Is Now The Time To Put Tenaris (BIT:TEN) On Your Watchlist?

For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it completely lacks a track record of revenue and profit. 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 the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Tenaris (BIT:TEN). 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 Tenaris 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. That makes EPS growth an attractive quality for any company. As a tree reaches steadily for the sky, Tenaris's EPS has grown 19% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.

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. Tenaris shareholders can take confidence from the fact that EBIT margins are up from 0.5% to 15%, and revenue is growing. That's great to see, on both counts.

In the chart below, you can see how the company has grown earnings, and revenue, over time. To see the actual numbers, click on the chart.

Are Tenaris Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a €17b company like Tenaris. But we do take comfort from the fact that they are investors in the company. To be specific, they have US$14m worth of shares. That shows significant buy-in, and may indicate conviction in the business strategy. Despite being just 0.08% of the company, the value of that investment is enough to show insiders have plenty riding on the venture.

Is Tenaris Worth Keeping An Eye On?

You can't deny that Tenaris has grown its earnings per share at a very impressive rate. That's attractive. 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. So this is very likely the kind of business that I like to spend time researching, with a view to discerning its true value. However, before you get too excited we've discovered 3 warning signs for Tenaris (1 is potentially serious!) that you should be aware of.
