NEW YORK (MarketWatch) -- The dollar extended losses on Friday after a report showed U.S. consumer spending rose less than economists expected in December. The dollar index (DXY 79.31, -0.14, -0.17%) , which measures the greenback versus a basket of other major currencies, fell 0.3% to 79.245. The report also said consumer prices rose 0.1%. Still to come is the Institute for Supply Management's index on the manufacturing sector.
