BHP Billiton, the world's biggest mining company, spends 61 cents to produce a pound of copper and sells it for $3.15.
The market's largest-ever profit margin is evidence copper is headed for a record plunge, perhaps as much as 25 percent in a day, said John Tumazos, the Prudential Equity Group LLP analyst who made Institutional Investor magazine's quarterly All-America Research Team 40 times. Copper doubled in the past year on betting by speculators, the 50-year-old Tumazos said.
After a fivefold increase since 2001 to a record high in May, copper fell 11 percent in one week, the most ever and a sign that the rally may be over. The volatility, or rate at which a price moves up or down, of copper the past 10 weeks is the highest in history, according to data compiled by Bloomberg. Prices fluctuated by 48.5 percent in the week ended May 26.
"I've never seen anything quite like this in my entire life," said Leonard Kaplan, 55, president of Prospector Asset Management in Evanston, Illinois, who's been trading metals for 30 years. The volatility of the 1980s "was news-related. Now, you have extreme volatility for no apparent reason at all. The appetite for risk is greater than these markets can absorb."
A crash in the copper market – a 25 percent drop would be bigger than the 1987 stock-market bust – would hurt speculators and producers. A price correction also would provide relief for users including Tyco International Ltd., the biggest maker of electronic connectors, and for central bankers concerned about accelerating inflation.
In New York, copper for July delivery on the Comex division of the New York Mercantile Exchange rose as much as 4.35 cents, or 1.2 percent, to $3.63 a pound in after-hours trade at 12:34 p.m. Sydney time today.
Popular with funds
Pension funds and hedge funds helped fuel the copper rally by shifting assets out of stocks and bonds into commodities in search of greater returns. HSBC Holdings Plc, Europe's largest bank by market value, said in a May 24 report about $100 billion will be invested in commodity indexes by the end of 2006, compared with $10 billion at the end of 2003.
"Expect metal-price volatility to be high with the threat of a hefty correction to be ever present," the HSBC analysts, led by Paul McTaggart in London, said in the report.
Prices sank as much as 9 percent on May 24. The day before, copper surged a record 12 percent. While a drop is likely to hurt earnings at Melbourne-based BHP Billiton and Chile's Codelco, the world's biggest copper company, producers say the rally isn't over.
BHP Billiton unfazed
"We are seeing very good economic conditions around the world," said Charles "Chip" Goodyear, the company's chief executive. "The supply side is still struggling to keep up."
Global copper production has been curbed by a strike lasting more than two months at Grupo Mexico SA and a drop in supply from Freeport-McMoRan Copper & Gold Inc.'s Grasberg works, the world's No. 2 copper mine.
A drop in price "would make our life easier," said Bo Samuelsson, president of Helsingborg, Sweden-based Elektrokoppar AB, a maker of cable that buys 140,000 tons of copper a year. Price gains "increase our credit risk tremendously. Your customers may have very good credit but one day, prices suddenly double and change the credit picture."
Tumazos predicted in August copper would average $2 a pound this year. Prices have averaged $2.63 on the Comex division of the New York Mercantile Exchange and reached a record $4.04 a pound on May 11.
'It's fairyland'
"It's fairyland," said Richard Elman, chief executive officer of Hong Kong-based Noble Group Ltd. "We think, ultimately, prices will come back to reality. The economies are fairly strong, but it doesn't justify the price for a lot of these commodities."
A 25 percent drop would produce a return of about 100 percent for a speculator who is selling New York futures. A sale of one July contract would result in a profit of about $22,400, almost twice the exchange-required deposit of $12,150.
"The bull market has reached the stage where you are seeing very, very high volatility," said David Harding of London-based Winton Capital Management, which invests $5.5 billion in hedge funds. "That is characteristic of a more advanced stage in a bull market."
Price volatility often shows that a market has peaked. In 1998, 10-week volatility for soybeans doubled to 28 percent in the six weeks before the market declined. Fluctuations in the price of corn doubled in the weeks ahead of the 2005 and 2004 highs in price. Volatility on the Nasdaq also nearly doubled to 78.41 percent at the time of the April 12, 2000, all-time high, from 40.59 percent at the start of February that year.
Benchmark for commodities
Copper, a benchmark for commodities, may be indicating a decline in other markets. Zinc, which more than doubled in the past 12 months, climbed to a record $4,000 a ton May 11. The contract plunged as much as 12 percent four sessions later.
Silver surged 77 percent in the past 12 months, rising to $15.22 an ounce, the highest in 23 years. It dropped as much as 8.9 percent May 15. Copper has even become a signal for gold prices. The correlation between gold and three-month copper has been 0.789 this year, compared with 0.624 in the past 12 months, according to Bloomberg data. A correlation of 1 would indicate the two metals are moving in lockstep.
"Copper always seems to be the first one to move," said Jon Bergtheil, head of global metals strategy at JPMorgan Chase & Co. in London. "Copper is always the best barometer. It doesn't seem to be different in this cycle."
Copper for three-month delivery soared to a record high $8,800 a ton in London on May 11. The metal has lost almost 12 percent since then on speculation that demand will slow as rising borrowing costs hurts investment and economic growth.
Interest rates
The U.S. Federal Reserve on May 10 raised its key interest rate a 16th time, to 5 percent. The Bank of Canada last week raised its main rate a quarter percentage point to 4.25 percent, the highest in almost five years. European Central Bank policy makers have indicated they will raise rates in June.
"The strong rise in interest rates since the beginning of the year appears to be causing problems for a growing number of property markets around the globe," said Jochen Hitzfeld, a commodity strategist at HVB in Munich. "Slowing growth in the construction industry will hurt copper demand."
Global orders for copper will rise 5.2 percent this year, HSBC forecasts. Growth in China, the world's biggest copper user, increased consumption for use in everything from bridges to appliances. The country's economy expanded 10.3 percent in the first three months of 2006.
"The fundamentals for the global economy still look very positive and that means in an underlying sense commodity prices will keep rising, which will buoy the metals markets," said Rob Henderson, chief markets economist at National Australia Bank Ltd. in Sydney.
Market strategists say that even if demand increases, the rapid changes in copper prices are a bad sign.
"You're getting these whipsaw moves," said Michael Guido, director of hedge fund marketing and commodity strategy at Societe Generale in New York. "It's freaking a lot of people out."
