What a 13F does and doesn’t reveal
A 13F captures only Pat Dorsey — Dorsey Asset Management’s long positions in US-listed stocks at a single quarter-end, so it is best read as a lagged snapshot rather than a live portfolio.

The signal is in the pattern over time: which names Pat Dorsey — Dorsey Asset Management is building up, trimming, or exiting, and how concentrated the book stays from quarter to quarter.
Frequently asked questions
What is an SEC 13F filing?
A Form 13F is a report that every institutional investment manager with at least $100 million in US-listed securities must file with the SEC within 45 days of each quarter's end. It lists the manager's long positions in US-listed stocks and certain options, with the share count and market value of each. Pat Dorsey — Dorsey Asset Management's profile on this page is built directly from those filings.
How current is the 13F data on Pat Dorsey — Dorsey Asset Management's page?
It reflects Pat Dorsey — Dorsey Asset Management's most recently filed 13F, currently the quarter ending Q1 2026. Because managers have up to 45 days after a quarter closes to file, a 13F is always a slightly lagged view rather than a live portfolio. When Pat Dorsey — Dorsey Asset Management files its next quarterly report, this page refreshes automatically.
Can I see Pat Dorsey — Dorsey Asset Management's complete list of holdings?
This page highlights Pat Dorsey — Dorsey Asset Management's largest positions rather than all 11 names in the filing. The complete, position-by-position 13F is public and available from the SEC's EDGAR database under Pat Dorsey — Dorsey Asset Management's filings.
Does a 13F show everything Pat Dorsey — Dorsey Asset Management owns?
No. A 13F only covers long positions in US-listed stocks and certain options. It leaves out short positions, cash, bonds, commodities, foreign-listed stocks, and private holdings, so it is a partial view of Pat Dorsey — Dorsey Asset Management's book rather than its full strategy or total assets.
Is 13F data investment advice?
No. Everything here is educational. 13F positions are disclosed with a delay, cover only long US-listed holdings, and never explain why Pat Dorsey — Dorsey Asset Management made a trade or at what price. Treat it as a research lens, not a recommendation, and speak with a licensed financial advisor before making investment decisions.
Not investment advice. Holdings data comes from public SEC Form 13F filings, which are filed with a delay of up to 45 days and may be amended later. It describes historical, disclosed positions in US-listed securities only, meaning no shorts, cash, or foreign holdings, and it is not a recommendation. Always do your own research and speak with a licensed financial advisor before making investment decisions.
