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 AT&T (NYSE: T) 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 AT&T.

When we looked at AT&T last year, it had a much better score of 6. Falling margins and weaker returns on equity are responsible for the point drops, and the telecom's minimal growth in the past year continues a disturbing trend.

AT&T has cast its lot with the high-growth mobile trend, largely ceding its legacy landline business to smaller competitors like CenturyLink (NYSE: CTL) and Frontier Communications (NYSE: FTR). Its focus on building out its wireless network was instrumental in gaining first-mover status to carry Apple's (Nasdaq: AAPL) iPhone exclusively, although the tech giant has since opened up the field to make its iPhone 4S available on Verizon (NYSE: VZ) and Sprint Nextel's (NYSE: S) networks as well.

Unfortunately, AT&T hasn't delivered the numbers that investors have hoped for. In its most recent earnings report, the company fell short on revenue and only matched earnings-per-share estimates. But with the late release of the iPhone 4S, everyone expects the fourth quarter to come in much stronger, with the potential for record-breaking sales. In addition, Android-phone sales accounted for about half of the company's total handsets sold.

Despite the ongoing controversy with its proposed takeover of T-Mobile, AT&T's future success lies with its broader strategy to bring bundles of services, including voice, video, and high-speed data not just to mobile devices but to households as well. If it can do so while overcoming a spotty reputation for service, AT&T could find itself closer to perfection in the years to come.
