Work out beta of a stock instantly with clear inputs, formula shown and shareable results.
Beta is the correlation with the market scaled by the ratio of volatilities, measuring how much a stock moves for a given market move. R-squared then shows how much of its total risk is market-driven and how much is diversifiable stock-specific risk.
Beta
β = ρ × σ_stock / σ_market; R² = ρ²
Figures are estimates for planning only. Market returns are not guaranteed, and rates, limits and tax rules change. This is not financial or tax advice — speak to a qualified adviser before acting.
The stock amplifies market moves — a beta of 1.2 implies roughly a 12% move for a 10% market move.
Not very. It shifts with leverage, business mix and the estimation window, so treat any single figure as approximate.
