Sales at U.S. retailers rose 0.4% in December to mark the fourth straight gain. The increase was a notch below the forecast of 0.5%, but sales for November and October were both revised higher. Excluding autos and gasoline, retail sales also rose 0.4% last month. The consumer price index, meanwhile, rose 0.1% in December, with four-fifths of the increase tied to the highest cost of housing. The increase matched the forecast.
