It's only natural that many investors, especially those who are new to the game, prefer to buy shares in 'sexy' stocks with a good story, even if those businesses lose money. 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.

So if you're like me, you might be more interested in profitable, growing companies, like Rubis (EPA:RUI). Even if the shares are fully valued today, most capitalists would recognize its profits as the demonstration of steady value generation. 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.

Rubis's Earnings Per Share Are Growing.

As one of my mentors once told me, share price follows earnings per share (EPS). That makes EPS growth an attractive quality for any company. We can see that in the last three years Rubis grew its EPS by 8.7% per year. That's a pretty good rate, if the company can sustain it.

I like to see top-line growth as an indication that growth is sustainable, and I look for a high earnings before interest and taxation (EBIT) margin to point to a competitive moat (though some companies with low margins also have moats). Rubis maintained stable EBIT margins over the last year, all while growing revenue 12% to €5.1b. That's progress.

While we live in the present moment at all times, there's no doubt in my mind that the future matters more than the past. So why not check this interactive chart depicting future EPS estimates, for Rubis?

Are Rubis Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a €5.4b company like Rubis. But we do take comfort from the fact that they are investors in the company. To be specific, they have €14m worth of shares. That shows significant buy-in, and may indicate conviction in the business strategy. Despite being just 0.3% of the company, the value of that investment is enough to show insiders have plenty riding on the venture.

Should You Add Rubis To Your Watchlist?

One positive for Rubis is that it is growing EPS. That's nice to see. Just as polish makes silverware pop, the high level of insider ownership enhances my enthusiasm for this growth. That combination appeals to me, for one. So yes, I do think the stock is worth keeping an eye on. Of course, identifying quality businesses is only half the battle; investors need to know whether the stock is undervalued.
