Calculation and mechanics
Many funds under the Investment Company Act of 1940, including most classic stock and bond ETFs, must keep portfolio data on Form N-PORT for every month. Under the currently applicable rule, the reports of a fiscal quarter are filed with the SEC no later than 60 days after quarter end. The reports for the first two months generally stay non-public. The report for the third month becomes publicly available.
The filing contains structured data on the fund and its positions, including assets, liabilities, cash and details on individual investments such as name, identifiers, quantity and market value.
From this, among other things, the AUM and the top holdings of an ETF can be derived. The public filings are available via SEC EDGAR.
Distinction
Not every exchange-traded product is subject to Form N-PORT. Certain commodity, precious-metal or crypto trusts are not registered investment companies under the Investment Company Act of 1940 and are subject to other reporting obligations.
Provider websites often publish holdings and net assets more currently. N-PORT in turn has the advantage of a standardised, publicly available format.
