* 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 ($7.3m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $80.98. Options: 13 managers hold calls ($67.8m notional), 11 hold puts ($28.5m).
