SEC Form 13F reports quarter-end Section 13(f) securities over which qualifying institutional investment managers exercise investment discretion.
SEC Form 13F is the quarterly holdings report required from an institutional investment manager that exercises investment discretion over at least $100 million in securities on the SEC’s Official List of Section 13(f) Securities. The filing identifies reportable quarter-end positions, not every asset, trade, short position, or economic exposure in the manager’s portfolio.
Form 13F can help investors study institutional ownership, but it is delayed and incomplete by design. It should not be treated as a live portfolio, a transaction ledger, or a recommendation to copy a manager.
An institutional investment manager can be an entity investing for its own account or a person or entity exercising investment discretion over another account. Depending on the facts, the definition can include investment advisers, banks, insurance companies, broker-dealers, pension funds, corporations managing their own portfolios, trustees, and foreign managers using U.S. interstate commerce.
The filing obligation generally depends on two tests:
The threshold is not simply “$100 million under management.” Cash, private investments, many bonds, open-end mutual funds, foreign ordinary shares not on the Official List, and other assets may be outside the calculation.
Under the SEC’s current guidance, a manager that first meets the threshold during a calendar year generally files:
Each report is generally due within 45 days after quarter-end, adjusted when the deadline falls on a weekend or federal holiday. The obligation can continue in later years if the manager continues to meet the threshold test.
This structure means a public filing can describe positions that are already six weeks old. A manager may have increased, reduced, hedged, or exited a position before the filing becomes public.
The information table commonly includes:
| Field | What it tells the reader |
|---|---|
| Issuer and security class | The company or fund and the type of reportable security |
| CUSIP | The identifier used for the reported security |
| Quarter-end fair market value | Reported value as of the final trading day of the quarter |
| Shares or principal amount | Position size under the form’s reporting conventions |
| Put/call indicator | Whether a reported option position is a put or call held by the manager |
| Investment discretion | Whether discretion is sole, shared-defined, or shared-other |
| Other manager | Another qualifying manager connected to shared discretion |
| Voting authority | Reported sole, shared, or no voting authority |
The filing summary also identifies the reporting manager, report type, number of other included managers, number of information-table entries, and aggregate reported value.
The SEC publishes an Official List after each calendar quarter. It primarily includes U.S. exchange-traded stocks, exchange-traded funds, closed-end fund shares, and certain equity options, warrants, and convertible securities.
| Often reportable when on the Official List | Generally not shown as ordinary Form 13F positions |
|---|---|
| U.S. exchange-traded common shares | Cash and cash equivalents |
| Many ETFs and closed-end funds | Open-end mutual fund shares |
| Certain convertible securities and warrants | Many bonds and private securities |
| Put and call options held by the manager | Written options and short equity positions |
| Eligible depositary receipts | Foreign ordinary shares absent from the Official List |
A portfolio can therefore have substantial leverage, short exposure, swaps, private assets, or non-U.S. positions that Form 13F does not reveal.
Check the manager’s legal name, filing number, amendment status, period of report, and whether holdings are reported directly or through another included manager.
The filing date is not the portfolio measurement date. Compare holdings using the period of report and remember the 45-day publication lag.
Stock splits, mergers, spin-offs, ticker or CUSIP changes, conversions, and fund reorganizations can make raw share-count changes misleading.
Affiliates or subadvisers can share discretion. A position can move between reporting arrangements without representing an open-market trade.
An option position is not equivalent to owning the underlying shares. Form 13F does not provide the full strike, expiration, premium, or offsetting portfolio needed to reconstruct exposure.
An amended filing can correct or restate the information table. Information initially withheld under confidential treatment may become public later.
Assume a manager reports 1,000,000 shares of Company A at March 31 and 600,000 shares at June 30. A screen labels the change “sold 400,000 shares.”
That may be correct, but Form 13F alone does not prove it. A careful review asks:
Even if the manager did sell 400,000 shares, the form does not disclose motive. The change could reflect valuation, risk limits, client flows, tax management, index rebalancing, or a mandate change.
| Filing | Reporter | Main purpose |
|---|---|---|
| Form 13F | Qualifying institutional investment manager | Quarter-end reportable holdings under investment discretion |
| SEC Form 4 | Covered director, officer, or more-than-10% owner | Most changes in Section 16 beneficial ownership |
| Schedule 13D or 13G | Person or group crossing applicable beneficial-ownership thresholds | Significant beneficial ownership and, depending on the schedule, intent or eligibility information |
| Proxy Statement | Company soliciting shareholder votes | Governance, voting, compensation, and specified ownership disclosure |
These forms use different definitions, thresholds, timing, and purposes. Holdings shown on one form do not necessarily reconcile mechanically with another.
For fund or manager analysis, the filing should be combined with strategy documents, investor reports, risk disclosures, and current portfolio information where available.
The SEC’s Form 13F frequently asked questions explain the current threshold test, filing cycle, Official List, reportable positions, options, shared discretion, confidential treatment, and deadlines. The SEC’s official Form 13F page links to the form and instructions. Investor.gov’s EDGAR research guide places Form 13F within the broader ownership-reporting system.
