Stocks A and B have the following probability distributions: % Returns Probability A B 0.40 15 35 0.10 10 20 0.30 -5 15 0.20 -15 -5 If you form a 50-50 portfolio of the two stocks, calculate the expected rate of return and the standard deviation for the portfolio. (Remember, you must calculate a new range of outcomes for the portfolio.) Briefly explain why the standard deviation for the portfolio would be less than the weighted average of the standard deviations...
