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 contrast to all that, I prefer to spend time on companies like Sanmina (NASDAQ:SANM), which has not only revenues, but also profits. 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. Loss-making companies are always racing against time to reach financial sustainability, but time is often a friend of the profitable company, especially if it is growing.

How Fast Is Sanmina Growing Its Earnings Per Share?

Over the last three years, Sanmina has grown earnings per share (EPS) like young bamboo after rain; fast, and from a low base. So I don't think the percent growth rate is particularly meaningful. As a result, I'll zoom in on growth over the last year, instead. Like a firecracker arcing through the night sky, Sanmina's EPS shot from US$1.58 to US$4.06, over the last year. Year on year growth of 157% is certainly a sight to behold.

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 Sanmina 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.

In the chart below, you can see how the company has grown earnings, and revenue, over time. For finer detail, click on the image.

The trick, as an investor, is to find companies that are going to perform well in the future, not just in the past. To that end, right now and today, you can check our visualization of consensus analyst forecasts for future Sanmina EPS 100% free.

Are Sanmina Insiders Aligned With All Shareholders?

I like company leaders to have some skin in the game, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. As a result, I'm encouraged by the fact that insiders own Sanmina shares worth a considerable sum. With a whopping US$57m worth of shares as a group, insiders have plenty riding on the company's success. That's certainly enough to make me think that management will be very focussed on long term growth.

Is Sanmina Worth Keeping An Eye On?

Sanmina's earnings have taken off like any random crypto-currency did, back in 2017. That EPS growth certainly has my attention, and the large insider ownership only serves to further stoke my interest. At times fast EPS growth is a sign the business has reached an inflection point; and I do like those. So yes, on this short analysis I do think it's worth considering Sanmina for a spot on your watchlist. Don't forget that there may still be risks.
