Answer:
Portfolio r = 0.161379 or 16.1379% rounded off to 16.1%
Option a is the correct answer
Explanation:
The expected return of a portfolio is the function of the weighted average of the individual stocks' returns that form up the portfolio. To calculate the expected rate of return of a two stock portfolio, we use the following formula,
Portfolio r = wA * rA + wB * rB
Where,
Total investment in portfolio = 100 + 45 = 145
Portfolio r = 100/145 * 0.18 + 45/145 * 0.12
Portfolio r = 0.161379 or 16.1379% rounded off to 16.1%
