You expect a tax-free municipal bond portfolio to provide a rate
of return of 4%. Management fees of the fund are .6%. What
fraction of portfolio income is given up to fees? If the
management fees for an equity fund also are .6%, but you expect
a portfolio return of 12%, what fraction of portfolio income is
given up to fees? Why might management fees be a bigger factor
in your investment decision for bond funds than for stock funds?
Can your conclusion help explain why unmanaged unit
investment trusts tend to focus
on the fixed-income market?
