Capstone Capital LLC holds a concentrated book of 26 reported positions worth $175.1M as of Q2 2026 (disclosed Jul 22, 2026, a ~22-day 13F lag). This quarter they opened Lam Research Corp and trimmed Dimensional Emrg MRKT Core. Their largest long position is Dimensional US Core Equity 2 at 47% of the reported non-option book. Cloning the disclosed picks since 2024 would be +29% (+15.3%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Capstone Capital LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~22 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.
