About a year ago in a tax sheltered account I bought the premier copper stock, a carefully chosen silver ETF, a carefully selected gold ETF, and a leading independent oil company all in a single investment account, as a dollar denominated commodity play hedging against the falling dollar, and against the continued folly of triple deficit US economy political policy during a world-class recession. The account is at 150% of investment now and all remains a good long-term hold for dollars. Fundamentals are still the same.
You have FCX.....look for GDXJ
