SAN FRANCISCO (MarketWatch) -- December gold climbed $41.80, or 5.9%, to $746.80 an ounce Friday afternoon on Globex. "The major driving force in the gold market over the past day has been the drop of the U.S. dollar versus the euro," said Peter Spina, an analyst at GoldSeek.com. Gold neared "some terrific support around $700 and with the strength in the euro, it helped to motivate upside momentum."
