Explanation / Answer

Answer 19 ) Expected return of equally weighted portfolio = Weight of stock A x Return of stock A + Weight of stock B x Return of stock B + Weight of stock C x Return of stock C

Expected Return = 1/3 * 0.19 + 1/3 *0.15 + 1/3 *0.09 = 14.33%

Answer Option c)

Answer b)

Variance of portfolio = (Weight of A * St.deviation of A )^2 +(Weight of Market * St. deviation of Market)^2 + (2* Weight of A*Weight of Market *Covariance Market &A)

St. deviation = (Variance)^1/2

St. deviation A = (0.0200)^1/2 = 0.141421

St. deviation Market = (0.0064)^1/2 = 0.080

Putting all the value in the above formulae = (0.005) + (0.0016) + 0.0035 = 0.0101

Variance = (0.005) + (0.0016) + (0.0035) = 0.0101

Answer-Option b)

Answer C) Beta Of C = Covariance of C with market / Variance of Market = 0.0013 / 0.0064 =0.203

Answer -Option c)
