'''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 [[wire]]s.<ref>The World Book Encyclopedia. 2001 ed. Vol. 4. Chicago: World Book, 2001. Print. Pages 1040-1041 </ref> 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."

"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 [[stock]]s.<ref>Ibid.</ref>
"Copper's downward trend foreshadows a [[stock market collapse]], according to Societe GeneraleSociété Générale's famously [[bear]]ish strategist Albert Edwards, who said [[equity]] markets will riot 'Japan-style.'" <blockquote>"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 [[asset]]s: time to get out of equities."<ref>[[Michael Snyder|Snyder, Michael]], "[http://theeconomiccollapseblog.com/archives/the-price-of-copper-and11-other-recession-indicators-that-are-flashing-red The Price Of Copper And 11 Other Recession Indicators That Are Flashing Red]".
