Methodology
This review summarises the systematic book's daily mark-to-market profit and loss over the period under management. All cumulative figures and ratios are recomputed directly from the individual daily entries in the trading ledger to ensure internal consistency between the equity curve, the daily P&L series and the summary statistics.
The Sharpe ratio shown is calculated on the raw daily P&L series — mean divided by standard deviation, annualised by a factor of √252 — rather than on capital-adjusted returns, as no fixed capital base is allocated against the book. It should be read as an indicative, book-level risk-adjusted measure rather than a fund-level Sharpe ratio, and is based on a five-month sample; figures will be revisited as the track record lengthens. Figures are unaudited and subject to revision. Past performance is not indicative of future results.
