"The technical picture for gold is getting better by the day," says Eric Roseman. In his Commodity Trend Alert, he notes, "The last 16 months have been painfully boring for gold bugs. But every asset class has its day, and right now it's time for gold to shine once again."

The advisor considers Eldorado Gold (ASE: EGO) a speculative favorite. He explains, "Eldorado Gold is a $1.7 billion dollar company with operations in Brazil, China and Turkey. Management is strong, and despite a recent political spat with the Turkish government in July, earnings are booming."

He continues, "The stock is a perfect addition to our mining portfolio because it earns a net profit, has tangible reserves and has boosted its free cash flow."

In August, he observes, EGO reported strong Q2 results with net income rising to a record $26.7 million dollars, or $0.08 per share compared to $0.00 a year earlier. He states, "During the second quarter, Eldorado sold 112,702 ounces at an average price of $664 an ounce – one heck of a healthy margin."
