What is an SEC 13F filing?
An SEC 13F is a quarterly report that large institutional investment managers file to disclose the U.S.-listed equity holdings they manage.
Who files a 13F
Institutional investment managers that exercise investment discretion over at least 100 million dollars in 13(f) securities must file a 13F every quarter.
Why it matters, and its limits
A 13F shows what big funds held at the end of a quarter, which is how people track hedge funds and other large managers. It is a delayed snapshot, it excludes short positions, and it omits most non-U.S. holdings, so it shows what a manager held, not necessarily what they hold now.
How QuantConomy surfaces it
QuantConomy reads 13F filings, links holdings to assets, and can raise an INSTITUTIONAL signal when a notable position changes.
Questions
How current is 13F data?
13F reports are filed up to 45 days after the end of each quarter, so the data is always somewhat delayed.
Does a 13F show short positions?
No. A 13F covers long positions in 13(f) securities and does not include short positions.
