Suppose you are the money manager of a $3.92 million investment fund. The fund consists of four stocks with the following investments and betas:
Stock | Investment | Beta |
A | $ 200,000 | 1.50 |
B | 620,000 | (0.50) |
C | 900,000 | 1.25 |
D | 2,200,000 | 0.75 |
If the market's required rate of return is 9% and the risk-free rate is 4%, what is the fund's required rate of return? Do not round intermediate calculations. Round your answer to two decimal places.
Let’s first calculate the portfolio beta on the basis of investments in each stock
Total Portfolio investment = Investment in stock A + Investment in stock B + Investment in stock C + Investment in stock D
= $200,000 + $620,000 + $900,000 + $2,200,000 = $3,920,000 or 3.92 million
Portfolio beta = ∑ (stock’s investment amount/ Portfolio value) * beta of stock
= ($200,000/ $3,920,000) * 1.50 + ($620,000/ $3,920,000) * (-0.50) + ($900,000/ $3,920,000) * 1.25
+ ($2,200,000/ $3,920,000) * 0.75
= 0.7054
Therefore beta of portfolio is 0.7054
Now by using with securities market line (SML), we can calculate required rate of return of portfolio in following manner
Required rate of return of portfolio = risk free rate (rf) + β of portfolio *[Expected market return (Rm) – risk free rate (rf)]
Where,
Required rate of return of portfolio =?
Risk free rate (rf) = 4%
Beta of portfolio β = 0.7054
The expected return on the market Rm = 9%
Now putting all the values into formula, we get
Required rate of return of portfolio = 4% + 0.7054 * (9% - 4%)
= 4% + 0.7054 * 5%
= 7.53%
Therefore the fund's required rate of return is 7.53%
