Copper, the 29th element, is a metal. In industry it is praised for its extreme ductility and electrical conductivity which make it an excellent material for wires. Copper is also a nutrient mineral, and is required by the human body to perform certain chemical reactions.
Copper is also important culturally, as one of the first metals to be used by humankind, especially in its alloy form bronze. Even today the pennies in the United States are informally referred to as "coppers."
The Price of Copper and the U.S. Economy
The price of copper has traditionally been one of the very best economic indicator of the future performance of the U.S. economy. Many analysts are concerned.. "Copper is viewed by some analysts as a signal of turning points in the world economy, as well as an indicator of whether it is safe to buy cyclical industrial stocks."Copper's downward trend foreshadows a stock market collapse, according to Societe Generale's famously bearish strategist Albert Edwards, who said equity markets will riot 'Japan-style.'"
"Copper is acting exactly as it did when I wrote about the impotence of liquidity in the face of the (then imminent) 2007 recession. Once again it is giving us an early warning that liquidity will not save risky assets: time to get out of equities."
