Here's Why We Think ACI Worldwide (NASDAQ:ACIW) Is Well Worth Watching

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 as Warren Buffett has mused, 'If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy.' When they buy such story stocks, investors are all too often the patsy.

In contrast to all that, I prefer to spend time on companies like ACI Worldwide (NASDAQ:ACIW), 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 Fast Is ACI Worldwide Growing Its Earnings Per Share?

Over the last three years, ACI Worldwide has grown earnings per share (EPS) like young bamboo after rain; fast, and from a low base. So I don't think the percent growth rate is particularly meaningful. Thus, it makes sense to focus on more recent growth rates, instead. Like a falcon taking flight, ACI Worldwide's EPS soared from US$0.53 to US$0.73, over the last year. That's a impressive gain of 38%.

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. It seems ACI Worldwide is pretty stable, since revenue and EBIT margins are pretty flat year on year. That's not bad, but it doesn't point to ongoing future growth, either.

While we live in the present moment at all times, there's no doubt in my mind that the future matters more than the past. So why not check this interactive chart depicting future EPS estimates, for ACI Worldwide?

Are ACI Worldwide 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 ACI Worldwide insiders have a significant amount of capital invested in the stock. Indeed, they hold US$46m worth of its stock. That's a lot of money, and no small incentive to work hard. Even though that's only about 1.2% of the company, it's enough money to indicate alignment between the leaders of the business and ordinary shareholders.

Does ACI Worldwide Deserve A Spot On Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about ACI Worldwide's strong EPS growth. 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.
