Rubicon Advisors, GP holds a focused book of 86 reported positions worth $137.3M as of Q2 2026 (disclosed Jul 29, 2026, a ~29-day 13F lag). This quarter Space Exploration Techn-CL A first appears in 13F filings, a listing rather than a purchase; they opened Fed Hermes Large Cap Growth and trimmed Apple Inc. Their largest long position is Apple Inc at 10% of the reported non-option book. Cloning the disclosed picks since 2026 would be +14% (+27.7%/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 10.3 points over this window.
Growth of $10,000 cloning Rubicon Advisors, GP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~29 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.
