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.' Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

In contrast to all that, many investors prefer to focus on companies like Pearson (LON:PSON), which has not only revenues, but also profits. 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.

Generally, companies experiencing growth in earnings per share (EPS) should see similar trends in share price. That makes EPS growth an attractive quality for any company. Shareholders will be happy to know that Pearson's EPS has grown 21% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away satisfied.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. Pearson reported flat revenue and EBIT margins over the last year. While this doesn't ring alarm bells, it may not meet the expectations of growth-minded investors.
