(Computing the standard deviation for an individual investment) James Fromholtz 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.

a. Based on these potential outcomes, what is your estimate of the expected rate of return from this investment opportunity?

b. Calculate the standard deviation in the anticipated returns found in part a.

c. Would you be interested in making such an investment Note that you lose all your money in one year if the economy collapses into the worst state or you double your money if the economy enters into a rapid expansion.

A. Yes, I would be interested in making such an investment. The economy is most likely to begin a rapid expansion and recovery.

B. Your interest in making such an investment would depend on your risk tolerance. If you do not like risk you should avoid this investment, however if you do not mind risk you may want to make this investment.
