* 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 ($649.2k this quarter). Holder counts are more reliable. Shares outstanding: 66.9m as of 2025-04-29, 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 ≈ $6.15. Options: 6 managers hold calls ($1.1m notional), 5 hold puts ($1.1m).
