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 Optimer Pharmaceuticals (NASDAQ: OPTR) 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 Optimer Pharmaceuticals.

Since we looked at Optimer Pharmaceuticals last year, the company has kept its five-point score. The stock hasn't been so fortunate, dropping nearly 20% over the past year.

Optimer focuses on trying to create medications to fight bacteria. The company is best known for Dificid, its treatment for a form of diarrhea associated with the Clostridium difficile bacterium. Alongside marketing partner Cubist Pharmaceuticals (CBST.DL), Optimer got approval in the U.S. in mid-2011 and has been trying to ramp up sales ever since.

But Optimer has faced some difficulties recently. Back in April, the board of directors fired the company's board chairman, Michael Chang, as well as its CFO and a vice president because of governance concerns raised by the grant of 1.5 million shares of subsidiary Optimer Biotechnology to Chang.

More crucially, though, Optimer hasn't seen the sales results from Dificid that it has hoped for. Although the company did studies showing Dificid's superiority to ViroPharma's (NASDAQ: VPHM) Vancocin, which Eli Lilly (LLY -1.81%) developed decades ago, the fact that generic versions of the competing drug are available at much lower cost present a problem for doctors considering Dificid.

Even with those cost concerns, analysts took issue last week with Optimer's recent decision to cut prices on Dificid. Dendreon's (NASDAQ: DNDN) sales woes with its high-priced Provenge cancer treatments may suggest that cutting price can be a driver to get doctors to adopt a new drug. Yet given the company's failure to turn revenue into net income even at current prices, a 25% price reduction for hospital customers could threaten margins even if it results in greater sales volume.

For Optimer to improve, it will be essential for it to find a viable strategy for marketing Dificid that produces profitable results. Without that, Optimer will likely never get much closer to perfection.
