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 — the SEC's published list of qualifying stocks, ETFs, and certain equity options. 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 (Holdings Report) consists of a cover page, a summary page, and an Information Table listing each position: the issuer name, security class, CUSIP number, market value reported in thousands of dollars, share count, investment discretion, and voting authority. A manager whose holdings are reported entirely by another filer instead submits a Form 13F-NT, a notice confirming it has no positions of its own to report. The filing is due within 45 days of each quarter's end, and the SEC does not grant extensions.
Because the reporting lag runs up to 45 days and the form never discloses short positions, cash, or most derivatives, a 13F is a snapshot of what a manager held at a single past date rather than a live view of its current portfolio.
GeminIQ's Institutional Ownership feature tracks institutional ownership as a percentage of shares outstanding over time, aggregated from the quarterly Form 13F filings that name each stock.
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.
