Millburn Ridgefield LLC holds a focused book of 39 reported positions worth $4.6B as of Q1 2026 (disclosed Apr 22, 2026, a ~22-day 13F lag). This quarter they trimmed Ishares Msci Taiwan ETF. Their largest long position is Ishares Russell 1000 ETF at 13% of the reported non-option book. Cloning the disclosed picks since 2017 would be +151% (+10.1%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +169.5%, a 18.0-point gap that is the cost of the ~22-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Millburn Ridgefield LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~22 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
