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 completely lacks a track record of revenue and profit. And in their study titled Who Falls Prey to the Wolf of Wall Street?' Leuz et. al. found that it is 'quite common' for investors to lose money by buying into 'pump and dump' schemes.

In contrast to all that, I prefer to spend time on companies like SigmaRoc (LON:SRC), which has not only revenues, but also profits. Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Fast Is SigmaRoc Growing Its Earnings Per Share?

In the last three years SigmaRoc's earnings per share took off like a rocket; fast, and from a low base. So the actual rate of growth doesn't tell us much. Thus, it makes sense to focus on more recent growth rates, instead. Like the last firework on New Year's Eve accelerating into the sky, SigmaRoc's EPS shot from UK£0.0092 to UK£0.025, over the last year. You don't see 177% year-on-year growth like that, very often. That could be a sign that the business has reached a true inflection point.

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. SigmaRoc maintained stable EBIT margins over the last year, all while growing revenue 76% to UK£124m. That's a real positive.

Are SigmaRoc Insiders Aligned With All Shareholders?

Like that fresh smell in the air when the rains are coming, insider buying fills me with optimistic anticipation. This view is based on the possibility that stock purchases signal bullishness on behalf of the buyer. Of course, we can never be sure what insiders are thinking, we can only judge their actions.

In the last twelve months SigmaRoc insiders spent UK£32k on stock; good news for shareholders. This might not be a huge sum, but it's well worth noting anyway, given the complete lack of selling.

On top of the insider buying, it's good to see that SigmaRoc insiders have a valuable investment in the business. Indeed, they hold UK£27m worth of its stock. That shows significant buy-in, and may indicate conviction in the business strategy. Those holdings account for over 11% of the company; visible skin in the game.
