Estimated $ traded · quarter-end prices (an exit at the prior quarter-end), no cost basis
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.
Top-heavy: focused book
