" I’m going to use my good old suitcase metaphor one more time: A mutual fund is like a suitcase that holds dozens—and often hundreds—of individual stocks. If you like what is packed inside the suitcase, then you simply purchase shares of that mutual fund and, voilà, you are the proud owner of a small fraction of each one of the holdings in that suitcase. This gives you instant diversification, even though you bought just one mutual fund. "
