Everyone would love to find the perfect stock. But will you ever really find a stock that gives you everything you could possibly want?

One thing's for sure: If you don't look, you'll never find truly great investments. So let's first take a look at what you'd want to see from a perfect stock, and then decide if Panera Bread (Nasdaq: PNRA) fits the bill.

The quest for perfection
When you're looking for great stocks, you have to do your due diligence. It's not enough to rely on a single measure, because a stock that looks great based on one factor may turn out to be horrible in other ways. The best stocks, however, excel in many different areas, which all come together to make up a very attractive picture.

Some of the most basic yet important things to look for in a stock are:

  • 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 don't mean anything if a company can't turn them into profits. Strong margins ensure a company is able to turn revenue into profit.
  • Balance sheet. Debt-laden companies have banks and bondholders competing with shareholders for management's attention. Companies with strong balance sheets don't have to worry about the distraction of debt.
  • Money-making opportunities. Companies need to be able to turn their resources into profitable business opportunities. Return on equity helps measure how well a company is finding those opportunities.
  • Valuation. You can't afford to pay too much for even the best companies. Earnings multiples are simple, but using normalized figures gives you a sense of how valuation fits into a longer-term context.
  • Dividends. Investors are demanding tangible proof of profits, and there's nothing more tangible than getting a check every three months. 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 Panera.

Panera scores five points on our 10-point scale. The breadmaker hasn't rewarded investors with a dividend yet, but it has shown strong growth despite the recession and has plenty of good prospects for the future.

Panera is one of the pioneers of the trend toward fast casual dining, aiming to offer better-tasting food than you'll find at fast-food restaurants while avoiding the fancy-restaurant atmosphere and its associated expense. By avoiding the real estate costs of freestanding buildings, Panera can offer startup costs to potential franchisees that are just over a quarter what McDonald's (NYSE: MCD) franchisees pay.

So far, that's been a very successful strategy. Like fellow fast-casual rival Chipotle Mexican Grill (NYSE: CMG), Panera cooked up some strong results in its most recent quarter, beating analyst expectations and raising guidance for the coming fiscal year. Last summer, a foray into the frozen drink arena did well for the company despite a push from McDonald's to go head-to-head against Starbucks (Nasdaq: SBUX).

Those investors looking for huge bargains won't necessarily be happy with either Panera's menu offerings or its shares, which carry a pricey valuation. But the company's ability to raise prices where fast-food competitors like Yum! Brands (NYSE: YUM) have faced big difficulty bodes well for the company's margins going forward.

With no dividend, Panera isn't the perfect stock. But with its core concept performing so well, Panera's worth a second look for those looking to get in on a growth opportunity.
