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. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses.

If, on the other hand, you like companies that have revenue, and even earn profits, then you may well be interested in Hackett Group (NASDAQ:HCKT). 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. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

How Quickly Is Hackett Group 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 makes EPS growth an attractive quality for any company. As a tree reaches steadily for the sky, Hackett Group's EPS has grown 22% 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. Hackett Group reported flat revenue and EBIT margins over the last year. That's not bad, but it doesn't point to ongoing future growth, either.

Of course the knack is to find stocks that have their best days in the future, not in the past. You could base your opinion on past performance, of course, but you may also want to check this interactive graph of professional analyst EPS forecasts for Hackett Group.

Are Hackett Group 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 Hackett Group shares worth a considerable sum. Indeed, they hold US$48m worth of its stock. That's a lot of money, and no small incentive to work hard. Those holdings account for over 10.0% of the company; visible skin in the game.

Should You Add Hackett Group To Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Hackett Group's strong EPS growth. Further, the high level of insider buying 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. While we've looked at the quality of the earnings, we haven't yet done any work to value the stock. So if you like to buy cheap, you may want to check if Hackett Group is trading on a high P/E or a low P/E, relative to its industry.

Of course, you can do well (sometimes) buying stocks that are not growing earnings and do not have insiders buying shares. But as a growth investor I always like to check out companies that do have those features. You can access a free list of them here.
