Castlefield Investment Partners LLP holds a focused book of 35 reported positions worth $147.3M as of Q2 2026 (disclosed Aug 13, 2026, a ~44-day 13F lag). This quarter they opened Micron Technology Inc and trimmed Alphabet Inc-CL A. Their largest long position is Nvidia Corp at 8% of the reported non-option book. Cloning the disclosed picks since 2026 would be +1% (+1.0%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +3.6%, a 3.0-point gap that is the cost of the ~44-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Castlefield Investment Partners LLP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~44 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
