Answer:
12.58%
Explanation:
The expected retained of a portfolio refers to the addition of the multiplication of the of weight of each asset and the expected return of each asset of each asset in the portfolio.
Since the weight of Stocks X, Y and Z are 16%, 31% and 53% respectively, and their expected values are 9%, 12% and 14% respectively, the expected return of the portfolio in this question can therefore be estimated as follows:
Portfolio expected return = (16% × 9%) + (31% × 12%) + (53% × 14%)
= 1.44% + 3.72% + 7.42%
Portfolio expected return = 12.58%
Therefore, the expected return on the portfolio is 12.58%.
