Dow jumps by more than 500 points at peak, putting blue chips on track for best day since March

The Dow Jones Industrial Average was trading sharply higher midday Tuesday, putting blue chips on track to book the best one-day gain since March. The Dow was up about 492 points, or 2%, at 25,739. If it holds the gain would represent the best point and percentage climb since March 26. Tuesday's rally was partly on the back of a surge in shares of component UnitedHealth Group Inc., which was delivering a roughly 70-point jolt to the price-weighted equity gauge. Share rises for UnitedHealth come after the health-care company raised its full-year earnings outlook and said it continues to see growth in health-care plan membership and premiums. Meanwhile, the S&P 500 index was climbing 2% at 2,804 and the Nasdaq Composite Index advanced by 2.6% to 7,620. Wall Street investors appear to be focusing upbeat earnings, including those from Goldman Sachs Group Inc. , Johnson & Johnson and Morgan Stanley .
