11. DETERMINANTS OF CAPM
The sensitivity of a security to the movement of
the market is measured by “Beta Coefficient(
)”
Beta > 1.00 = aggressive security
Beta < 1.00 = defensive security
Beta of a portfolio is nothing but the weighted
average of the beta’s of securities that constitute
the portfolio, the weights being the proportion of
investments in the respective securities.
