Foundational theory
Discussion of quantitative methods draws on established literature — portfolio theory and the Sharpe ratio (Sharpe, 1966), the Kelly criterion (Kelly, 1956), option pricing (Black & Scholes, 1973; Merton, 1973), and standard references on backtesting, market microstructure and trading-system design. Where we simplify, we say so. See our methodology.
