Walmart (NYSE: WMT) generated a good momentum in the 4Q despite the confusing spending backdrop experienced during the period, so its upcoming 4Q print and FY outlook should provide more optimism on the sustainability of its recent share gains, UBS analysts say in a research note. The biggest U.S. retailer should benefit from its defensive characteristics and idiosyncratic sales and profit drivers as it expands its marketplace, analysts say. “We think the company may provide more detail on its alternative profit story that could keep the stock’s valuation trading at a premium,” analysts add.
