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.'

So if you're like me, you might be more interested in profitable, growing companies, like Biotage (STO:BIOT). 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 Fast Is Biotage 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). That means EPS growth is considered a real positive by most successful long-term investors. Impressively, Biotage has grown EPS by 27% 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.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. Biotage maintained stable EBIT margins over the last year, all while growing revenue 21% to kr1.0b. That's a real positive.

In the chart below, you can see how the company has grown earnings, and revenue, over time. Click on the chart to see the exact numbers.

While it's always good to see growing profits, you should always remember that a weak balance sheet could come back to bite. So check Biotage's balance sheet strength, before getting too excited.

Are Biotage 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. As a result, I'm encouraged by the fact that insiders own Biotage shares worth a considerable sum. To be specific, they have kr312m worth of shares. That's a lot of money, and no small incentive to work hard. Even though that's only about 3.8% of the company, it's enough money to indicate alignment between the leaders of the business and ordinary shareholders.

Does Biotage Deserve A Spot On Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Biotage'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. Fast growth and confident insiders should be enough to warrant further research. So the answer is that I do think this is a good stock to follow along with. Now, you could try to make up your mind on Biotage by focusing on just these factors, or you could also consider how its price-to-earnings ratio compares to other companies in its industry.

Although Biotage certainly looks good to me, I would like it more if insiders were buying up shares. If you like to see insider buying, too, then this free list of growing companies that insiders are buying, could be exactly what you're looking for.
