SYDNEY (MarketWatch) -- Gold futures rebounded in electronic trading Wednesday, supported by a weaker dollar. Gold for April delivery GCJ2 +0.43% added $5.20, or 0.3%, to $1,652.30 an ounce on the Comex division of the New York Mercantile Exchange during Asian trading hours. The dollar index DXY -0.25% which measures the U.S. unit against a basket of rivals, traded at 79.410, from 79.582 in late North American trading Tuesday. A weaker greenback tends to encourage buying in dollar-priced commodities as it makes them cheaper to holders of other currencies. Silver tracked gold higher, with the May futures contract SIK2 +1.29% adding 29 cents, or 0.9%, to $32.13 an ounce.
