You want to create a portfolio equally as risky as the market, and you have $1,000,000 to invest. Consider the following information: |
Asset | Investment | Beta |
Stock A | $200,000 | 0.85 |
Stock B | $350,000 | 1.20 |
Stock C | 1.55 | |
Risk-free asset | ||
Required: |
(a) | What is the investment in Stock C? (Do not round your intermediate calculations.) |
(Click to select)$275,097$253,935$264,516$251,290$144,849 |
(b) | What is the investment in risk-free asset? (Do not round your intermediate calculations.) |
(Click to select)$192,903$178,065$305,151$176,210$185,484 |
And beta of risk free asset is assumed as zero.
We can use following formula to calculate the proportion of investment in stock C and risk free asset
Beta of portfolio = Beta of Stock A * weight of stock A in portfolio + Beta of Stock B * weight of stock B in portfolio + Beta of Stock C * weight of stock C in portfolio + Beta of risk free asset * weight of risk free asset in portfolio
Where,
Beta of portfolio = 1
Beta of Stock A = .85
Weight of stock A in portfolio = Investment in stock A / total investment in portfolio
= $200,000/$1,000,000 = 0.20
Beta of Stock B = 1.20
Weight of stock B in portfolio = Investment in stock B / total investment in portfolio
= $350,000/$1,000,000 = 0.35
Beta of Stock C = 1.55
Assume that investment in stock C is X, therefore
Weight of stock C in portfolio = X/ $1,000,000
Beta of risk free asset = 0
Weight of risk free asset in portfolio = ($1,000,000 - $200,000 - $350,000 –X)/$1,000,000
= ($450,000 –X) /$1,000,000
Now putting all the values into formula, we get
1 = 0.85 * 0.20 + 1.20 * 0.350 + 1.55 * (X/$1,000,000) + 0 * ($450,000 –X) /$1,000,000
Or 1 – 0.59 = 1.55 * (X/$1,000,000)
Or 0.41/1.55 = X/$1,000,000
Or X = 0.264516* $1,000,000 = $264,516
Therefore investment in stock C is $264,516
