OperationId:sec_13f_holders_of_cusip

Reverse lookup: every 13F filer reporting a position in the given CUSIP for the latest quarter. Each holder entry includes the manager name, CIK, share count, market value, voting authority, and put/call flag. Useful for institutional ownership snapshots of any US-traded security. Requires the canonical 9-character CUSIP (case-insensitive); 8-character form is rejected because SEC bulk data only stores the 9-character canonical form (8 significant + check digit).
