Beta

    Beta Coefficient

    Risk & Portfolio

    Measures a stock's volatility relative to the broader market (Nifty 50). Indicates systematic risk.

    Formula

    Beta = Covariance(Stock, Market) / Variance(Market)

    Why it matters

    Beta >1 means more volatile than market (high risk, high reward). Beta <1 means less volatile. Defensive stocks typically have low beta.
