Answer:
Expected return of the portfolio = 8.57%
Step-by-step explanation:
The expected return of the portfolio is the weighted average return of all assets in that portfolio, which is calculated as below:
The expected return of the portfolio = (Weight of U.S. government T-bills x Return of U.S. government T-bills) + (Weight of large-company stocks x Return of large-company stocks) + (Weight of small-company stocks x Return of small-company stocks)
= 47% x 4.08% + 38% x 11.38% + 15% x 15.53% = 8.57%
