Fund Holdings (SEC N-PORT)

InfoTrie's fund holdings dataset reads the SEC's Form N-PORT data sets: what each US registered fund held at its quarter end, position by position, with the issuer's LEI, the security's ISIN, the value in US dollars and the share of the fund's net assets. Each holding is a dated edge of InfoTrie's entity graph, known from the day it was filed, so an amendment replaces the report it amends only from its filing date. On top of the positions, it answers who holds a security, what a fund holds through the funds it invests in, and what a management company's funds hold together.

Frequently asked questions

Is a fund that sold a security still listed as a holder?

No. Each fund is read from its latest report known on the day asked, for a period no older than 200 days: a fund that sold the security in its last report, or stopped reporting, is not a holder.

Are CUSIPs served?

No. Securities are named by ISIN; a CUSIP is only used to find the ISIN, and the answer says how the ISIN was found.

Are GICS sectors included?

No. Breakdowns use the country, issuer type and asset category as filed with the SEC.
