A) Effectiveness.
That is the most important aspect to measure.
Answer:
C. Borrowing $43 at the risk-free rate and investing the total amount ($143) in the risky asset.
Explanation:
Outcome Return 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)
w1 = $143;
(1 - w1)$100 = $100 - $143
(1 - w1)$100 = -$43
