Parthenon LLC holds a focused book of 133 reported positions worth $962.0M as of Q2 2026 (disclosed Jul 23, 2026, a ~23-day 13F lag). This quarter they opened Ishares National Muni Bond E and trimmed Microsoft Corp. Their largest long position is Microsoft Corp at 9% of the reported non-option book. Cloning the disclosed picks since 2024 would be +29% (+14.6%/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 5.8 points over this window.
Growth of $10,000 cloning Parthenon LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~23 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
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
