* 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 ($82.0k this quarter). Holder counts are more reliable. Shares outstanding: 235.6m 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 ≈ $11.23. Options: 30 managers hold calls ($178.6m notional), 31 hold puts ($138.2m).
