a mutual fund is always going to charge a fee. if you just bought the same stocks, you’d already be ahead of a murual fund.
as to the mutual fund being smarter or beating the market, through trading or a sense of what’s coming, in general, they’re wrong. seems like ti would be better to just buy the same stocks as a fund you like and hold them. save the .3 or .5 % a year they charge to do the buying for you.
