* 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 ($25.6k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $4.05. Options: 8 managers hold calls ($1.6m notional), 6 hold puts ($2.6m).
