Suppose the expected returns of stock J and K are 15% and 25% respectively and the standard deviation of stocks J and K are 0.1 and 0.2 respectively. If you were to create a portfolio consisting of 30% J and 70% K: Calculate the expected return and standard deviation when the correlation coefficient between the stocks is 0.4 (4 marks) Calculate the standard deviation when the correlation coefficient between the stocks is -0.4 (3 marks) Demonstrate by appropriate calculations whether or not diversification has been achieved (4 marks) Based on parts i) and ii) above how does the correlation coefficient affect the standard deviation of the portfolio (4 marks)
