Walmart's stock surge to reduce Dow's losses by about 30 points

Shares of Walmart Inc. shot up in premarket trade Tuesday after the discount retail giant reported fiscal fourth-quarter results and raised its dividend, with the implied price gain providing a 30-points boost to the Dow Jones Industrial Average's price. But that wasn't enough to lift Dow futures into positive territory, as they were still down about 59 points. A gain in Walmart's stock Tuesday would be the sixth straight, the longest win streak since the 7-day stretch ending Nov. 9, 2018. The stock was on track for the best 6-day performance--up 9.2%--since it ran up 9.9% during the six days ending Aug. 17, 2018.
