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. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.'

If, on the other hand, you like companies that have revenue, and even earn profits, then you may well be interested in Sierra Metals (TSE:SMT). 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.

Sierra Metals's Earnings Per Share Are 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. Impressively, Sierra Metals has grown EPS by 35% per year, compound, in the last three years. As a general rule, we'd say that if a company can keep up that sort of growth, shareholders will be smiling.

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. Sierra Metals shareholders can take confidence from the fact that EBIT margins are up from 11% to 28%, and revenue is growing. That's great to see, on both counts.

Are Sierra Metals Insiders Aligned With All Shareholders?

It makes me feel more secure owning shares in a company if insiders also own shares, thusly more closely aligning our interests. So it is good to see that Sierra Metals insiders have a significant amount of capital invested in the stock. Indeed, they hold US$31m worth of its stock. That's a lot of money, and no small incentive to work hard. That amounts to 7.2% of the company, demonstrating a degree of high-level alignment with shareholders.

Does Sierra Metals Deserve A Spot On Your Watchlist?

For growth investors like me, Sierra Metals's raw rate of earnings growth is a beacon in the night. Further, the high level of insider ownership impresses me, and suggests that I'm not the only one who appreciates the EPS growth. So this is very likely the kind of business that I like to spend time researching, with a view to discerning its true value. What about risks? Every company has them, and we've spotted 1 warning sign for Sierra Metals you should know about.
