NEW YORK (TheStreet) -- Welcome to Don Dion's "ETF Winners and Losers." Be sure to stop by throughout the week to find out which ETFs are gaining or losing.
Market Vectors Junior Gold Miners ETF ( GDXJ) -1.6% Gold broke through the closely-watched 200-day moving average recently, leading many investors to question the long-term strength of the popular precious metal. As we approach the weekend, physically-based gold ETFs like the iShares Gold Trust ( IAU) are hovering in relatively unchanged territory. Gold miners, however, are heading south. Leading the retreat are the smallest and most volatile industry players. All prices as of 2:15 PM EST Written by Don Dion in Williamstown, Mass.
