This quarter they opened Bondbloxx BBG 20Y US Tsy ETF and trimmed Amazon.com Inc. Their largest long position is Nvidia Corp at 4% of the equity book. Cloning the disclosed picks since 2025 would be +14% (+16.0%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 3.2 points over this window.
Growth of $10,000 cloning Mattson Financial Services, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~35 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.
