RMR Capital Management, LLC holds a focused book of 76 reported positions worth $145.2M as of Q2 2026 (disclosed Jul 27, 2026, a ~27-day 13F lag). This quarter they opened Arthur J Gallagher & Co and trimmed Berkshire Hathaway Inc-CL B. Their largest long position is Berkshire Hathaway Inc-CL B at 17% of the reported non-option book. Cloning the disclosed picks since 2024 would be +24% (+10.7%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +38.6%, a 15.1-point gap that is the cost of the ~27-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning RMR Capital Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~27 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
