Coverage / method

Similarity metrics use the complete normalized common-stock issuer book for each manager in Q1 and Q2. The action tables provide a separate bounded evidence window. Each manager contributes up to 100 current Q2 common issuers by reported value. The window also includes featured issuers that the manager holds or changed. Both views exclude CALL and PUT rows.
