Filings can be up to 45 days old. Not investment advice.
How this works
Each fund's latest 13F-HR (long U.S. stock positions, filed up to 45 days after quarter end) is compared with its previous one. New = not held last quarter; added / cut = share count up or down; sold = position gone. Options and bonds aren't included, and short positions are never reported on 13F.
Follow a fund to get an alert (in-app, push or email digest, per your settings) when it files a new 13F, or when a new SC 13D (a 5%+ stake, filed within 10 days) by that fund shows up on SEC EDGAR.
