American nuclear energy and technology company
* 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 ($32.9m this quarter). Holder counts are more reliable. Shares outstanding: 91.5m as of 2023-08-01, 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 ≈ $71.55. Options: 11 managers hold calls ($14.4m notional), 9 hold puts ($7.0m).
