THE gold index of the JSE Securities Exchange jumped almost 5% on Friday, pushed higher by an increase in the price of the yellow metal. By 9.25am, the index had gained 4,84% or 56,6 points to 1_226,2, compared to the overall market, which was 0,23% weaker. ”The gold price is up because the dollar has weakened against other currencies,” said David le Roux, resources portfolio manager at Sanlam Investment Management. ”There is an inverse relationship between the strength of the dollar towards other currencies and the gold price,” he said. The world’s largest gold producer AngloGold gained 3,7% or R11 to R308, and rival Gold Fields climbed 5,74% to R37,75. Gold was last trading $273,15 a troy ounce versus Thursday’s New York close of $273,10 and Wednesday’s close of $268,10. Johannesburg stocks were untraded on Thursday as markets were closed for the Women’s Day public holiday. – Reuters
