NEW YORK/LONDON, May 13 (Reuters) – Platinum and palladium both rose nearly 1.5 percent on Tuesday on the back of lingering supply worries as South Africa sent more police to the strike-hit platinum belt to protect miners after four were killed returning to work over the weekend.
Gold prices, meanwhile, were little changed as investors digested news U.S. retail sales braked sharply in April but that did little to change views the economy was poised for faster growth this quarter. Record high in U.S. equities, measured by the S&P 500 which rose above 1,900 for the first time, kept a lid on the metal.
