* 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 ($337.2k this quarter). Holder counts are more reliable. Shares outstanding: 115.5m as of 2024-11-04, 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 ≈ $4.47. Options: 4 managers hold calls ($39.9k notional), 3 hold puts ($25.0k).
