Worries over European banks sent the price of gold higher Thursday, and gold mining stocks went up along with the precious metal. But they reversed by the end of the day. Randgold Resources (GOLD) fell 1.14 to close at 87.04 after setting a 52-week high. The U.K.-based company owns big stakes in mines in Mali and the Ivory Coast. Earnings lagged in 2013, but are expected to grow 16% this year and 33% next year.
