Dan Sullivan, a specialist in relative strength rankings, maintains a position in Freeport-McMoRan Copper and Gold (NYSE: FCX) in his model portfolio. The editor of The Chartist explains, "The world's largest publicly traded copper company, Freeport-McMoRan operates large, long-lived and geographically diverse assets around the world.

"The company owns significant proven and probably reserves of copper, gold, and molybdenum and has an extensive portfolio of expansion and growth projects.

"The company conducts its operations primarily through its principal operating subsidiaries, PT Freeport Indonesia, Phelps Dodge, and Atlantic Copper. PT Freeport Indonesia's principal asset is the world-class Grasberg mine which was discovered in 1988.

"This mine contains the world's largest single copper reserve and the world's largest single gold reserve. It is also a 25% owner of PT Smelting, which operates a copper smelter and refinery in Gresik, Indonesia.

"Phelps Dodge is a fully integrated producer of copper and molybdenum, with mines and processing facilities in North and South America and Europe. Atlantic Copper operates a copper smelter and refinery in Huelva, Spain.

"The company's second-quarter profit surged year-over-year due to the acquisition of Phelps Dodge and increased metal pricing. Net income rose to $1.10 billion, up from $367 million in the year-ago period. Revenue also surged to $5.81 billion, from $1.43 billion last year."
