AFFILIATED MANAGERS GROUP IN AMG
COM · Common Stock · CUSIP 008252108 · ISIN US0082521081
Global investment management 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 ($27.4m this quarter). Holder counts are more reliable. Shares outstanding: 31.9m as of 2024-05-03, 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 ≈ $167.40. Options: 4 managers hold calls ($4.2m notional), 4 hold puts ($2.5m).
