A rally in exchange traded funds that invest in gold miners has carried the sector ETFs close to their all-time highs from late 2010.

Market Vectors Gold Miners ETF (NYSEArca: GDX) is reasserting its relative uptrend against the S&P 500 as the fund eyes a new record relative high, said Tarquin Coe, technical analyst at Investors Intelligence. The ETF was listed in 2006. [Miner, Silver ETFs Pick Up Momentum]

“Last week the ETF’s 50-day exponential moving average rose up through the 200-day exponential moving average, printing a’ golden cross,’ a bullish signal,” Coe wrote in a newsletter Monday. “U.S. debt uncertainties are providing a tailwind to yellow metal related stocks and that should be enough to soon drive the fund beyond the all-time high of $64.62 a share.”

Market Vectors Junior Gold Miners ETF (NYSEArca: GDXJ) invests in small-cap miner stocks.
