The authoritative place to find 13F filings is the SEC’s EDGAR database, which holds every Form 13F submitted by institutional investment managers overseeing at least $100 million in qualifying securities.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F Third-party platforms such as WhaleWisdom and Dataroma repackage the same EDGAR data into friendlier interfaces, but EDGAR is the source they all draw from and the tie-breaker when numbers disagree.
Searching EDGAR for a Fund’s 13F
EDGAR stands for the Electronic Data Gathering, Analysis, and Retrieval system. Managers are required to submit their filings through it, so the record is comprehensive and unfiltered.2U.S. Securities and Exchange Commission. Form 13F Data Sets
The current tool is the EDGAR full-text search at sec.gov/edgar/search/, which covers electronic filings back to 2001. Older guides that describe a separate “Company Search” page with a “Filing Type” filter box are out of date.
Start by entering the firm’s name, ticker, or CIK number in the search bar. The CIK is a unique numeric identifier the SEC assigns to every filer. If you don’t know it, the SEC’s dedicated lookup at sec.gov/search-filings/cik-lookup lets you search by name.
Once the firm is entered, expand the filing category options and check the 13F form types. The interface lists 13F-HR, 13F-NT, and their variants individually. Narrowing by date range helps, since filings accumulate over years and you usually want the most recent quarter. The results list shows each filing with its date and form type.
Click into a specific filing to see its documents. The primary document is typically an HTML or XML file containing the holdings table. The HTML version opens directly in the browser and displays security names, share counts, and market values in a formatted table.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F
Which 13F Form Type to Open
EDGAR returns several 13F variants and they are not interchangeable.
- 13F-HR is the Holdings Report. This is the filing with the actual list of securities and the one you want for portfolio analysis.
- 13F-NT is a Notice, filed when the holdings are reported by another entity, often a parent company filing on behalf of subsidiaries. It contains no holdings data; look for the related 13F-HR filed by the reporting entity.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F
- 13F-HR/A is an amendment. A “restatement” amendment supersedes the original entirely, while an “adding new holdings entries” amendment supplements it, often because a confidential treatment request expired.3SEC.gov. Form 13F Information Required of Institutional Investment Managers
When both an original 13F-HR and a later 13F-HR/A exist for the same quarter, check the amendment. A restatement replaces the original, so the earlier numbers are no longer accurate.
Reading the Information Table
The core of every 13F-HR is the Information Table, listing each qualifying security the manager held on the last trading day of the quarter. A few columns cause confusion:
- Issuer Name and Title of Class identify the company and the specific security, such as common stock, a call, a put, or a convertible note.
- CUSIP is a nine-character identifier useful for cross-referencing across filings from different managers.
- Market Value is the dollar value as of the last trading day of the quarter, rounded to the nearest thousand. The trailing three zeros are omitted, so a figure of “15,230” means $15,230,000.4Reginfo.gov. Form 13F Instructions
- SH/PRN is the number of shares (SH) or, on debt securities, the principal amount (PRN).4Reginfo.gov. Form 13F Instructions
- Put/Call flags option positions; blank means straight equity.4Reginfo.gov. Form 13F Instructions
- Investment Discretion shows whether the manager has sole, shared, or no voting and investment authority over the position.
The values-in-thousands convention trips up first-time readers. If a third-party site’s numbers are off from EDGAR by a factor of 1,000, that’s usually why.
Third-Party Aggregators
Several private platforms pull 13F data from EDGAR and rebuild it for quicker analysis. WhaleWisdom and Dataroma are two of the better-known ones. They offer side-by-side comparisons of multiple funds, historical position tracking, alerts when a manager adds or drops a holding, and portfolio-level analytics like sector concentration.
Pricing varies. WhaleWisdom provides the most recent two years of 13F data at no cost, with paid subscriptions unlocking data back to 2001 along with tools like backtesting and API access. Enterprise pricing typically requires contacting the platform directly.
The trade-off is freshness and completeness. Aggregators process filings on their own schedule, so there can be a lag between when a filing appears on EDGAR and when it lands on the aggregator. Amendments are a particular weak spot; some platforms are slow to incorporate 13F-HR/A filings, meaning what you see may reflect the original rather than the corrected version. For casual monitoring, aggregators are fine. For any decision where accuracy matters, verify against EDGAR.
What the Filings Don’t Show
Finding the filing is one thing. Reading it as a complete picture of what a fund is doing will mislead you, because several categories of holdings never appear.
Short positions are excluded entirely. The SEC’s instructions tell managers not to include shorts and not to net them against long positions in the same security. A fund that is long 500,000 shares and short 400,000 shares of the same stock reports the full 500,000-share long position, making the disclosure look bullish when the net exposure is close to flat. Written options (puts or calls the manager sold) are also excluded, because they represent short exposure.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F
Only securities on the SEC’s Official List of Section 13(f) Securities get reported. That list primarily covers U.S. exchange-traded stocks, closed-end funds, ETFs, and certain convertible debt and warrants. Shares that trade exclusively on foreign exchanges are excluded, as are mutual fund shares. The SEC publishes an updated list each quarter.5U.S. Securities and Exchange Commission. Official List of Section 13(f) Securities
Then there is the timing lag. Managers have 45 days after quarter-end to file, so a public 13F may reflect positions that are six weeks old or older.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F Active hedge funds can turn over a meaningful portion of their portfolio in that window, so copying a manager’s positions the day a filing drops assumes holdings that may already be gone.
Confidential Treatment Requests
Even on filings that do publish, some holdings can be missing. Under Section 13(f)(3) of the Securities Exchange Act, the SEC can allow a manager to temporarily withhold specific positions from the public version if disclosure would harm the manager’s competitive position.6U.S. Securities and Exchange Commission. Section 13(f) Confidential Treatment Requests
The most common basis is that the manager is still actively building or unwinding a position and public disclosure would invite front-running. The SEC recognizes this along with open risk-arbitrage and block-positioning strategies.6U.S. Securities and Exchange Commission. Section 13(f) Confidential Treatment Requests
Confidential treatment is not permanent. When it expires or is denied, the manager must file an amended 13F (a 13F-HR/A) within six business days to disclose the previously hidden holdings.3SEC.gov. Form 13F Information Required of Institutional Investment Managers A position missing from the original may surface in an amendment weeks or months later, so serious research on a specific fund is worth checking for amendments.
2026 Filing Deadlines
Filings are due within 45 days after the end of each calendar quarter.1Securities and Exchange Commission. Frequently Asked Questions About Form 13F When a deadline falls on a weekend or federal holiday, it shifts to the next business day. For 2026 that produces:
- Q4 2025 holdings: due February 17, 2026 (the standard February 14 date falls on a Saturday, and Monday is Presidents’ Day).1Securities and Exchange Commission. Frequently Asked Questions About Form 13F
- Q1 2026 holdings: due May 15, 2026.
- Q2 2026 holdings: due August 14, 2026.
- Q3 2026 holdings: due November 16, 2026 (November 14 is a Saturday).
Most managers file close to the deadline rather than early, so the days immediately after each due date are when the bulk of new filings appear on EDGAR. If you’re tracking a particular fund, a calendar reminder on those dates beats checking repeatedly through the quarter.
