Lionstone Capital Management LLC holds a concentrated book of 11 reported positions worth $435.0M as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). Their largest long position is Api Group Corp at 24% of the reported non-option book. Cloning the disclosed picks since 2025 would be -1% (-1.2%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Lionstone Capital Management LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 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.
