Q1) c) 2.13%
Explanation:
Geometric return= [(1+0.042) (1+0.097) (1-0.154) (1+0.125)]^1/4 - 1
= [(1.042) (1.097) (0.846) (1.125)]^0.25 - 1
= (1.0879)^0.25 - 1
= 1.0213 - 1
= 0.0213 or 2.13%
Q2) A) 4.95%
Explanation:
Total return= ending price - beginning price + dividend/ beginning price
= 36.12 - 35.37 + 1 / 35.37
= 1.75 / 35.37
= 4.95%
Q3) B) 6.65%
Explanation:
Expected return = probability × return
= 0.1 × -0.09 + 0.65 × 0.07 + 0.25 × 0.12
= -0.009 + 0.0455 + 0.03
= 0.0665 or 6.65%
Q4) D) 0.0343
Explanation:
Expected return = probability × return
= 0.4 × 5% + 0.6 × 12%
= 2% + 7.2%
= 9.2%
Standard deviation= √ probability (return - expected return)^2
= √ 0.4 (0.05 - 0.092)^2 + 0.6 (0.12 - 0.092)^2
= √ 0.4 (-0.042)^2 + 0.6 (0.028)^2
= √ 0.4 (0.001764) + 0.6 (0.000784)
= √ 0.0007056 + 0.0004704
= √ 0.001176
= 0.0343
