While the major averages break their 50 day moving averages and technical analysts turn bearish, one commodity continues to show strength. Copper, the metal with a PhD due to its ability to accurately portray economic trends, continues to show strength.

Domestic and global sell-offs have been largely ignored by copper traders as demand remains strong. Does Dr. Copper know something about global strength that the equity markets are currently overlooking?
