Gold fell for the first time in four days after the metal’s rally toward $1,800 an ounce prompted some investors to sell the metal.

Immediate-delivery bullion lost as much as 0.4 percent to $1,784.20 an ounce, and traded at $1,787.90 at 9:09 a.m. in Singapore. Gold’s relative strength index has topped 70 since Aug. 5, a signal of a potential drop.

December-delivery gold shed as much as 0.4 percent to $1,786.80 an ounce, after closing at a record settlement of $1,793.80 yesterday as investors sought to hedge against accelerating prices. An index of producer prices in the U.S. gained 0.2 percent last month, compared to a 0.1 percent increase that economists in a Bloomberg News survey were expecting.
