Institutional 13F holdings & insider Form 4 filings
Every quarter, large investment managers must disclose their US stock holdings to the SEC on Form 13F, and company insiders must report their own trades on Form 4. These filings are public — but scattered across the SEC's EDGAR database and written for lawyers. Here we pull the latest ones straight from the source and lay them out plainly, so you can see what famous funds own and where insiders are putting their own money.
What is a 13F filing?
Any institutional manager overseeing at least $100 million in US equities must file Form 13F within 45 days of each quarter's end, listing the stocks they held on the last day of the quarter. Because of that 45-day lag, a 13F is a snapshot of the recent past, not a live portfolio — and it shows long US-listed positions only, not shorts, cash, or overseas holdings. Still, it's the clearest public window into how the world's best-known investors are actually positioned.
Dollar values are position market value as reported on the filing date. Weight is the position's share of the manager's disclosed 13F portfolio. Data source: SEC EDGAR.

What is a Form 4, and why watch cluster buys?
A Form 4 discloses a trade by a company insider — an officer, director, or 10%+ owner — and must be filed within two business days. Insiders sell for many reasons (taxes, diversification, a new house), so a single sale tells you little. Buying is different: an insider only buys when they expect the stock to rise. A cluster buy — several insiders of the same company buying in a short window — is the strongest version of that signal, because it's hard to explain away as one person's personal cash-flow need. It's not a guarantee, but it's a signal worth knowing about.

How to read these filings without getting fooled
A 13F is a rear-view mirror
Because managers have 45 days to file, a stock that shows up today may have been bought — or already sold — weeks ago. Treat 13Fs as a study of how great investors think and size positions, not as a list of trades to copy in real time.
Concentration tells a story
A manager with 90% of their portfolio in three names is expressing far more conviction than an index-like fund holding a thousand tiny positions. The weight column is often more revealing than the dollar amount.
Insider buying beats insider selling as a signal
Pay most attention to open-market purchases, especially clusters. Sales are noisy; purchases are deliberate. Cross-check a cluster buy against the company's fundamentals before drawing conclusions.
