CAPM Problem Walk-Through PORTFOLIO REQUIRED RETURN Suppose you are the money manager of a $3.79 million investment fund. The fund consists of four stocks with the following investments and betas:
If the market's required rate of return is 9% and the risk-free
rate is 5%, what is the fund's required rate of return? Do not
round intermediate calculations. Round your answer to two decimal
places. |
First we will calculate the weights of each stock in the portfolio. This is done to calculate the weighted average beta of the portfolio.
Weight of each stock = Stock's value / Total portfolio value
Total portfolio value = $3.79 million or $3790000
Stock A's weight = $200000 / $3790000 = 0.05277
Stock B's weight = $560000 / $3790000 = 0.14775
Stock C's weight = $1180000 / $3790000 = 0.31134
Stock D's weight = $1850000 / $3079000 = 0.488126
In the next step, we will multiply the weights calculated above with the respective betas of stocks as per below:
Stock A = 0.05277 * 1.5 = 0.079155
Stock B = 0.14775 * (-0.5) = - 0.073878
Stock C = 0.31134 * 1.25 = 0.389182
Stock D = 0.488126 * 0.75 = 0.36609
In the next step, we will calculate the portfolio beta by adding the weighted average beta calculated in the above step:
Portfolio beta = 0.079155 + (-0.073878) + 0.389182 + 0.36609
Portfolio beta = 0.76
Now, we will use the CAPM equation to find the expected or required rate of return of the fund. As per CAPM equation,
Required rate of return = Risk free rate + Beta * ( Market rate - Risk free rate)
Given: Risk free rate = 5%, Market rate = 9%, Beta of the portfolio = 0.76
Now, putting these values in the above equation ,we get,
Required rate of return = 5% + 0.76 * (9% - 5%)
Required rate of return = 5% + (0.76 * 4%)
Required rate of return = 5% + 3.04%
Required rate of return = 8.04%
