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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

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 Vulcan Materials (NYSE:VMC). 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 Vulcan Materials Increasing Earnings Per Share?

That makes EPS growth an attractive quality for any company. Impressively, Vulcan Materials has grown EPS by 17% 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.
