Cooke & Bieler LP holds a diversified book of 103 reported positions worth $8.8B as of Q1 2026 (disclosed May 4, 2026, a ~34-day 13F lag). This quarter Sunbelt Rentals Holdings Inc first appears in 13F filings, a listing rather than a purchase; they opened Arthur J Gallagher & Co and trimmed Gildan Activewear Inc. Their largest long position is Gildan Activewear Inc at 4% of the reported non-option book. Cloning the disclosed picks since 2013 would be +230% (+9.7%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +248.6%, a 18.8-point gap that is the cost of the ~34-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Cooke & Bieler LP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~34 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.
