Copper was the darling of commodity traders. The price rallied from about $6,400 per ton to a record $10,190 in the past year, The Financial Times reports. Momentum was strong and it looked like there was no end in sight. But now, prices have dropped off a bit and miners are worried that the rally has hit a brick wall. The main concern is that what drove drove prices skyward -- China's demand -- may be slowing, according to the FT.

One indication of the slowdown is the amount of stocks held in exchange warehouses. At the LME Asia + Shanghai exchange warehouses, copper stocks have increased from below 150,000 to over 325,000 tons. That buildup has worried miners. The companies affected are Freeport MeMoRan (FCX), BHP Billiton (BHP), Xstrada (XSRAF), Anglo American and Brazil's Codelco, according to the Financial Times.

By now, most investors have heard the rallying cry of this market: "Just buy the dip!" However, the tape has been so strong that it can sometimes be difficult to find substantial dips that provide a good, low-risk entry point to begin building a position. But some potentially promising opportunities do exist. The first of these is an ETF that tracks the Indian stock market -- the iPath MSCI India Index ETN (INP).

This ETF has lost around 13% over the last three months and a little more than 4% during the last month. Year-to-date, it is down more than 14% as Indian stocks have been hurt by interest rate hikes, which have been instituted to try to tame inflation.

With the surge in copper prices -- and other industrial and precious metals -- it was no surprise that Freeport-McMoRan Copper & Gold (FCX) had a great quarter. Net income rose 60% to $1.55 billion or $3.25 per share. Excluding a $0.01 charge, the earnings handily beat the consensus of $3.03. As for the top line, revenues increased 22% to $5.6 billion. The Street estimate was for $5.47 billion.

Despite all this, the stock was off nearly 6% early Thursday. No doubt, one reason is that it has had a strong run over the past few months and the valuation was getting overextended.

"Last year's Chilean earthquake and the recent mine disaster have an important lesson: Countries with really good management should be strongly considered by investors," says Martin Hutchinson.

Hutchinson adds, "Well managed countries will be more efficient. they will use resources and labor better, there will be fewer sink-holes of value destruction in the public sector and the uncompetitive private sector and they will generally be more open to new ideas and new techniques.
