Chapter 5, Problem 16PS

For Problems 12-16, assume that you manage a risky portfolio with an expected rate of return of 17% and a standard deviation of 27%. The T-bill rate is 7%.
16. Your client (see previous problem) wonders whether to switch the 70% that is invested in your fund to the index portfolio. (LO 5−4)
a. Explain to your client the disadvantage of the switch.
b. Show your client the maximum fee you could character (as a percent of the investment in your fund. deducted a the end of the year) that would still leave him at least as well off investing in your fund as in the passive one. (Hint: The fee will lower the slope of your client’s CAL by reducing the expected return net of the fee.)
