Gold and silver recouped early losses on Friday, but were headed for a second straight week of declines as a global rout in tech equities and a stronger US dollar wiped out gains made by the metals during a brief rebound earlier this week. Spot gold rose 0.4% to $4,790.80 per ounce by 0224 GMT, but was down 1.4% for the week. U.S. gold futures for April delivery fell 1.7% to $4,806.50 per ounce
