An asset has an average historical rate of return of 12.1 percent and a variance of 0.01089091. What is the upper percentage range of returns would you expect to see approximately two-thirds of the time? (Round your answer to 2 decimal places. Omit the "%" sign in your response.)
Solution: | ||||
The upper percentage range of returns = 22.54 | ||||
Working Notes: | ||||
two third of times means 2/3 = 0.666666 or 68 % of times | ||||
Range of returns are calculated in 68% , 95% , 99 % | ||||
Our case is of 68% or two third of times | ||||
At 68% of confidence level range of return would be given by Avg. of returns ± 1 times multiple of standard deviation of the returns | ||||
Variance = (Standard deviation )^2 | ||||
Standard deviation = (Variance)^(1/2) | =(0.01089091)^(1/2) | |||
=0.104359523 | ||||
R = µ ± 1 (s.d.) | ||||
R= Expected range of returns | ||||
µ = mean of returns or Avg. Of returns = 12.10%=0.121 | ||||
s.d. = Standard deviation of the bond returns = 0.104359523 | ||||
R = µ ± 1 (s.d.) | ||||
low | =0.121 - 0.104359523 = 0.0166404 = 1.66404 % | |||
High | =0.121 + 0.104359523 =0.225359523 = 22.5359523 = 22.54 % | |||
R= Expected range of returns = 1.66% to 22.54% | ||||
As question requirement is high range = 22.54 | ||||
