Pat Dorsey, Dorsey Asset Management, LLC (copied at disclosure) S&P 500

The reported book (valued from quarter-end) returned +431.5%, a 26.8-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.

Growth of $10,000 cloning Pat Dorsey, Dorsey Asset Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.

Use Arkolith to show Pat Dorsey's latest 13F book,
the biggest position changes this quarter, and the filing each one comes from.

Aggregated from SEC Form 13F filings (institutional reportable securities, disclosed quarterly, up to 45 days after quarter-end). Holdings are public domain, sourced to SEC EDGAR. The book totals, weighting, concentration and sectors cover reported non-option positions, which can include notes and warrants. Disclosed put/call options are listed separately and excluded from those figures. The performance line is a simulation of the disclosed long book, not an audited fund return. Every panel is one call to the Arkolith API & MCP server.
