Market Vectors Gold Miners ( GDX) -7.7% Market Vectors Junior Gold Miners ( GDXJ) -11.6% A stronger U.S. dollar sent commodities broadly lower, and gold bullion ETFs lost about 3% on the week. Miners were hit hard by a trifecta of a fall in gold prices, the larger decline in commodities and the decline in stocks. Market Vectors Solar ( KWT) -13.2% Claymore/MAC Global Solar ( TAN) -11.7% In the previous week, France cut its subsidies to solar power makers, and Germany was expected to follow. This week, Germany delivered with the cuts and an already jittery market slammed solar shares. The news overshadowed a positive change for the solar industry in Ontario, where the government passed a $10 billion alternative energy deal with Samsung.
