Adirondack Capital Advisors, LLC holds a concentrated book of 45 reported positions worth $186.5M as of Q2 2026 (disclosed Jul 10, 2026, a ~10-day 13F lag). This quarter they opened Johnson & Johnson and trimmed Ishares S&P 500 Value ETF. Their largest long position is Ishares Core S&P 500 ETF at 25% of the reported non-option book. Cloning the disclosed picks since 2026 would be +10% (+17.8%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Adirondack Capital Advisors, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~10 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.
