Form N-PORT is the monthly portfolio-holdings report that U.S. registered funds — mutual funds and ETFs — file with the SEC. Each quarter's third month is later released publicly, giving a detailed look inside fund portfolios.
Where 13F covers institutional managers, N-PORT covers registered funds (1940-Act mutual funds and ETFs) and is far more granular: it includes bonds, derivatives, currency exposure, and liquidity classifications — not just long U.S. equities.
Funds file every month, but only the report for the third month of each quarter is made public, on a roughly 60-day delay. It is the richest public window into what mutual funds and ETFs actually hold.
A bond ETF's N-PORT reveals its individual debt holdings and derivative positions — detail a 13F would never capture.
N-PORT extends the EDGAR cluster from "what managers hold" to "what funds hold," including fixed income — a natural expansion of the same acquisition infrastructure.
