(Expected rate of return) Robert Gage is considering whether to invest in a newly formed investment fund. The fund’s investment objective is to acquire home mortgage securities at what it hopes will be bargain prices. The fund sponsor has suggested to Robert that the fund’s performance will hinge on how the national economy performs in the coming year. Specifically, he suggested the following possible outcomes:

State of the Economy

                                   Probability Fund Return

Rapid expansion

       and recovery.           5%             100%

Modest growth.              45%            35%

Continued recession.      45%             5%

Falls into depression.       5%             –100%
