Marietta Investment Partners LLC holds a diversified book of 170 reported positions worth $581.7M as of Q2 2026 (disclosed Aug 12, 2026, a ~43-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Silicon Motion Technol-ADR and trimmed Apple Inc. Their largest long position is Apple Inc at 7% of the reported non-option book. Cloning the disclosed picks since 2025 would be +17% (+20.9%/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 4.8 points over this window.
Growth of $10,000 cloning Marietta Investment Partners LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~43 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.
