U.S. stocks turned higher Tuesday afternoon, with the Nasdaq making its largest rebound in five years, as investors weighed upbeat earnings from Dow components Coca-Cola and Johnson & Johnson against disappointing reads on builder sentiment and New York-area manufacturing, while tracking events in Ukraine.

Reports of pro-Russian separatists briefly taking control of an airfield in eastern Ukraine weighed on investor sentiment early on, but the mood shifted Tuesday afternoon, when investors were heartened that "the worst case scenario hasn't come to fruition," said Art Hogan, chief market strategist at Wunderlich Securities.
