Amazon has recently added groceries to its vast list of items available on the retail giant’s website, much to Wal-Mart’s chagrin. Wal-Mart has experienced a sales decline this past quarter, marking the fifth quarter in a row with negative growth. Investment bank Goldman Sachs downgraded their signal on Wal-Mart stock from buy to hold. Pessimistic projections from industry experts are mounting. However, Wal-Mart has remained steadfast in their optimism. To the critics, they retort that online sales have seen a 25% increase over the previous two quarters. On top of that, they’re expanding their new “neighborhood markets” by 300 stores nationwide in an attempt to woo some of their lost customer base who turn to Amazon or Dollar Tree for the lowest prices. It’s important to keep in mind however that Wal-Mart is still clearing $469 billion in sales annually, and isn’t likely to easily succumb to pressure.
