In this video as part of The Motley Fool's "Ask a Fool" series, senior advisor to The Motley Fool's Rule Your Retirement service Robert Brokamp takes a question from a Foolish reader, who asks: "I am looking for a long-term dividend fund for my 401(k). I am 12 to 13 years from retirement and would like a dividend fund for my 401(k) or a Roth that I plan to set up. Do you have any suggestions or advice?"
