make sure they are all answered and they are correct please
1) Variance of A = Standard Deviation 2 = 212 = 441
2) Variance of B = Standard Deviation 2 = 172 = 289
3) Variance of C = Standard Deviation 2 = 122 = 144
4) Variance of D = Standard Deviation 2 = 222 = 484
5) Correlation (A,A) = Co-variance (A,A) / (SD(A) * SD(A)) = Variance of A / (SD(A) * SD(A)) = 441/(21*21) = 1
6) Correlation (B,B) = Co-variance (B,B) / (SD(B) * SD(B)) = Variance of B / (SD(B) * SD(B)) = 289/(17*17) = 1
7) Correlation (C,C) = Co-variance (C,C) / (SD(C) * SD(C)) = Variance of C / (SD(C) * SD(C)) = 144/(12*12) = 1
8) Correlation (D,D) = Co-variance (D,D) / (SD(D) * SD(D)) = Variance of D / (SD(D) * SD(D)) = 484/(22*22) = 1
9) Co-variance(A,A) = Variance of A = 441
10) Co-variance (A,B) = Correlation(A,B) * SD(A) * SD(B) = 0.7000 * 21 * 17 = 249.90
11) Co-variance (A,C) = Correlation(A,C) * SD(A) * SD(C) = 0.4900 * 21 * 12 = 123.48
12) Co-variance (A,D) = Correlation(A,D) * SD(A) * SD(D) = 0.2500 * 21 * 22 = 115.50
13) Co-variance (B,A) = Co-variance (A,B) = 249.90
14) Co-variance (B,B) = Variance (B) = 289
15) Co-variance (B,C) = Correlation(B,C) * SD(B) * SD(C) = 0.4400 * 17 * 12 = 89.76
16) Co-variance (B,D) = Correlation(B,D) * SD(B) * SD(D) = 0.9600 * 17 * 22 = 359.04
17) Co-variance (C,A) = Co-variance (A,C) =123.48
18) Co-variance (C,B) = Co-variance (B,C) = 89.76
19) Co-variance (C,C) = Variance (C) = 144
20) Co-variance (C,D) = Correlation(C,D) * SD(C) * SD(D) = 0.2000 * 12 * 22 = 52.80
21) Co-variance (D,A) = Co-variance (A,D) =115.50
22) Co-variance (D,B) = Co-variance (B,D) =359.04
23) Co-variance (D,C) = Co-variance (C,D) =52.80
24) Co-variance (D,D) = Variance (D) = 484
25) Expected Return of portfolio = sum (Expected return (Stock) * Weight(Stock))
= (21 * 0.15) + (5 * 0.28) + (7 * 0.11) + (22 * 0.46) = 15.44%
26) Variance of Portfolio = [SD(A) * W(A)]2 + [SD(B) * W(B)]2 + [SD(C) * W(C)]2 + [SD(D) * W(D)]2 + [2* W(A) * W(B) * SD(A) * SD(B) * Cor (A,B)] + [2* W(B) * W(C) * SD(B) * SD(C) * Cor (B,C)] + [2* W(C) * W(D) * SD(C) * SD(D) * Cor (C,D)] + [2* W(A) * W(D) * SD(A) * SD(D) * Cor (A,D)] + [2* W(A) * W(C) * SD(A) * SD(C) * Cor (A,C)] + [2* W(B) * W(D) * SD(B) * SD(D) * Cor (B,D)]
= (21% * 0.15)2 + (17% * 0.28)2 + (12% * 0.11)2 + (22% * 0.46)2 + [2* 0.15 * 0.28 * 21% * 17% * 0.7] + [2* 0.28 * 0.11 * 17% * 12% * 0.44] + [2* 0.11 * 0.46 * 12% * 22% * 0.2] + [2* 0.15* 0.46 * 21% * 22% * 0.25] + [ 2* 0.15 * 0.11* 21% * 12% * 0.49] + [2* 0.28 * 0.46 * 17% * 22% * 0.96]
= 9.92 + 22.66 + 1.74 + 102.41 + 20.99 + 5.53 + 5.34 + 15.94 + 4.07 + 92.49
= 281.09
27) Standard Deviation on portfolio = root of 281.09 = 16.77%
