Gold dragged down by dollar spike, profit-taking

Gold slid on Friday, closing its worst week since June, as profit-taking by investors and a spike in the U.S. dollar outweighed the desire for a safer haven. Gold tumbled in early U.S. hours on apparent investor liquidation, but clawed back much of its loss by mid-afternoon as the resignation of European Central Bank policymaker Juergen Stark reignited aversion to riskier assets.
