Suppose that the standard deviation of returns from a typical share is about 0.52 for 52% a year. The correlation between the returns of each par of shares is about 0.7. a. Calculate the variance and standard deviation of the returns on a portfolio that has equal investments in 2 shares, 3 shares, and so on, up to 10 shares. (Use decimal values, not percents. In your calculations. Do not round intermediate calculations. Round the "Variance" answers to 6 decimal places. Round the "Standard Devlation" answers to 3 decimal places.) No. of Shares 1 Variance Standard Deviation(%) 2 3 4 5 6 7 8 9 10 b. How large Is the underlying market varlance that cannot be diversified away? (Do not round Intermediate calculations. Round your answer to 3 decimal places.) Market risk c. Now assume that the correlation between each pair of stocks is zero. Calculate the variance and standard deviation of the returns on a portfolio that has equal Investments in 2 shares, 3 shares, and so on, up to 10 shares. (Use decimal values, not percents, In your calculations. Do not round intermediate calculations. Round the "Varlance" answers to 6 decimal places. Round the "Standard Deviation" answers to 3 decimal places.) No. of Shares 1 Variance Standard Deviation(%) 2 3 4 5 8 7 8 9 10
