Thayer Partners, LLC / MA holds a focused book of 100 reported positions worth $241.6M as of Q2 2026 (disclosed Jul 31, 2026, a ~31-day 13F lag). This quarter they opened JPM Nasdaq Equity Premium and trimmed Vanguard Ftse Developed ETF. Their largest long position is Vanguard S&P 500 ETF at 18% of the reported non-option book. Cloning the disclosed picks since 2026 would be +7% (+10.8%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Thayer Partners, LLC / MA's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~31 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.
