First Trust ISE-Revere Natural Gas Index Fund (NYSEArca: FCG)
April gain: 9.2%
Comment: FCG was April’s top-performing non-leveraged sector ETF and the United States Natural Gas Fund (NYSEArca: UNG) was the second-best commodities fund after JO. Without a substantial increase in supply, natural gas inventory levels could rise to 3.422 trillion cubic feet by late October, or 11% short of last year’s levels for the same period, according to the Energy Information Agency. That bodes well for the medium-term prospects for UNG and FCG. [Low Production Outlook is Supporting Natural Gas ETFs]
