Answer:
a) Expected return is 15% and volatility is 25%
b) No. The portfolio is dominated equally 50 - 50.
c) Yes. It is not dominated.
Explanation:
a) An image showing the step by step solution is attached.
The table in the image is use to solve b and c.
b) No. The portfolio is dominated equally from the table.
c) Yes. It is not dominated.
To get the optimal portfolio we shall compute the proportion of weights that will be invested the Ford Motor and Molson Coors.
Proportion of weight of Ford Motor = (Variance of Molson Coors - Covariance of Ford Motor and Molson Coors) / (Variance of Molson Coors+Variance of Ford Motor - 2 covariance of Ford Motor and Molson Coors)
Proportion of weight of Ford Motor = (0.30^2 - 0)/( 0.30^2 + 0.40^2 -0)
= 0.09/0.25
= 0.36
Therefore, the weight of Molson Coors is:
= 1 - 0.36 = 0.64
An optimal efficient portfolio will consist of 36% of Ford Motor and 64% Molson Coors.
