What the book is made of

Performance follows portfolio shape as much as skill: a Scottish, long duration book does a different job from an English one hour book, so the mix belongs beside the money, not in a footnote.

Attribution. A unit belongs to whoever the market registers as its seller today, so a book that changed hands mid year credits the whole year to the current seller. We have recorded optimiser switches since 27 August 2026 and the record deepens from here. Corporate families are not joined: a platform selling through several registered entities appears as several rows on the optimiser list.
