Warren Buffett says it's consistently buying shares of a single mutual fund.

Now, you're probably wondering, "Is it really that simple?" The answer is yes, as long as you're purchasing S&P 500 low-cost index funds. Further, Buffett says to "keep buying it through thick and thin..especially thin..American business is going to do fine over time."

Index funds offer diversification and low fees, but the benefits don't end there. Mutual funds are considered less risky because you're investing in multiple companies' stocks and bonds rather than investing in those from a single company. Mutual funds also often charge lower fees because they run automatically by computers trying to match the performance of a financial market or index rather than by an individual.
