Answer:
Portfolio return = 0.1089 or 10.89%
Explanation:
The expected return on a portfolio is the weighted average of the individual stocks' returns that form up the portfolio. To calculate the expected return on the portfolio we use the following formula,
Portfolio return = wA * rA Â + Â wB * rB Â + Â ... Â + Â wN * rN
Where,
To calculate the weight of each stock, we first need to calculate the investment in each stock and the total investment.
Stock A = 6000 * 15 = 90000
Stock B = 2000 * 10 = 20000
Stock C = 4000 * 12 = 48000
Stock D = 8000 * 11 = 88000
Total investment in portfolio = 90000+ 20000 + 48000 + 88000 = 246000
Portfolio return = 90000/246000 * 0.08 Â + Â 20000/246000 * 0.06 Â + Â
48000/246000 * 0.09 Â + Â 88000/246000 * 0.16
Portfolio return = 0.1089 or 10.89%
