NEW YORK ( Trefis) -- Here are this week's ETF winners and losers.
Fellow energy futures fund, United States Natural Gas Fund ( UNG) ran into turmoil this week as well. The fund is currently volleying between its 200- and 50-day moving averages. Like precious metals, energy will likely be closely watched in the week ahead. Investors looking to track oil and natural gas, however, should steer clear of USO and UNG. Equity-backed options such as iShares Dow Jones U.S. Oil Equipment & Services Index Fund ( IEZ) and First Trust ISE Revere Natural Gas Index Fund ( FCG) will likely prove to be more reliable options.
