# What is a 13F filing?

Canonical: https://sec-api.dev/questions/what-is-a-13f-filing

> Form 13F-HR is the quarterly report in which institutional investment managers with $100 million or more in Section 13(f) securities list their long positions at quarter end. It is due 45 days after the quarter ends and does not show shorts, most non-U.S. holdings or trades during the quarter.

Each filing has an information table of positions with CUSIP, value and shares; the API parses one table at a time without reconciling across filings.
