You want to create a portfolio equally as risky as the market, and you have $900,000 to invest. Consider the following information: |
Asset | Investment | Beta |
Stock A | $180,000 | 0.90 |
Stock B | $180,000 | 1.10 |
Stock C | 1.55 | |
Risk-free asset | ||
Required: |
(a) | What is the investment in Stock C? (Do not round your intermediate calculations.) |
(b) | What is the investment in risk-free asset? (Do not round your intermediate calculations.) |
Let investment in stock C=$x
Hence investment in risk-free asset=900,000-(180,000+180,000+x)=$540,000-x
Portfolio beta=Respective betas*Respective investment weights
1=(180,000/900,000*0.9)+(180,000/900,000*1.1)+(x/900,000*1.55)+(540,000-x/900,000)*0[Beta of risk free asset=0]
1=0.18+0.22+(x/900,000*1.55)
Hence x=(1-0.18-0.22)*900,000/1.55
=$348,387.10(Approx)=investment in Stock C
Hence investment in risk free asset=(540,000-348,387.10)=$191,612.90(Approx)
