Xtreme IT Berhad is considering two overseas locations for a planned expansion of its production facilities. The future returns from the investments depend to a large extent on the economic situation of the countries under consideration. An analysis of the expected rates of return under three different scenarios is as follows: Probability 0.3 Expected return of country A Expected return of country B 20% 10% 0.3 10% 20% 0.4 15% 20%. (a) Calculate the mean return and the standard deviation of the returns from the investment in each country. (b) Calculate the standard deviation of the portfolio if the available funds were split 30% to country A and 70% to country B? (Assume zero correlation between returns from the two countries) (c) Assess how does the riskiness of an asset been evaluated.
