UnitedHealth Group Inc.'s stock surged 2.5% to an all-time high in morning trade Wednesday, as investors continued to cheer the company's decision to exit most Obamacare exchanges in 2017. The stock's price gain of $3.20 was adding about 22 points to the Dow Jones Industrial Average , which is a price-weighted index. That was more than offsetting the $2.29, or 4.9%, tumble in Coca-Cola Co.'s stock following disappointing first-quarter results. Coke's stock slide was shaving 16 points off the Dow. The Dow was up 15 points at a nine-month high. UnitedHealth's stock has now run up 14% year to date, while Coke shares have gained 3.4% and the Dow has advanced 3.7%.
