Form 13F is the quarterly report the SEC requires from institutional investment managers who exercise investment discretion over $100 million or more in Section 13(f) securities. Filed under Section 13(f) of the Securities Exchange Act of 1934, it discloses what a manager held in U.S. equities as of the last trading day of the prior calendar quarter.
Once a manager crosses the $100 million threshold, it must keep filing for that quarter and the following three, even if its assets later fall back below the threshold.
A Form 13F-HR lists each position with the issuer name, security class, CUSIP, market value, share count, investment discretion, and voting authority; a manager whose holdings are reported entirely by another filer submits a 13F-NT instead. The filing is due within 45 days of quarter-end. Because that lag runs up to 45 days and the form never discloses short positions, cash, or most derivatives, a 13F is a snapshot of a single past date rather than a live view of a portfolio. GeminIQ's Institutional Ownership feature tracks institutional ownership as a percentage of shares outstanding over time, aggregated from these filings.
A: Any institutional investment manager exercising investment discretion over $100 million or more in Section 13(f) securities must file, including investment advisers, mutual fund companies, pension funds, and insurance company investment divisions.
A: Form 13F is filed quarterly, within 45 days of the quarter's end. Because of that lag, the positions it discloses are already several weeks old by the time the filing becomes public.
A: No. Form 13F only discloses long positions in Section 13(f) securities. It does not report short positions, cash, bonds, or most derivatives, so a manager's full exposure is always larger than what its 13F reflects.
