Bank of America Merrill Lynch on Wednesday upgraded Wal-Mart to buy from neutral, citing the potential for the U.S. retailer to continue to deliver double-digit growth in its e-commerce business.
"We believe WMT is embarking on a period of sustainable 20-30%+ e-com growth," equity analyst Robert Ohmes wrote in a research note.
On Tuesday, Wal-Mart reported fiscal fourth-quarter earnings that exceeded analysts' expectations driven by a 29 percent rise in U.S. e-commerce sales and a 36 percent increase in gross merchandise volume.
Bank of America says last quarter GMV growth for "Walmart Grocery," Wal-Mart's grocery app and website, outpaced GMV growth for "Amazon Fresh," Amazon's grocery delivery service, another encouraging sign that Wal-Mart's online strategy is paying off.
