Eos Management, L.P. holds a focused book of 35 reported positions worth $252.4M as of Q2 2026 (disclosed Jul 30, 2026, a ~30-day 13F lag). This quarter they opened Amphenol Corp-CL A and trimmed O'reilly Automotive Inc. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 33% of the reported non-option book. Cloning the disclosed picks since 2025 would be +15% (+9.4%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Eos Management, L.P.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~30 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.
