Answer:
a. 0.4840 percentage points
b. Project is overvalued
c. Required return from the portfolio would increase.
Explanation:
Note: The full question is attached as picture
New Allocation on Transfer Fuels corporation = 30%+35%
New Allocation on Transfer Fuels corporation = 65%
Beta after the new allocation = (20%*1.50) + (15%*1.10) + (65%*0.5)
Beta after the new allocation = 0.3 + 0.165 + 0.325
Beta after the new allocation = 0.79
New Required rate = Risk free rate + Beta* Market risk premium
New Required rate = 4%+ 0.79*5.5%
New Required rate = 4% + 4.345%
New Required rate = 8.345%
Hence, the change in required rate = 8.829% - 8.345% = 0.4840% . In this case, the project is overvalued if Brandon expects 6.85% . If Higher beta is chosen the portfolio risk would increase and required return from the portfolio would increase.
