What is a 13F filing?
A 13F is a report that large investors must file with the SEC every quarter. It lists the US stocks they owned at the end of the quarter. Any firm that manages more than 100 million dollars has to file one within 45 days.
Who has to file
Hedge funds, asset managers, banks, and other large investors. The rule covers any firm with more than 100 million dollars in US stocks.
What it shows
The US stocks the firm held at the end of the quarter, the number of shares, and the dollar value of each position.
What it does not show
It leaves out short bets, cash, bonds, and most foreign stocks. It is also delayed by up to 45 days, so it is a snapshot of the past, not a live feed of trades.
Why it matters
13F filings are the main way regular investors can see what famous investors are buying and selling. You can follow a manager you respect and learn from how they build a portfolio.
