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 currently lacks a track record of revenue and profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Sieyuan Electric (SZSE:002028). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Fast Is Sieyuan Electric Growing?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. So it makes sense that experienced investors pay close attention to company EPS when undertaking investment research. It certainly is nice to see that Sieyuan Electric has managed to grow EPS by 18% per year over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

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. The music to the ears of Sieyuan Electric shareholders is that EBIT margins have grown from 13% to 15% in the last 12 months and revenues are on an upwards trend as well. That's great to see, on both counts.

Are Sieyuan Electric Insiders Aligned With All Shareholders?

Since Sieyuan Electric has a market capitalisation of CN¥51b, we wouldn't expect insiders to hold a large percentage of shares. But we are reassured by the fact they have invested in the company. Notably, they have an enviable stake in the company, worth CN¥18b. That equates to 35% of the company, making insiders powerful and aligned with other shareholders. Very encouraging.

Should You Add Sieyuan Electric To Your Watchlist?

If you believe that share price follows earnings per share you should definitely be delving further into Sieyuan Electric's strong EPS growth. This EPS growth rate is something the company should be proud of, and so it's no surprise that insiders are holding on to a considerable chunk of shares. The growth and insider confidence is looked upon well and so it's worthwhile to investigate further with a view to discern the stock's true value. Of course, just because Sieyuan Electric is growing does not mean it is undervalued.

There's always the possibility of doing well buying stocks that are not growing earnings and do not have insiders buying shares. But for those who consider these important metrics, we encourage you to check out companies that do have those features.
