The standard deviation of stock A is 25% p.a., the standard deviation of stock B is 38% p.a., and the standard deviation of stock C is 28% p.a. The correlations are as follows: Corr(A, B) = 0.4, Corr(A, C) = 0.6, and Corr(B, C) = 0.5. What is the variance of a portfolio in which you've invested 28% of your money in stock A, 31% in stock B, and the rest in stock C? Give the answer as a number with 4 decimals, e.g., 0.0076. Do not write any symbol. Reminder: Use the decimal expressions for the weights and standard deviations in your calculation.
