Run an OLS regression: . β captures how strongly the stock moves with the market. R² tells you what fraction of variance is systematic.
The Capital Asset Pricing Model says a stock's expected return depends only on its sensitivity to the market (beta). Take the risk-free rate, then add a premium proportional to how much the stock co-moves with the broad index. Investors only get paid for systematic risk, because everything else can be diversified away.
