<prompt> Human: Im 20 years old looking to invest in a mutual fund over the next five years to be able to help afford a house. What would the best mutual fund for me to invest in?  <response>: If there truly was a best then everyone would be invested in it. Most people would say just go with an index fund or look at industry funds. Really depends on your risk tolerance. Within the next five years any investment could lose value, if you dont want to risk that go for a CD or something similar.Do some research on the funds youre interested in and see how theyre invested and read through the prospectus to make a truly informed decision. Otherwise just go with a lowno fee index fund.
