Answer:
11.11%
Explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below for computing the rate of return
Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)
For Stock A
= 5% + 1.20 × (11% - 5%)
= 5% + 1.20 × 6%
= 5% + 7.2%
= 12.2%
For Stock B
= 5% + 0.5 × (11% - 5%)
= 5% + 0.5 × 6%
= 5% + 3%
= 8%
For Stock C
= 5% + 1.40 × (11% - 5%)
= 5% + 1.40 × 6%
= 5% + 8.4%
= 13.4%
For Stock D
= 5% + 0.75 × (11% - 5%)
= 5% + 0.75 × 6%
= 5% + 4.5%
= 9.5%
Now the rate of return would be
= (Stock A amount × expected return + Stock B amount × expected return + Stock C amount × expected return + Stock D amount × expected return) ÷ (Total amount)
= ($1,075,000 × 12.20% + $675,000 × 8% + $750,000 × 13.40% + $500,000 × 9.50%) ÷ ($3,000,000)
= ($131,150 + $54,000 + $100,500 + $47,500) ÷ ($3,000,000)
= 11.11%
