Answer:
Portfolio return = 0.1004646154 or 10.04646154% rounded off to 10.05%
Option B is the correct answer
Explanation:
The expected return of a portfolio is the function of the weighted average of the individual stock returns that form up the portfolio. The formula to calculate the expected return of a two stock portfolio is as follows,
Portfolio return = wA * rA + wB * rB
Where,
As the investment in total portfolio is 97500 and the investment in stock A is 84650, the investment in stock B will be,
Stock B = 97500 - 84650 = 12850
Portfolio Return = 84650 / 97500 * 0.106 + 12850 / 97500 * 0.064
Portfolio return = 0.1004646154 or 10.04646154% rounded off to 10.05%
