What is a 13F filing?
Every quarter, funds managing over $100 million must disclose their US stock holdings to the SEC. That document is the 13F: a public map of where smart money really sits.
45 days after each quarter ends you can see what Berkshire, Citadel, Vanguard, BlackRock and thousands of other funds bought and sold. It's public and free — but the raw data is hard to read. InsiderFlow translates it for you.
What a 13F does NOT show
Only long positions in US stocks, with a ~45-day delay. No shorts, bonds or cash. Read it as a trend, not an instant signal.
