Please refer to the attached pictures. please read carefully all the problecgxms and double-check with the calculation.

Given Data

Average return = (-10% + 25% + 45%)/3 = 20% = 0.20

Var = ∑(Annual Return – Average Return)2 / N

Var = 0.155/3 = 0.051667 ~ 0.052

——————————————————–

1.2

SD = √Var = √0.051667 = 0.227

2.1

Given Data

Average return of A = (-0.05 + 0.10 + 0.16) / 3 = 0.07

Average return of B = (0.02 – 0.07 + 0.10) / 3 = 0.01666667

Calculation Table:

Cov(A,B) = ∑(Return A – Average Return A) (Return B – Average Return B) / N

Cov(A, B) = 0.0045 / 3 = 0.0015

——————————————————–

2.2

Calculation Table

Var(A) = ∑(Return A – Average Return A)2 / N

Var(A) = 0.0234 / 3 = 0.0078

SD(A) = √Var(A) = √0.0078 = 0.08832

——————————————————–

2.3

Calculation Table

Var(B) = ∑(Return B – Average Return B)2 / N

Var(B) = 0.01446667 / 3 = 0.0048222

SD(B) = √Var(B) = √0.0048222 = 0.0694

——————————————————–

2.4

Corr(A, B) = Cov (A, B) / (SD(A) SD(B))

Corr (A, B) = 0.24458
