A firm wishes to assess the impact of changes in the market return on an asset that has a beta of . a. If the market return increased by %, what impact would this change be expected to have on the asset's return? b. If the market return decreased by %, what impact would this change be expected to have on the asset's return? c. If the market return did not change, what impact, if any, would be expected on the asset's return? d. Would this asset be considered more or less risky than the market? a. If the market return increased by %, the impact on the asset's return is nothing%. (Round to one decimal place. Enter a negative percentage number if the asset return decreases.)

Stocks a, b, and c are similar in some respects: each has an expected return of 10% and a standard deviation of 25%. stocks a and b have returns that are independent of one another; i.e., their correlation coefficient, r, equals zero. stocks a and c have returns that are negatively correlated with one another; i.e., r is less than 0. portfolio ab is a portfolio with half of its money invested in stock a and half in stock b. portfolio ac is a portfolio with half of its money invested in stock a and half invested in stock c. which of the following statements is correct? a. portfolio ab has a standard deviation that is greater than 25%.b. portfolio ac has an expected return that is less than 10%.c. portfolio ac has a standard deviation that is less than 25%.d. portfolio ab has a standard deviation that is equal to 25%.e. portfolio ac has an expected return that is greater than 25%.
