Investors are spooked that a cooling off of Walmart’s online sales could mean the company isn’t positioned to fend off Amazon’s internet dominance after all. That fear sent shares tumbling more than 9 percent Tuesday, when Walmart said e-commerce sales grew just 23 percent during the latest quarter, lagging prior periods’ results. But analysts and industry experts alike have been quick to point out Walmart is planning a number of investments in its website and overall e-commerce operations that should start to take hold later this year. “It’s a well-positioned huge foundation,” said Oliver Chen of Cowen & Co. “What’s ahead is technology … further digitization of supply chain, & strategic use of M&A to drive [e-commerce] share.” People are still underestimating the value of Walmart’s store fleet — something Amazon doesn’t have — and how bricks and mortar will aid the company in fulfilling more grocery orders and same-day deliveries, Chen wrote in a note to clients. “The theme here is leverage of WMT’s physical assets and our view is that the future of eCommerce is physical + digital – this strategy will drive a ‘productivity loop.'” A 23 percent increase in e-commerce sales during the fourth quarter pales in comparison with Walmart’s reported growth of 50 percent in the previous quarter.
