This paper provides an explanation for the diversity in investment str
ategies and fees of open-end mutual funds. Mutual funds seek to dissua
de redemptions through front- and back-end load fees. The empirical ev
idence is consistent with model predictions that such fees dissuade re
demptions in open-end funds, and that funds hold more cash when there
is uncertainty about redemptions. Furthermore, funds with load and red
emption fees hold less cash that their no-load counterparts. The resul
ts suggest that aggressive funds are sensitive to cash flows and are l
ikely to rely on fees to dissuade redemptions.
