Like a puppy chasing its tail, some new investors often chase 'the next big thing', even if that means buying 'story stocks' without revenue, let alone profit. 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 Antofagasta (LON:ANTO). 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 Antofagasta 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 means EPS growth is considered a real positive by most successful long-term investors. We can see that in the last three years Antofagasta grew its EPS by 16% per year. That's a pretty good rate, if the company can sustain it.

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. Antofagasta shareholders can take confidence from the fact that EBIT margins are up from 23% to 44%, and revenue is growing. Ticking those two boxes is a good sign of growth, in my book.

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 Antofagasta?

Are Antofagasta Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a UK£14b company like Antofagasta. But we are reassured by the fact they have invested in the company. Notably, they have an enormous stake in the company, worth US$599m. I would find that kind of skin in the game quite encouraging, if I owned shares, since it would ensure that the leaders of the company would also experience my success, or failure, with the stock.

Is Antofagasta Worth Keeping An Eye On?

One positive for Antofagasta is that it is growing EPS. That's nice to see. If that's not enough on its own, there is also the rather notable levels of insider ownership. The combination sparks joy for me, so I'd consider keeping the company on a watchlist. We should say that we've discovered 1 warning sign for Antofagasta that you should be aware of before investing here.
