A stock has a beta of 1.4, an expected return of 17.2 percent, and lies on the security market line. A risk-free asset is yielding 3.2 percent. You want to create a portfolio that is comprised of the stock and the risk free and will have a portfolio beta of 0.8. What is the expected return on this portfolio?
a) 12.33% b) 13.87% c) 11.20% d) 14.41%
c) 11.20%
Step-1:Calculation of weight of both investment | ||||||||
Risk free asset as its name suggest has zero risk and hence has beta of 0. | ||||||||
Suppose, weight of risk free asset is "w" and so weight of stock is "1-w" | ||||||||
So, as per question, | ||||||||
Beta of portfolio | = | Sum of weighted beta of portfolio | ||||||
0.8 | = | (w*0)+((1-w)*1.4) | ||||||
0.8 | = | 0+((1.4-1.4w) | ||||||
0.8 | = | 1.4-1.4w | ||||||
1.4w | = | 0.6 | ||||||
w (Risk free asset) | = | 0.4286 | ||||||
1-w (Stock) | = | 0.5714 | ||||||
Step-2:Calculation of portfolio return | ||||||||
Weight | Return | |||||||
a | b | a*b | ||||||
Stock | 0.5714 | 17.20% | 9.83% | |||||
Risk free asset | 0.4286 | 3.20% | 1.37% | |||||
Portfolio return | 11.20% | |||||||
