Do Mainfreight's (NZSE:MFT) Earnings Warrant Your Attention?

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.'

So if you're like me, you might be more interested in profitable, growing companies, like Mainfreight (NZSE:MFT). 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. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

Mainfreight's Earnings Per Share Are Growing.

As one of my mentors once told me, share price follows earnings per share (EPS). Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. It certainly is nice to see that Mainfreight has managed to grow EPS by 27% per year 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.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. Mainfreight maintained stable EBIT margins over the last year, all while growing revenue 31% to NZ$4.2b. That's a real positive.

Of course the knack is to find stocks that have their best days in the future, not in the past. You could base your opinion on past performance, of course, but you may also want to check this interactive graph of professional analyst EPS forecasts for Mainfreight.

Are Mainfreight Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a NZ$8.5b company like Mainfreight. But we do take comfort from the fact that they are investors in the company. Notably, they have an enormous stake in the company, worth NZ$1.6b. That equates to 18% of the company, making insiders powerful and aligned with other shareholders. So it might be my imagination, but I do sense the glimmer of an opportunity.

Should You Add Mainfreight To Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Mainfreight'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. Of course, just because Mainfreight is growing does not mean it is undervalued.

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.
