Walmart will report fiscal second-quarter earnings before the bell on Thursday. The largest U.S. retailer warned in May that it would have to raise prices because of President Trump's higher tariffs on imports from other countries.

After mixed reports from retail rivals, Walmart reported better-than-expected quarterly results and raised its sales forecast for the year.

Big-box retailer Walmart reported solid revenue growth Thursday and said that it expects better sales and earnings for the full year, as customers feel the squeeze from higher tariffs imposed by US President Donald Trump.
