Form 13F
A quarterly report in which a large institutional manager lists the U.S. equity positions it held on the last day of the quarter.
Updated 2026-07-26
Managers above a size threshold file a 13F within forty-five days of each quarter end. The report lists positions in a defined set of publicly traded securities, with the issuer name, the CUSIP, the number of shares and the reported market value.
Two limits matter more than anything else in the report. It is a snapshot of the quarter end, not of today, and it arrives up to six weeks after that date, so by the time you read it the portfolio may already be different. And it covers only the securities on the required list — short positions, cash, bonds and most non-U.S. holdings are simply absent, so the report is not the manager's portfolio.
Comparing two consecutive 13Fs shows what changed between two quarter-end photographs. It does not show when, in what order, or at what price the changes happened.
