Answer:
Portfolio return = 0.1089 or 10.89%
Step-by-step 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 + wB * rB + ... + wN * rN
Where,
- w is the weight of each stock in the portfolio
- r is the return of each stock
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 + 20000/246000 * 0.06 +
48000/246000 * 0.09 + 88000/246000 * 0.16
Portfolio return = 0.1089 or 10.89%
