Bornite Capital Management LP holds a focused book of 20 reported positions worth $794.6M as of Q2 2026 (disclosed Aug 13, 2026, a ~44-day 13F lag). This quarter Sinda Ltd first appears in 13F filings, a listing rather than a purchase; they opened Amazon.com Inc and trimmed Talen Energy Corp. Their largest long position is Talen Energy Corp at 8% of the reported non-option book. Cloning the disclosed picks since 2021 would be +147% (+19.5%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +201.0%, a 54.4-point gap that is the cost of the ~44-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Bornite Capital Management LP'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.
