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 SDI Group (LON:SDI). While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

How Fast Is SDI Group Growing?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS). Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. As a tree reaches steadily for the sky, SDI Group's EPS has grown 29% each year, compound, over three years. So it's not surprising to see the company trades on a very high multiple of (past) earnings.

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. SDI Group shareholders can take confidence from the fact that EBIT margins are up from 14% to 17%, and revenue is growing. That's great to see, on both counts.

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 SDI Group?

Are SDI Group Insiders Aligned With All Shareholders?

I always like to check up on CEO compensation, because I think that reasonable pay levels, around or below the median, can be a sign that shareholder interests are well considered. I discovered that the median total compensation for the CEOs of companies like SDI Group with market caps between UK£72m and UK£289m is about UK£411k.

The SDI Group CEO received UK£236k in compensation for the year ending . That comes in below the average for similar sized companies, and seems pretty reasonable to me. CEO remuneration levels are not the most important metric for investors, but when the pay is modest, that does support enhanced alignment between the CEO and the ordinary shareholders. It can also be a sign of a culture of integrity, in a broader sense.
