Gold edged higher as caution dogged the financial markets ahead of U.S. growth data due later, having earlier hit a near four-month low as a better economic outlook dented safe-haven buying of the metal.

Spot gold was bid at $1,313.50 an ounce at 1220 GMT against $1,312.24 late in New York on Thursday. U.S. gold futures for February delivery fell $5.20 to $1,313.20.

The metal had touched a low of $1,308.00 an ounce, having fallen 2.6 percent on Thursday after a run of firmer than expected U.S. economic data boosted confidence in the recovery.

Physical gold buying in Asia lent some support to prices on Friday as the previous session's dip attracted some buyers back to the market, though Chinese buying is expected to ease after the Lunar New Year next week.
