Here's a look at the best and worst of exchange-traded funds this week.
PowerShares DB Oil ( DBO) -7.4% iPath Nickel ( JJN) -12.7%. Market Vectors Russia ( RSX) -12.5%. Market Vectors Gold Miners ( GDX) -8.3%. U.S. Natural Gas ( UNG) -6%. Obviously, if DTO were a winner, oil ETFs were losers. The unemployment report from July 2 continued to generate news all week, and the skeptical take on the recovery dominated. Energy prices were hit hard as prices tumbled quickly, and there was barely any rebound.
