A) the variance of a stock's returns compared to variance of the market's returns
B) systematic and unsystematic risks
C) market and firm-specific risks
D) an asset's expected return and the risk-free rate
The risk of a portfolio is the variance of its return. However, the variance of the returns of an individual asset is not an appropriate measure of its risk. Discuss
