Manufacturing rises in U.S.

U.S. manufacturing had modest gains in December, boosting the economy at the start of the new year.

The Institute for Supply Management said Wednesday that its index of manufacturing activity rose to 50.7 in December from 49.5 in the previous month. November's reading was the lowest reading since July 2009, one month after the recession ended.

A reading above 50 signals expansion.
