Superinvestor real-time filings

Filings from the last 6 months in which a superinvestor is one of the filers. A superinvestor files a Form 4 within two business days of a trade when it owns more than 10% of a company or sits on its board, and a Schedule 13D or 13G when it owns more than 5%, so these filings are much more current than a quarterly 13F. Grouped by superinvestor, most recent first.

For company insiders buying stocks the superinvestors own, see Insider buys.

Each row adds up one type of transaction in one filing. All transaction types are shown, not only open-market purchases and sales. Filing counts leave out duplicate reports of the same trade.

Each 13D or 13G row is one filing. The stake is the largest one reported by any member of the filing group; the change is against the holder's previous filing on the same shares.
