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.

In the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Insight Enterprises (NASDAQ:NSIT). Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. 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 Insight Enterprises Growing?

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, Insight Enterprises's EPS has grown 25% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.

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. Insight Enterprises maintained stable EBIT margins over the last year, all while growing revenue 7.8% to US$8.3b. That's a real positive.

It makes me feel more secure owning shares in a company if insiders also own shares, thusly more closely aligning our interests.

With a whopping US$55m worth of shares as a group, insiders have plenty riding on the company's success. That's certainly enough to make me think that management will be very focussed on long term growth.
