An analyst at Credit Suisse has come out with a report calling for Wal-Mart (WMT -0.39%) to buy Family Dollar (FDO.DL). While the company certainly has the financial means to do so, would the move even make sense for the business? In this video from Wednesday's Investor Beat, host Chris Hill and Motley Fool analyst Bill Barker discuss how the move could actually fill in some key gaps in Wal-Mart's offerings both geographically and in terms of products. They also discuss Wal-Mart as a whole, and whether investors should continue to look at this stock as a growth story.
