Tracked Funds Public SEC 13F filings

Funds

How famous funds change their portfolios over time. Every quarter each Tracked Fund files a Filed Book — its reported US equity holdings — and we show the Filing Changes against the quarter before: New Buys, Adds, Trims, Exits and Holds. Weights, ranks and reported value only; no trading signals, no affiliation, not investment advice.

What you are looking at

What a 13F is

Form 13F is a quarterly report that US institutional investment managers with at least $100 million in qualifying assets must file with the SEC. It lists the manager's holdings of US-listed equities (and certain options and convertibles) as of the quarter end.

The 45-day lag

A 13F is due up to 45 days after the quarter ends, so the newest Filed Book here is always six to twenty weeks old by the time you read it. Managers may also amend a filing later, or hold some names back under confidential treatment — we flag that where it happens.

Long US equities only

A 13F shows long positions in US-listed securities. It does not show short positions, cash, bonds, derivatives used for hedging, or non-US listings — so the weights here are shares of the reported book, not of the whole fund.

Where the data comes from

Straight from SEC EDGAR, parsed from the machine-readable information tables that began in 2013. Issuers are matched to tickers where possible; a Filing Change is classified on split-adjusted shares held, never on weight, which moves with price.

algo2alpha has no affiliation with any of these funds or their managers. Nothing on these pages is investment advice or a recommendation to buy or sell any security. Reported values are at fund scale in USD billions; share counts are never shown.
