The excitement of investing in a company that can reverse its fortunes is a big draw for some speculators, so even companies that have no revenue, no profit, and a record of falling short, can manage to find investors. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Waste Management (NYSE:WM). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

How Quickly Is Waste Management Increasing Earnings Per Share?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. That makes EPS growth an attractive quality for any company. Impressively, Waste Management has grown EPS by 19% per year, compound, in the last three years. If the company can sustain that sort of growth, we'd expect shareholders to come away satisfied.

We note that their impressive stake in the company is worth US$152m. While that is a lot of skin in the game, we note this holding only totals to 0.2% of the business, which is a result of the company being so large.
