Some have more dollars than sense, they say, so even companies that have no revenue, no profit, and a record of falling short, can easily find investors. 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 the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Aurizon Holdings (ASX:AZJ). 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 Quickly Is Aurizon Holdings Increasing Earnings Per Share?

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. Over the last three years, Aurizon Holdings has grown EPS by 8.5% per year. That growth rate is fairly good, assuming the company can keep it up.

I like to take a look at earnings before interest and (EBIT) tax margins, as well as revenue growth, to get another take on the quality of the company's growth. It seems Aurizon Holdings is pretty stable, since revenue and EBIT margins are pretty flat year on year. That's not a major concern but nor does it point to the long term growth we like to see.

Are Aurizon Holdings Insiders Aligned With All Shareholders?

Like standing at the lookout, surveying the horizon at sunrise, insider buying, for some investors, sparks joy. This view is based on the possibility that stock purchases signal bullishness on behalf of the buyer. However, small purchases are not always indicative of conviction, and insiders don't always get it right.

The good news is that Aurizon Holdings insiders spent a whopping AU$3.9m on stock in just one year, and I didn't see any selling. And so I find myself almost expectant, and certainly hopeful, that this large outlay signals prescient optimism for the business. We also note that it was the MD, CEO & Director, Andrew Harding, who made the biggest single acquisition, paying AU$3.4m for shares at about AU$3.43 each.
