How to Find SEC Form 13F Filings
TL;DR
- Use SEC EDGAR’s full-text and company searches to locate a manager’s latest Form 13F, then verify whether you are viewing the current 13F-HR, an amendment, or an information table instead of the holdings list itself.
- Read each filing by quarter-end snapshot: shares and fair market value reflect the last trading day of the quarter, not a buy or sell transaction on another date.
- Treat 13F data as a public disclosure of long reportable positions; it does not show short positions, many derivatives, or every account managed by the filer.
- For a product view of institutional and insider disclosures on a stock page, see Apple (AAPL).
- For background on how Form 13F compares with Forms 3, 4 and 5, see the insider vs institutional filing guide.
What Form 13F is meant to disclose
Form 13F is a quarterly report for institutional investment managers who exercise investment discretion over accounts holding at least $100 million in Section 13(f) securities on the last trading day of any month during a calendar year SEC Form 13F FAQ. Section 13(f) securities include U.S.-exchange-listed equities, certain ETFs and closed-end funds, certain convertible debt securities, and securities on the SEC’s official list. Ordinary open-end mutual funds are generally not reportable SEC Form 13F FAQ.
The form reveals the names of issuers, security titles and classes, CUSIPs, share counts or principal amounts, fair market values, investment discretion, and voting authority SEC Form 13F FAQ. Because the information is filed by the manager, not by the issuer, it is a view of portfolio construction rather than corporate insider trading.
How to search EDGAR for a 13F filing
EDGAR is the SEC’s free filing database. For direct filing searches, start at SEC EDGAR and use the company or fund search to find a manager’s filings. If you know the issuer rather than the manager, search by ticker or company name and then filter results to Form 13F. The SEC also provides programmatic access through the EDGAR API and guidance in EDGAR Search Assistance.
When you open a manager’s filings, look for the form type 13F-HR. That is the standard quarterly holdings report. Amendments, cover pages, or supporting information tables may appear alongside it, so confirm you are viewing the holdings section before drawing conclusions from a table.
Filers, CIKs, and filing periods
Institutional managers file by calendar quarter. Once the $100 million threshold is met, they generally file within 45 days after the quarter-end SEC Form 13F FAQ. Each filing is tied to a Central Index Key, or CIK, which identifies the manager across EDGAR searches and archives. If you are matching multiple quarters for the same manager, use the CIK rather than a slightly changed display name.
Filing periods matter because 13F reports are quarter-end snapshots, not ongoing transaction logs. A position shown in a March 31 filing reflects the manager’s holdings on that date, not when the shares were bought or sold.
13F-HR versus amendments and information tables
The 13F-HR form type is the primary quarterly holdings report. Amendments or related documents may correct or supplement earlier filings. In addition, some managers file information tables that summarize holdings in machine-readable form. The plain holdings list inside the main 13F-HR remains the most direct source for issuer names, share counts, and fair market values.
If a filing includes supporting documents, inspect them to see whether they amend prior-period values or add detail to the current quarter. Otherwise you may mistake an information summary for the holdings table itself.
What institutional holdings reveal and do not reveal
Form 13F reveals long positions in reportable Section 13(f) securities held as of quarter-end SEC Form 13F FAQ. This data is useful for understanding which large managers hold a security and how large those holdings are.
The form does not reveal short positions, many derivatives, every account managed by the filer, or the timing of trades within the quarter. The SEC’s guidance for investors emphasizes that insider filings are separate from institutional holdings: Forms 3, 4 and 5 disclose corporate insider transactions, while Form 13F discloses portfolio positions Investor.gov. A 13F filing therefore shows public disclosure of long reportable positions, not proof of a buy or sell decision on any specific date.
Common errors and fixes
| Error | Cause | Fix | Source |
|---|---|---|---|
| Treating 13F as a trade report | The filing is a quarter-end position snapshot | Read the filing date and period-end date; shares and value reflect the last day of the quarter, not trade dates | SEC Form 13F FAQ |
| Confusing 13F with insider filings | 13F covers institutional managers, not corporate insiders | Use Forms 3, 4 and 5 for insider transactions and Form 13F for institutional positions | Investor.gov |
| Opening the wrong document in a filing | Amendments, cover pages, and information tables can accompany 13F-HR | Confirm you are viewing the holdings list within the primary 13F-HR filing | SEC EDGAR Search Assistance |
| Assuming all positions are disclosed | Short positions, certain derivatives, and some fund types are excluded | Read the form scope as long reportable positions only | SEC Form 13F FAQ |
FAQ
Q: Where do I start searching for a manager’s 13F filings?
Go to SEC EDGAR and search by manager name, CIK, or ticker. Filter results to Form 13F and then open the latest 13F-HR. The SEC also offers EDGAR API access for programmatic lookups.
Q: How do I tell whether a filing is current or amended?
Check the form type and filing date. 13F-HR is the standard quarterly report. Amendments or supporting tables may carry different document names within the same submission. Use the filing date to confirm the quarter being reported.
Q: What is the $100 million threshold in plain terms?
An institutional investment manager must file Form 13F if it exercises investment discretion over accounts holding at least $100 million in Section 13(f) securities on the last trading day of any month in a calendar year SEC Form 13F FAQ. Once triggered, the manager generally files four quarterly reports within 45 days after each quarter-end.
Q: Does Form 13F show short positions or options?
No. Form 13F reports long reportable positions. Short positions and many derivatives are not disclosed in the same manner SEC Form 13F FAQ.
Q: Is a 13F holding a recommendation to buy or sell?
No. A 13F filing is a public disclosure of a quarter-end position. It does not constitute investment advice, a prediction of future performance, or a buy or sell recommendation.
Q: How can I see this data inside the product?
- FundamentalRadar surfaces institutional holdings from SEC EDGAR on US stock pages such as Apple (AAPL), alongside valuation ratios, profitability metrics, and financial statements.
Q: What is the difference between an information table and the holdings list?
An information table may summarize holdings in a structured format, but the main 13F-HR filing contains the direct holdings list. If the table is unreadable or incomplete, return to the primary filing document for issuer names, share counts, and fair market values.
Q: Can a natural person file Form 13F?
A natural person investing solely for their own account is generally excluded. An individual who manages another person’s or entity’s account may be classified as an institutional manager and required to file SEC Form 13F FAQ.
