This quarter they opened Applied Materials Inc and trimmed Dimensional Emrg MRKT Core. Their largest long position is Dimensional US Eq MKT ETF at 29% of the equity book.

Growth of $10,000 cloning Flagstone Financial Management's disclosed long 13F book, rebalanced on each filing date (so it reflects the ~45-day reporting lag, 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.
