* 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 ($18.2m this quarter). Holder counts are more reliable. Shares outstanding: 306.9m as of 2023-12-31, 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 ≈ $6.49. Options: 8 managers hold calls ($2.8m notional), 5 hold puts ($820.8k).
