Every investor would love to stumble upon the perfect stock. But will you ever really find a stock that provides everything you could possibly want?

One thing's for sure: You'll never discover truly great investments unless you actively look for them. Let's discuss the ideal qualities of a perfect stock, then decide if Molycorp (NYSE: MCP) fits the bill.

The quest for perfection
Stocks that look great based on one factor may prove horrible elsewhere, making due diligence a crucial part of your investing research. The best stocks excel in many different areas, including these important factors:

  • Growth. Expanding businesses show healthy revenue growth. While past growth is no guarantee that revenue will keep rising, it's certainly a better sign than a stagnant top line.
  • Margins. Higher sales mean nothing if a company can't produce profits from them. Strong margins ensure that company can turn revenue into profit.
  • Balance sheet. At debt-laden companies, banks and bondholders compete with shareholders for management's attention. Companies with strong balance sheets don't have to worry about the distraction of debt.
  • Money-making opportunities. Return on equity helps measure how well a company is finding opportunities to turn its resources into profitable business endeavors.
  • Valuation. You can't afford to pay too much for even the best companies. By using normalized figures, you can see how a stock's simple earnings multiple fits into a longer-term context.
  • Dividends. For tangible proof of profits, a check to shareholders every three months can't be beat. Companies with solid dividends and strong commitments to increasing payouts treat shareholders well.

With those factors in mind, let's take a closer look at Molycorp.

With only four points, Molycorp hasn't dug up particularly rare results. The rare-earth metal miner has gained a lot of attention lately, but so far, it's too early to tell whether the company will deliver on its ambitious promises.

Molycorp was part of Chevron (NYSE: CVX) until 2008, when it was put into the hands of private investors. The company went public in July 2010 to initial skepticism, but China's decision to restrict exports of rare-earth metals led to soaring interest in the company.

Now, stocks that have just about anything to do with rare-earth elements have done well. Rare Element Resources (AMEX: REE) has seen shares jump sharply in the past year. Even China Shen Zhou Mining (AMEX: SHZ), which doesn't actually mine anything that qualifies as a rare-earth element, has seen plenty of investor interest from investors who refuse to accept even the company's own guidance at face value.

A recent discovery, though, brings Molycorp's entire business model into question. Japanese researchers say that an undersea mother lode of 100 billion metric tons of rare-earth minerals is sitting at the bottom of the Pacific Ocean, waiting to be scooped up. That would especially hurt Rare Element Resources and Avalon Rare Metals (AMEX: AVL), which won't open their mines for years. But it obviously isn't good news for Molycorp, either.

Rare-earth elements are critical components for many popular products, so the quest to find more of them is reasonable. The question is whether Molycorp can act fast enough to cash in before competitors arrive on the scene.
