NEW YORK (TheStreet) -- Here are this week's winners and losers.
United States Natural Gas Fund ( UNG) -5.1% Although energy stocks managed to climb over the past week, natural gas futures struggled to find footing. Both UNG and the iPath Dow Jones U.S. Natural Gas Subindex Total Return ETN ( GAZ) are currently trading at all-time lows. The equity-backed First Trust ISE Revere Natural Gas Index Fund ( FCG) fared better than its futures-based cousins. This week, the fund saw 2% gains. Written by Don Dion in Williamstown, Mass.
