Wal-Mart (NYSE:WMT) recently reported its fourth straight quarter of falling same-store sales, one of the worst signs of trouble for any retailer. The biggest challenge is that online retailers such as Amazon.com (NASDAQ:AMZN) are taking over the title as low-cost king, a crown once held by Wal-Mart. 

On the higher end, long-term, Target (NYSE:TGT) is taking more affluent consumers, who before the data breach were going to its stores and boosting same-store sales. 

The question now is whether Wal-Mart can turn the ship around. Fool contributor Travis Hoium gives his thoughts in the following video.
