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 Wal-Mart (NYSE: WMT) 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 Wal-Mart.

With four points, Wal-Mart isn't ringing up perfection just yet. The discount retail giant has been a leader for decades, but the company has struggled recently.

During the recession, Wal-Mart's stock was a beacon of hope in a gloomy market. In 2008, when the S&P dropped 37%, Wal-Mart actually posted a big 20% gain -- even as similar retailers, like Target (NYSE: TGT), suffered significant share losses.

Yet now that the recession is supposedly over, Wal-Mart is facing almost unique difficulty in sustaining growth. Last month, the company announced its eighth straight quarter of falling same-store sales in its U.S. stores. International growth has been stronger, with an 11.5% gain in sales in the latest quarter. But at $28 billion per quarter, the international segment still represents only about a quarter of total revenue. Meanwhile, rival Costco (Nasdaq: COST), which would seem to have roughly the same target audience, has had very few problems, and BJ's Wholesale (NYSE: BJ) has also managed to beat a tough environment to post good results.

Part of the problem may be competition from below. Wal-Mart is no longer the cheapest game in town, with ultra-discounters Dollar General (NYSE: DG), Family Dollar (NYSE: FDO), and Big Lots (NYSE: BIG) offering even lower prices on some items.

Until Wal-Mart can regain its reputation as the undisputed low-price leader, its retreat from perfection will likely continue. Only by refocusing on its core mission will it restore its former greatness.
