Assume the betas for securities A, B, and Care as shown here: B a. Calculate the change in return for each security if the market experiences increase in its rate of return of 12.1% over the next period. b. Calculate the change in retum for each security if the market experiences a decrease in its rate of return of 10.6% over the next period. c. Rank and discuss the relative risk of each security on the basis of your findings. Which security might perform best during an economic downturn? Explain. a. Calculate the change in return for each security if the market experiences increase in its rate of return of 12.1% over the next period. Security A's change in return will be%. (Round to two decimal places.) Security B's change in return will be %. (Round to two decimal places.) Security C's change in return will be%. (Round to two decimal places.) b. Calculate the change in retum for each security if the market experiences a decrease in its rate of return of 10.6% over the next period, Security A's change in return will be %. (Round to two decimal places.) Security B's change in return will be %. (Round to two decimal places.) Security C's change in retum will be%. (Round to two decimal places.) c. Rank and discuss the relative risk of each security on the basis of your findings. Which security might perform best during an economic downturn? Explain. (Selec the best choice below.) O A Security B is the least risky since its return is least responsive (regardless of direction) to changes in the market return. OB. Security A is the most risky. It has the highest relevant risk, as determined by the beta values and the greater changes security A's return for a given change in the market return. OC. Security C could be called defensive since it moves in the opposite direction from the market (ils return increased when the market return fell and vice versa). OD. During an economic downturn, it can probably be assumed that the market returri would decrease. If this occurred, security C would perform best. Otherwise, security B would be best since it would be least responsive to a change in the market return. O E. All the above statements are correct. Security A B Beta 1.44 0.77 -0.91
