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 Hologic (Nasdaq: HOLX) 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 Hologic.

With only three points, Hologic doesn't paint a perfect picture for investors. The medical imaging company has seen growth slow substantially during the recession, although its future prospects may be getting just a little brighter.

Hologic has a fairly wide range of health-care operations. With everything from mammography systems and cervical cancer test diagnostics to bone density measuring devices, Hologic focuses on women's health care. It also developed a drug to reduce risks of singleton spontaneous preterm birth for KV Pharmaceutical (NYSE: KV-A), which took over all rights to the drug after it gained FDA approval.

Of course, the company has plenty of competition. In mammography, giants like General Electric (NYSE: GE) and Fuji make competitive products. CR Bard (NYSE: BCR), Becton Dickinson (NYSE: BDX), and Abbott Labs (NYSE: ABT) offer rival products in other lines of business.

Earlier this week, Hologic saw a nice gain after it announced earnings that beat expectations. Moreover, although the company issued full-year fiscal 2012 guidance below what analysts were hoping for, growth across the full spectrum of its operating units is definitely a good sign.

For Hologic to reach perfection, it ideally needs to see a healthier economy lead to more health-care spending. With forward earnings looking much more reasonable and the potential for improving returns on equity, Hologic could see major score improvement in the future.
