(Portfolio beta and CAPM)
You are putting together a portfolio made up of four different stocks. However, you are considering two possible weightings:
Portfolio Weightings | |||||||||
Asset | Beta | First Portfolio | Second Portfolio | ||||||
A | 2.40 | 20% | 30% | ||||||
B | 0.90 | 20% | 30% | ||||||
C | 0.60 | 30% | 20% | ||||||
D | −1.80 | 30% | 20% |
a. What is the beta on each portfolio?
b. Which portfolio is riskier?
c. If the risk-free rate of interest were 3 percent and the market risk premium were 7.5 percent, what rate of return would you expect to earn from each of the portfolios?
a]
Beta of each portfolio = (weight of each asset * beta of each asset)
b]
Second portfolio is riskier as it has a higher beta
c]
required return = risk free rate + (beta * market risk premium)
