get13FHolders

Free

Find institutional managers whose 13F-HR reports a given security (by CUSIP) for a quarter, with each manager's shares and value. Uses EDGAR full-text search, so it returns a sample of holders (not ranked by position size) plus the approximate total number of filers; use get13FHoldings to check one specific manager. Get the CUSIP from get13FHoldings output or a ticker lookup tool.
