Mainstay Capital Management LLC holds a focused book of 144 stocks worth $1.4B as of Q2 2026 (disclosed Aug 12, 2026, a ~43-day 13F lag). This quarter they opened Harbor Commodity All Weather and trimmed Freedom 100 Emeging MRKT ETF. Their largest long position is Ishares Msci USA Value Facto at 9% of the equity book. Cloning the disclosed picks since 2024 would be +30% (+15.5%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +33.4%, a 3.8-point gap that is the cost of the ~43-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Mainstay Capital Management LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~43 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
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
