SAN FRANCISCO (MarketWatch) -- Gold futures edged lower Monday, pulling back a bit after Friday's sharp rally, while oil futures wavered between small gains and losses following declines over the past four sessions. Gold for August delivery GCQ2 -0.19% fell $2.60, or 0.2%, to $1,619.50 an ounce on the Comex division of the New York Mercantile Exchange after dropping 3.7% on Friday. July crude oil CLN2 -0.41% traded at $83.05 a barrel on Nymex, down 18 cents, or 0.2%. Prices lost over 8% last week as recent economic data raised expectations for a slowdown in oil demand.
