Suppose a stock had an initial price of $72 per share, paid a dividend of $1.20 per share during the year, and had an ending share price of $79.
Compute the percentage total return.
A stock had returns of 11 percent, 16 percent, 14 percent, 8 percent, 13 percent, and -1 percent over the last six years.

Using the following returns, calculate the arithmetic average returns, the variances, and the standard deviations for X and Y.
Explanation / Answer
Requirement 1
Arithmetic average return = X1 +X2 + . . . .Xn / n
a) Arithmetic average return for X = [ 10 + 28 + 17 + (-18) + 19 ]/ 5 = 11.20 %
ANSWER = C) 11.20 %
b) Arithmetic average return for Y = [ 23 + 44 + (-11) + (-25) + 52 ]/ 5 = 16.60 %
ANSWER = A) 16.60%
Requirement 2
Variance = [ (X1 - x)2 + (x2 - x)2 + . . . .. (Xn - x)/ (n-1)]
a) Variance X = [( 10 - 11.20)2 + (28 - 11.20)2 + (17- 11.20)2 + (-18 - 11.20)2 + (19 - 11.20)2] / (5 - 1)
= 1.44 + 282.24 + 33.64 + 852.64 + 60.84 / 4
= 307.70 or 0.0307700
ANSWER = A) 0.0307700
b) Variance Y = [(23 - 16.6)2 + (44 - 16.60) 2 + (-11 - 16.60)2 + (-25-16.60)2 + (52 - 16.60)2 ] / 4
= 1134.30 or 0.113430
ANSWER = D) 0.113430
Requirement 3
Standard deviation = (Variance)^1/2
a) Standard deviation for X = (307.70)^1/2 = 17.54 %
ANSWER = c) 17.54%
b) Standard deviation for Y = (1134.30)^1/2 = 33.68%
Initial price (P0)= $72 per share,
Dividend (d)= $1.20 per share
Ending share price (P1) = $79
percentage total return = (P1 + D - P0) / P0 * 100
= (79 + 1.2 - 72 )/ 72 * 100
= 11.39 %
stock had returns = 11 percent, 16 percent, 14 percent, 8 percent, 13 percent, and -1 percent over the last six years.
a) arithmetic return for the stock = X1 +X2 + . . . .Xn / n
= ( 11 + 16 + 14 + 8 + 13 + (-1) ) / 6
= 10.17 %
ANSWER =A) 10.17%
