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 MasterCard (NYSE: MA) 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 MasterCard.

When we looked at MasterCard last year, it weighed in with the same seven-point score. The card giant has navigated a tricky regulatory environment very well, but the challenges are far from over.

As a huge payment processor that's second only to Visa (NYSE: V), MasterCard has an enviable position in the global financial system. MasterCard makes money every time someone uses a credit or debit card in its network, yet takes no credit risk whatsoever. Moreover, as long as the company can convince customers to use plastic instead of cash, MasterCard can keep growing even if overall economic activity stagnates.

More importantly, MasterCard knows that the future goes beyond cards. With partnerships with Google and Citigroup (NYSE: C), MasterCard has moved confidently into the smartphone-based electronic wallet area. But the company still faces plenty of competition. eBay's (Nasdaq: EBAY) PayPal will fight to retain its lead in online payments, American Express (NYSE: AXP) has introduced a rival electronic wallet, and telcos AT&T (NYSE: T) and Verizon (NYSE: VZ) are also ready to try to take command of the emerging niche through their ISIS network.

Meanwhile, the backlash against credit and debit cards continues as debit card fee limitations take effect. Some analysts fear that the fallout could reduce card use and hurt revenues for MasterCard and its peers. But as long as money has to move somehow, MasterCard seems well poised to keep its fingers in the pie.

With an insignificant dividend and a fairly pricey valuation, MasterCard falls short of perfection. But if it can keep making the right moves, the company could easily keep improving in the years to come.
