ANSWER DOWN BELOW. FEEL FREE TO ASK ANY DOUBTS. THUMBS UP PLEASE.
a. AM = Simple Average of the returns.
AM of a= (0.20+0.10+0.14+0.05+0.01)/5 = 0.10
AM of b = (0.30+0.10+0.18+0.00-0.08)/5 = 0.10
b. stock B has a greater dispersion around the mean with its upper limit as 0.18 & lower limit as -0.08
c.
GM of A = [5√(1.20)*(1.10)*(1.14)*(1.05)*(1.01)]-1
= 9.80%
GM of B = [5√(1.30)*(1.10)*(1.18)*(1.00)*(0.92)]-1
= 9.20%
