Gold advanced for the second straight session after economic reports signaled improving prospects for demand in China and the US. The Institute for Supply Management's factory index rose to 53.4 in March from 52.4 a month earlier, the Tempe, Arizona- based group's data showed today. Fifty is the dividing line between growth and contraction. China's logistics federation and the National Bureau of Statistics said a Purchasing Managers' Index touched a one-year high of 53.1 last month. “There is a sense of relief that the growth story in the US is intact, and the Chinese numbers are helpful,” Sterling Smith, a market analyst at Country Hedging in St. Paul, Minnesota, said.
