Expert Solution

Answer to Question 1:

Answer a.

Expected Return = 0.30 * (-0.06) + 0.50 * 0.06 + 0.20 * 0.12
Expected Return = 0.036 or 3.60%

Answer b.

Variance = 0.30 * (-0.06 - 0.036)^2 + 0.50 * (0.06 - 0.036)^2 + 0.020 * (0.12 - 0.036)^2
Variance = 0.003194

Standard Deviation = (0.003194)^(1/2)
Standard Deviation = 0.0565 or 5.65%

Answer to Question 2:

Answer a.

Excess Return = Return for Stock A - Return for T-bills
Excess Return = 18% - 4%
Excess Return = 14%

Answer b.

Average Return for Stock A = [0.18 + 0.08 + 0.19] / 3
Average Return for Stock A = 0.45 / 3
Average Return for Stock A = 0.15 or 15%

Answer c.

Average Return for T-bills = [0.04 + 0.05 + 0.02] / 3
Average Return for T-bills = 0.11 / 3
Average Return for T-bills = 0.0367 or 3.67%

Answer d.

Average Excess Return = Average Return for Stock A - Average Return for T-bills
Average Excess Return = 15.00% - 3.67%
Average Excess Return = 11.33%
