Gold futures up a third session in a row

Gold futures ended higher Thursday for a third session in a row, finding support as the U.S. dollar weakened and Treasury yields pulled back ahead of Federal Reserve Jerome Powell's speech at the Jackson Hole economic symposium Friday. Powell may provide clues on the plan for U.S. interest rates. December gold climbed by $9.90, or 0.6%, to settle at $1,771.40 an ounce.
