What is an N-PORT filing? Fund holdings, explained
What is an N-PORT filing? Form N-PORT is the portfolio-holdings report that US registered funds, meaning most mutual funds and exchange-traded funds, file with the Securities and Exchange Commission (SEC). It lists what the fund actually held, position by position, at the end of the period. An N-PORT filing is how the public sees a US fund's real holdings, and it is the SEC form that replaced the older Form N-Q. It is not investment advice.
Definition
An N-PORT filing
is the SEC portfolio-holdings report filed by US registered funds such as mutual funds and ETFs. It discloses the fund's complete month-end holdings with security identifiers, plus fund-level financials and risk data. It replaced Form N-Q and is the fullest public view of a fund's book. Source: SEC.
Who files an N-PORT filing?
Registered management investment companies file Form N-PORT. In practice that is most US mutual funds and ETFs. The report covers the fund's entire portfolio, so it is broader than a 13F, which captures only a manager's long US-listed equities.
How current is N-PORT data?
Under the rules in force today, a fund files N-PORT for each fiscal quarter within 60 days of quarter-end, and the complete holdings for the first and third fiscal quarters are made public on EDGAR no later than 60 days after the period. So the earliest you can read a fund's holdings, they are already about two months old. The second and fourth quarter holdings reach the public through the fund's shareholder reports on Form N-CSR.

What changed in 2024, and why it is not live yet
In August 2024 the SEC adopted amendments that would require funds to file N-PORT every month within 30 days of month-end, with each report made public after a delay. In 2025 the SEC delayed the compliance dates: 17 November 2027 for fund groups with 1 billion dollars or more in assets, and 18 May 2028 for smaller groups. Until those dates, the quarterly regime above is what applies, so any current N-PORT read follows the 60-day rule.
How N-PORT compares to a 13F
N-PORT and the 13F are the two main windows into US fund positioning, and they are not the same. An N-PORT shows a single registered fund's complete book; a 13F shows any manager's long US equity holdings across its whole business. The difference between N-PORT and a 13F matters when you want a fund's real holdings rather than a manager's US equity slice.
