N-PORT vs 13F: fund holdings vs manager filings
On N-PORT vs 13F, the two SEC disclosures answer different questions about US funds. A Form N-PORT reports a single registered fund's complete portfolio, every position, across asset classes. A 13F reports an institutional manager's long US-listed equities across its whole business. N-PORT vs 13F is fund-complete versus manager-wide-but-narrow. This guide compares them, factually. It is not investment advice.
Definition
N-PORT versus a 13F
are two SEC windows into US fund positioning. An N-PORT is a registered fund's complete month-end portfolio with security identifiers. A 13F is any 100-million-dollar manager's long US-equity holdings. One is fund-specific and complete; the other is manager-wide and limited to long US stocks. Source: SEC.
What does an N-PORT show?
An N-PORT shows a registered fund's entire book: each holding with identifiers such as CUSIP, ISIN, and LEI, plus fund-level assets, returns, flows, and risk data. It is the fullest public view of what a US mutual fund or ETF actually owns, because it is not limited to one asset class.
What does a 13F show?
A 13F shows the long US-listed equities a manager held as of quarter-end, if that manager exercises discretion over at least 100 million US dollars in Section 13(f) securities. It is manager-wide, covering positions across all the funds and accounts the manager runs, but it excludes short positions, cash, most bonds, and non-US holdings.
How do N-PORT and a 13F compare?
| What to check | N-PORT | 13F |
|---|---|---|
| Who files | Registered funds (mutual funds, ETFs) | Managers over 100 million dollars in US equities |
| Scope | The fund's complete portfolio | The manager's long US-listed equities |
| Asset coverage | All asset classes | Long US equities and certain options only |
| Timing | Quarter-end holdings public within 60 days | Filed within 45 days of quarter-end |
| Best for | A fund's real, full holdings | Cross-manager US equity positioning |
60 days
Maximum lag before a fund's quarter-end N-PORT holdings become public, versus 45 days for a 13F

Which one should you read?
To see what a specific US fund actually holds, read its N-PORT, because it is complete. To compare positioning across many managers, or to spot where independent managers overlap, read the 13F, because it is the common denominator across the industry. Reading them together gives more than either alone.

Frequently asked questions
What is the difference between N-PORT and a 13F?
An N-PORT reports a registered US fund's complete portfolio, every position with identifiers. A 13F reports any institutional manager's long US-listed equities above a 100 million dollar threshold. N-PORT is fund-specific and complete; a 13F is manager-wide but limited to long US stocks. Source: SEC.
Which is more complete, N-PORT or a 13F?
N-PORT. It covers a fund's whole book across asset classes with security identifiers, while a 13F lists only long positions in US-listed equities and certain options. For a mutual fund's actual holdings, N-PORT is the fuller record. Source: SEC.
Which is more timely, N-PORT or a 13F?
A 13F is filed within 45 days of quarter-end. An N-PORT quarter-end report becomes public no later than 60 days after the period. Both are delayed snapshots, and the 13F publishes somewhat sooner. Source: SEC.
Can the same fund appear in both filings?
Yes. A registered fund files N-PORT for its complete portfolio, and its manager may also be captured in a 13F covering long US equities across the whole firm. The two serve different purposes and cover different scopes. Source: SEC EDGAR.
