Just pay close attention to what the mutual fund invests in, as the so called goals of the fund may be different than what they're actually doing (ie: they advertise the fund as conservative, but actually invest in non-conservative investments).
I seem to recall last summer, there was a bond fund that never valued their holdings properly, and when a "real" valuation was done, the share value plunged 90% or so.
Never believe what you see and never be afraid to question anything as it relates to your own money.
