Cobblestone Asset Management LLC holds a focused book of 74 stocks worth $239.8M as of Q2 2026 (disclosed Jul 21, 2026, a ~45-day 13F lag). This quarter they opened Schwab Intl Equity ETF and trimmed SS SPDR P S&P 500 Growth ETF. Their largest long position is JPMorgan Ultra-Short Income at 15% of the equity book. Cloning the disclosed picks since 2024 would be +18% (+9.9%/yr). That is a simulation of the disclosed long book, not audited returns.

The reported book (valued from quarter-end) returned +20.6%, a 2.2-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Cobblestone Asset Management LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects the ~45-day reporting lag, 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
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
