It's all about earnings for Diane King Hall when it comes to Thursday's top stories. United Airlines (UAL) saw turbulence in its stock after beating, coming in part from expectations that the airliner will take a hit from rising crude oil prices. In contrast, J.B. Hunt (JBHT) shares opened at a new all-time high. Diane then turns to new life in UnitedHealth (UNH), which tapped a 52-week high after reporting an earnings beat and guidance above Wall Street estimates.
