Syntax Research, Inc. holds a focused book of 178 reported positions worth $136.9M as of Q2 2026 (disclosed Jul 31, 2026, a ~31-day 13F lag). This quarter Fedex Freight Holding Co first appears in 13F filings (one of 4 new listings in the book), a listing rather than a purchase; they opened Cme Group Inc and trimmed Ishares Core S&P 500 ETF. Their largest long position is Ishares Core S&P 500 ETF at 10% of the reported non-option book. Cloning the disclosed picks since 2024 would be +56% (+20.7%/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 8.7 points over this window.
Growth of $10,000 cloning Syntax Research, Inc.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~31 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
