The Security Market Line (SML) provides the relationship between risk and required rate of return. Which of the following statements about the SML is most correct?
A | The relevant risk is portfolio risk, which is measured by beta. |
B | The relevant risk is total risk, which is measured by standard deviation. |
C | The relevant risk is mutual risk, which is measured by coefficient of variation. |
D | The SML is an equation, but it cannot be graphed. |
E | The SML is a graphed line, but it cannot be expressed as an equation. |
Correct option is A - Relevant risk is portfolio risk, which is given by beta.
When plotting the SML, the y-axis represents the expected return and the x-axis represents the risk, i.e., beta.
SML equation is the same as CAPM method which involves beta -
Expected return (ERi) = Risk free rate (Rf) + Beta x [ Expected return of market (ERm) - Risk free rate (Rf) ]
