For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Eastman Chemical (NYSE:EMN). 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 Eastman Chemical 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. Recognition must be given to the that Eastman Chemical has grown EPS by 47% per year, over the last three years. Growth that fast may well be fleeting, but it should be more than enough to pique the interest of the wary stock pickers.

Top-line growth is a great indicator that growth is sustainable, and combined with a high earnings before interest and taxation (EBIT) margin, it's a great way for a company to maintain a competitive advantage in the market. Despite consistency in EBIT margins year on year, Eastman Chemical has actually recorded a dip in revenue. Suffice it to say that is not a great sign of growth.
