Samjo Management, LLC holds a focused book of 58 reported positions worth $293.0M as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter Digimarc Corp first appears in 13F filings, a listing rather than a purchase; they opened Fluor Corp and trimmed PDF Solutions Inc. Their largest long position is PDF Solutions Inc at 13% of the reported non-option book. Cloning the disclosed picks since 2025 would be +20% (+25.2%/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 4.0 points over this window.
Growth of $10,000 cloning Samjo 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.
