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 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 Protec (KOSDAQ:053610), 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.

Protec's Earnings Per Share Are Growing

The market is a voting machine in the short term, but a weighing machine in the long term, so you'd expect share price to follow earnings per share (EPS) outcomes eventually. That means EPS growth is considered a real positive by most successful long-term investors. Protec's shareholders have have plenty to be happy about as their annual EPS growth for the last 3 years was 52%. That sort of growth rarely ever lasts long, but it is well worth paying attention to when it happens.

It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. The music to the ears of Protec shareholders is that EBIT margins have grown from 10% to 25% in the last 12 months and revenues are on an upwards trend as well. That's great to see, on both counts.
