Chọn đáp án E
Giải thích: 9% = w1(12%) + (1 - w1)(5%)
9% = 12%w1 + 5% - 5%w1
4% = 7%w1
w1 = 0.57
1 - w1 = 0.43
0.57(12%) + 0.43(5%) = 8.99%.
Investing \$100 in the risky asset.
Investing \$43 in the risky asset and \$57 in the riskless asset.
Investing \$80 in the risky asset and \$20 in the risk-free asset.
such a portfolio cannot be formed.
Borrowing \$43 at the risk-free rate and investing the total amount (\$143) in the risky asset
Chọn đáp án E
Giải thích: For \$100: (115 - 100)/100 = 15%
0.15 = w1(0.12) + (1 - w1)(0.05)
0.15 = 0.12w1 + 0.05 - 0.05w1
0.10 = 0.07w1
w1 = 1.43(\$100) = \$143 so (1 - w1)\$100 = -\$43.

Chọn đáp án A
Giải thích: For \$100: (114 - 100)/100 = 14%
0.14 = w1(0.11) + (1 - w1)(0.045)
0.14 = 0.11w1 + 0.045 - 0.045w1
0.095 = 0.065w1
w1 = 1.46(\$100) = \$146 (1 - w1)\$100 = -\$46.
