Marathon Capital Management holds a diversified book of 187 reported positions worth $493.9M as of Q2 2026 (disclosed Jul 22, 2026, a ~22-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Waystar Holding Corp and trimmed T Rowe Price Group Inc. Their largest long position is T Rowe Price Group Inc at 13% of the reported non-option book. Cloning the disclosed picks since 2024 would be +28% (+14.3%/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 4.3 points over this window.
Growth of $10,000 cloning Marathon Capital Management's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~22 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: diversified book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
