The two ETFs, SPDR Gold (GLD) and Gold ETF (GDX), have done very well, as GDX has done better than GLD in 2009. GDX has gained 46% while GLD has gained 25%. However, there is now a new ETF that could serve you even better than the first two ETFs. It’s called continued to move upward.Market Vectors Junior Gold Miners ETF (GDXJ). Unlike the other two ETFs, GDXJ provides exposure to junior gold miners. Since these junior gold miners markets are smaller, the potential for their growth is much higher compared to other Gold ETFs. The portfolio of GDXJ consists of 39 different junior gold miners. GDXJ will experience more volatility than GDX and GLD since many companies in the portfolio are still in early stage without much revenue. For short-term investors, GDXJ has a higher potential compared to GDX. For long-term investors, I do not recommend GDXJ due to higher volatility. Instead, GLD could be more attractive in your .I do not own GDXJ as of today. But, I plan to buy shares of GDXJ sometime this week as a short-term investment. I am confident that as Gold prices continue its movement upward, GDXJ will definitely reap the benefit.
