An investment has the following range of outcomes and probabilities:
Outcomes Probability of Outcomes
6% 0.20
9% 0.60
12% 0.20
Calculate the expected value and the standard deviation (round to two places after the decimal point where necessary).
5. If the two investments above were perfectly positively correlated (rij= +1), what would be the portfolio standard deviation?
11. If another security had a lower beta than indicated in problem 10, would Ki be lower or higher? What is the logic behind your answer in terms of risk?
