Some have more dollars than sense, they say, so even companies that have no revenue, no profit, and a record of falling short, can easily find investors. But as Warren Buffett has mused, 'If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy.' When they buy such story stocks, investors are all too often the patsy.

In contrast to all that, I prefer to spend time on companies like Arcontech Group (LON:ARC), which has not only revenues, but also profits. While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. Loss-making companies are always racing against time to reach financial sustainability, but time is often a friend of the profitable company, especially if it is growing.

How Fast Is Arcontech Group Growing?

The market is a voting machine in the short term, but a weighing machine in the long term, so share price follows earnings per share (EPS) eventually. That makes EPS growth an attractive quality for any company. It certainly is nice to see that Arcontech Group has managed to grow EPS by 33% per year over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.

I like to take a look at earnings before interest and (EBIT) tax margins, as well as revenue growth, to get another take on the quality of the company's growth. Arcontech Group shareholders can take confidence from the fact that EBIT margins are up from 16% to 29%, and revenue is growing. That's great to see, on both counts.

In the chart below, you can see how the company has grown earnings, and revenue, over time. To see the actual numbers, click on the chart.

Since Arcontech Group is no giant, with a market capitalization of UK£23m, so you should definitely check its cash and debt before getting too excited about its prospects.

Are Arcontech Group Insiders Aligned With All Shareholders?

Many consider high insider ownership to be a strong sign of alignment between the leaders of a company and the ordinary shareholders. So as you can imagine, the fact that Arcontech Group insiders own a significant number of shares certainly appeals to me. In fact, they own 57% of the company, so they will share in the same delights and challenges experienced by the ordinary shareholders. To me this is a good sign because it suggests they will be incentivised to build value for shareholders over the long term. In terms of absolute value, insiders have UK£13m invested in the business, using the current share price. That's nothing to sneeze at!

Should You Add Arcontech Group To Your Watchlist?

You can't deny that Arcontech Group has grown its earnings per share at a very impressive rate. That's attractive. I think that EPS growth is something to boast of, and it doesn't surprise me that insiders are holding on to a considerable chunk of shares. So this is very likely the kind of business that I like to spend time researching, with a view to discerning its true value. While we've looked at the quality of the earnings, we haven't yet done any work to value the stock. So if you like to buy cheap, you may want to check if Arcontech Group is trading on a high P/E or a low P/E, relative to its industry.

Of course, you can do well (sometimes) buying stocks that are not growing earnings and do not have insiders buying shares. But as a growth investor I always like to check out companies that do have those features. You can access a free list of them here.
