Rockingstone Advisors LLC holds a diversified book of 115 reported positions worth $249.1M as of Q2 2026 (disclosed Jul 14, 2026, a ~14-day 13F lag). This quarter they opened Navan Inc-CL A and trimmed Tower Semiconductor Ltd. Their largest long position is JPMorgan Ultra-Short Income at 5% of the reported non-option book. Cloning the disclosed picks since 2025 would be +13% (+14.0%/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 1.7 points over this window.
Growth of $10,000 cloning Rockingstone Advisors LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~14 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.
