Why did WMT move on Jul 6, 2026?

Walmart's stock fell after Donald Trump posted on Truth Social that the retailer would be "lowering prices, by a lot" at his administration's request [1], [6], [8]. The post indicated that Walmart would be dropping prices on various items, including a nearly 15% reduction on a pound of ground beef [9], [11], raising immediate concerns about potential pressure on the company's profit margins. Walmart later confirmed these summer price rollbacks across its stores and Sam's Club locations [21], [22], [33].
