Banque de Luxembourg S.A. holds a focused book of 78 reported positions worth $212.0M as of Q2 2026 (disclosed Jul 9, 2026, a ~9-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Applied Materials Inc and trimmed Alphabet Inc-CL A. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 14% of the reported non-option book. Cloning the disclosed picks since 2025 would be +13% (+7.9%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +16.5%, a 3.8-point gap that is the cost of the ~9-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Banque de Luxembourg S.A.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~9 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
