). Holder counts are more reliable. Shares outstanding: 62.7m 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 ≈ $3.16. Options: 8 managers hold calls ($2.2m notional), 6 hold puts ($3.0m).
