Company in Monrovia, United States
* 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 ($2.9m this quarter). Holder counts are more reliable. Shares outstanding: 48.5m as of 2023-07-28, 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 ≈ $52.62. Options: 13 managers hold calls ($11.7m notional), 15 hold puts ($22.2m).
