The beta endpoint regresses asset returns on the market and returns beta, alpha, correlation and R-squared; the capm endpoint returns the CAPM expected return (risk-free + beta x market risk premium) and Jensen's alpha; the treynor endpoint returns the Treynor ratio (reward per unit of systematic risk). This measures risk relative to a market, distinct from single-series total-risk tools — it needs two series. Computed locally, nothing stored. Works for stocks, funds, crypto, FX or portfolios.",
