U.S. futures are higher despite the chaos in European markets following the resignation of the UK lawmaker who was leading Britain's exit negotiations with the European Union. The resignation came just hours after a Brexit deal was announced by Prime Minister Theresa May and could put her leadership in jeopardy. Investors in the U.S. will be watching the domestic economic calendar, which has a host of data on tap, including the weekly jobless claims, advance retail sales figures, the Empire and Philadelphia Fed manufacturing reports and the weekly natural gas and crude oil inventory reports. In early pre-market trading, Dow futures are 59 points above fair value, Nasdaq futures are 28 points above fair value and S&P futures are 4 points above fair value.
