* 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. Holder counts are more reliable. Implied quarter-end price ≈ $1.32. Options: 3 managers hold calls ($11.1k notional), 3 hold puts ($17.8k).
