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.

Freeport McMoran Copper (FCX) is involved in mining, smelting and refining of coper, gold and molybdenum. The company runs its mining and smelting operations in North and South America, Indonesia and Africa. Freeport competes with other miners such as Southern Copper (SCCO), Codelco and Newmont Mining (NEM).

Freeport's extensive copper mining operations are its biggest source of value – more than 73% of our $63.42 base price estimate for Freeport's stock. Our price estimate currently stands about 25% ahead of market price. The company's mining and production of gold makes up for most of its remaining value. Here we try and explain how the outlook for gold prices in the years to come can affect Freeport's stock price.

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.

The earnings season ramps up this week. Analysts polled by Thomson Reuters foresee strong reports from such big names as Apple (AAPL), eBay (EBAY), IBM (IBM), General Electric (GE), Google (GOOG), Schlumberger (SLB) and Southwest Airlines (LUV). And fast on the heels of last week's big earnings beat from JPMorgan Chase (JPM), there will be plenty more results from the financial sector to peruse this week.

Among the financials expected to post double-digit earnings growth this week are Capital One Financial (COF), Morgan Stanley (MS), SLM Corp. (SLM) and U.S. Bancorp (USB), but the week's biggest earnings winner may be Wells Fargo (WFC).

"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.

Investors will recall the massive rally in the euro which began at the beginning of June when bearish sentiment reached overwhelming levels. Could a similar pattern take place in the U.S. Dollar? If it does, investors who go long the dollar at these levels will be richly rewarded for taking a contrarian stand on the greenback.

The simplest instrument to use in order to gain exposure to a potential dollar rally is likely the PowerShares DB US Dollar Index Bullish ETF (UUP), which tracks the performance of the greenback versus a basket of foreign currencies. The UUP gained 1.70% on Tuesday, potentially signaling a trend reversal. Investors could also consider buying call options on the ETF in order to leverage their upside.

The take-no-prisoners stock market has claimed another stock, but in this case, if you purchased Freeport McMoRan (FCX) when first discussed here on March 23, 2009 at a price of $41.87, you retained your shirt.

Freeport was stopped-out for a gain in June at the raised sell/stop loss of $63 amid the Dow's recent decline.

Further, the view from here still argues that the future remains bright for FCX, the world's second largest copper producer.
