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 Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.'

In the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Ball (NYSE:BLL). 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.

Ball's Earnings Per Share Are Growing.

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. As a tree reaches steadily for the sky, Ball's EPS has grown 24% 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. Ball maintained stable EBIT margins over the last year, all while growing revenue 5.6% to US$12b. That's a real positive.

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 Ball?

Are Ball Insiders Aligned With All Shareholders?

Since Ball has a market capitalization of US$30b, we wouldn't expect insiders to hold a large percentage of shares. But we are reassured by the fact they have invested in the company. Indeed, they have a glittering mountain of wealth invested in it, currently valued at US$198m. This suggests to me that leadership will be very mindful of shareholders' interests when making decisions!

Should You Add Ball To Your Watchlist?

Further, the high level of insider ownership impresses me, and suggests that I'm not the only one who appreciates the EPS growth. 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.
