SAN FRANCISCO (MarketWatch) -- Gold and crude-oil futures added to gains after a gauge of manufacturing activity in the U.S. showed acceleration. Crude for January delivery CL2F +0.55% rose 69 cents, or 0.7%, to $101.06 a barrel on the New York Mercantile Exchange. It had earlier traded below $101, wavering in and out of the red. Gold, which also seesawed in early trading, also added to gains, with the February contract GC2G +0.27% rising $4.50, or 0.3%, to $1,754.30 an ounce on the Comex division of the Nymex. The Institute for Supply Management's manufacturing index rose to 52.7 from 50.8 in October, its 28th month of expansion.
