|
18%
|
- 0.3
|
|
Share KAY
|
24%

a) Calculate the covariance between Share JAY and KAY returns.
b) What is the expected return and standard deviation of returns on a portfolio comprising 35% in Share JAY and 65% in Share KAY?
c) If you wanted to create a portfolio consisting only of these two shares, how much would you need to invest (weights) in each share so that your portfolio return would be equal to 15.6%? Note: do not round.
d) Using the weights calculated in part c), calculate the variance and standard deviation of your portfolio.
