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. Unfortunately, high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson.

In the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Antofagasta (LON:ANTO). 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 Antofagasta Growing?

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. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Antofagasta managed to grow EPS by 16% per year, over three years. That's a good rate of growth, if it can be sustained.

I like to see top-line growth as an indication that growth is sustainable, and I look for a high earnings before interest and taxation (EBIT) margin to point to a competitive moat (though some companies with low margins also have moats). The good news is that Antofagasta is growing revenues, and EBIT margins improved by 21.4 percentage points to 44%, over the last year. That's great to see, on both counts.

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£12b company like Antofagasta. 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$515m. 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?

As I already mentioned, Antofagasta is a growing business, which is what I like to see. Just as polish makes silverware pop, the high level of insider ownership enhances my enthusiasm for this growth. The combination sparks joy for me, so I'd consider keeping the company on a watchlist. We don't want to rain on the parade too much, but we did also find 1 warning sign for Antofagasta that you need to be mindful of.

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.
