Seeking out the 10 mid caps to rule them all is the only logical follow-up to seeking the 10 small caps to rule them all. Unlike small-cap companies that offer investors the potential for high-risk, high-reward returns, mid-cap companies usually have significantly less risk built in because of their proven business track records. These companies either offer distinctive products or exceptional value to investors – or possibly both.

For reference, here was last week's choice to kick off this series:

This week, I want to highlight a company that I touted as the best stock in 2011 nearly six months ago, Thompson Creek Metals (NYSE: TC).

What it does
Thompson Creek Metals is looking to amass its fortune by being one of the premier suppliers of molybdenum -- a white metal often used to strengthen steel. Whereas countless mining companies are digging up gold and silver, Thompson is focusing on the practical applications of its minerals. Molybdenum may not be as sexy as gold in terms of tradability, but its practical applications are potentially more useful.

How it stacks up
There are two main drivers that will determine if Thompson Creek is successful: molybdenum spot prices and copper prices.

Precious metal pricing has a direct effect on the profitability of all miners, and Thompson Creek is no different. Molybdenum prices have recently been on the rise, and that bodes well for the company. Since 2009 moly prices have doubled, and they've risen by an additional 4% since the beginning of this year.

Copper prices will likely have a strong impact on Thompson Creek's future as well. With the acquisition of the Mt. Milligan mine from Terrane Metals last year, the company gained access to 2.1 billion pounds of copper reserves. Copper, like moly, is a ready-to-use asset, which puts Thompson Creek in the driver's seat of its own destiny.

It's not just that Thompson Creek has the materials to drive growth; it's that the company is head and shoulders above its competitors:


Forward P/E


Thompson Creek Metals 9.5 $303 million / $20.5 million
General Moly (AMEX: GMO) N/A $64.3 million / $10.7 million
Freeport-McMoRan (NYSE: FCX) 7.8 $4.09 billion / $4.75 billion
Southern Copper (Nasdaq: SCCO) 9.2 $2.19 billion / $2.76 billion
MolyCorp (NYSE: MCP) 16.4 $492.5 million / $2.9 million

Sure you may find lower P/E ratios among its competitors, but in the case of Freeport-McMoran and Southern Copper, you'll pay the price of burdensome debt. MolyCorp may offer you a strong cash position, but are you willing to pay a 16-plus forward multiple when the rest of the sector trades at nearly half that level? General Moly shows promise, but at this point in time it's just burning through its cash pile. Thompson Creek is the clear leader of this bunch which leads me to my next point...

How it could make you money
We have had no shortage of natural disasters worldwide this year, and the rebuilding effort in Japan and around the globe will involve steel products -- steel likely alloyed with molybdenum. But Thompson's potential customers aren't just in devastated regions. In the United States and worldwide, the need to renovate aging bridges and infrastructure is growing. This creates an almost constant demand for steel and therefore, Thompson's products.

Copper will always play a large role in Thompson's future growth plans. Currently pegged to be in production sometime in 2013, Mt. Milligan will add diversity to Thompson's already profitable portfolio and should allow the company to take advantage of these near-record copper prices.

The thing to remember when investing in Thompson Creek is that you're buying into a practical use metal. No one ever said investing had to be sexy to be profitable -- certainly not Thompson Creek or myself -- but given the company's long-term prospects, it absolutely deserves a spot among my 10 mid caps to rule them all.
