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.

So if you're like me, you might be more interested in profitable, growing companies, like Allied Motion Technologies (NASDAQ:AMOT). Even if the shares are fully valued today, most capitalists would recognize its profits as the demonstration of steady value generation. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Quickly Is Allied Motion Technologies Increasing Earnings Per Share?

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). That means EPS growth is considered a real positive by most successful long-term investors. Impressively, Allied Motion Technologies has grown EPS by 29% 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. Allied Motion Technologies reported flat revenue and EBIT margins over the last year. That's not a major concern but nor does it point to the long term growth we like to see.

Are Allied Motion Technologies Insiders Aligned With All Shareholders?

I like company leaders to have some skin in the game, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. So it is good to see that Allied Motion Technologies insiders have a significant amount of capital invested in the stock. Given insiders own a small fortune of shares, currently valued at US$94m, they have plenty of motivation to push the business to succeed. That holding amounts to 18% of the stock on issue, thus making insiders influential, and aligned, owners of the business.

Is Allied Motion Technologies Worth Keeping An Eye On?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Allied Motion Technologies's strong EPS growth. 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. It's still necessary to consider the ever-present spectre of investment risk.
