The number of people filing for unemployment benefits fell 5,000 to 249,000 this week, pushing the four-week average down by 3,000. Oil prices broke $50 a barrel for the first time in four months as fresh data showed U.S. crude inventories continuing to decline.  Walmart (WMT) - Get Report shares declined after the retailer said it expects "relatively flat" earnings growth in fiscal 2018 and is set to close 55 stores during the year.  Yum!
