How to read these SEC ownership signals

• Read each filing family separately: Form 13F, Schedules 13D/G, and Forms 3/4/5 answer different SEC disclosure questions and should not be blended into one ownership total.
• Use 13F values for visible U.S.-listed equity portfolios, 13D/G rows for large beneficial-owner stakes, and Forms 3/4/5 rows for reporting-owner positions and transactions.
• Open the linked research path when you need the filing, CIK, issuer, CUSIP, date, or source trail behind a value.
