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. Unfortunately, high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson.

In contrast to all that, I prefer to spend time on companies like Service Stream (ASX:SSM), which has not only revenues, but also profits. While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. While a well funded company may sustain losses for years, unless its owners have an endless appetite for subsidizing the customer, it will need to generate a profit eventually, or else breathe its last breath.

How Quickly Is Service Stream Increasing Earnings Per Share?

The market is a voting machine in the short term, but a weighing machine in the long term, so share price follows earnings per share (EPS) eventually. That means EPS growth is considered a real positive by most successful long-term investors. As a tree reaches steadily for the sky, Service Stream's EPS has grown 28% each year, compound, over 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. Service Stream maintained stable EBIT margins over the last year, all while growing revenue 46% to AU$1.0b. That's a real positive.

Are Service Stream 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 Service Stream shares worth a considerable sum. Given insiders own a small fortune of shares, currently valued at AU$126m, they have plenty of motivation to push the business to succeed. At 15% of the company, the co-investment by insiders gives me confidence that management will make long-term focussed decisions.

Should You Add Service Stream To Your Watchlist?

For growth investors like me, Service Stream's raw rate of earnings growth is a beacon in the night. I think that EPS growth is something to boast of, and it doesn't surprise me that insiders are holding on to a considerable chunk of shares. 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. However, before you get too excited we've discovered 2 warning signs for Service Stream that you should be aware of.

Although Service Stream 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.
