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 the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Sungrow Power Supply (SZSE:300274). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

How Fast Is Sungrow Power Supply Growing Its Earnings Per Share?

In business, profits are a key measure of success; and share prices tend to reflect earnings per share (EPS) performance. So a growing EPS generally brings attention to a company in the eyes of prospective investors. It is awe-striking that Sungrow Power Supply's EPS went from CN¥1.44 to CN¥5.92 in just one year. Even though that growth rate may not be repeated, that looks like a breakout improvement. This could point to the business hitting a point of inflection.

Top-line growth is a great indicator that growth is sustainable, and combined with a high earnings before interest and taxation (EBIT) margin, it's a great way for a company to maintain a competitive advantage in the market. Sungrow Power Supply shareholders can take confidence from the fact that EBIT margins are up from 5.8% to 16%, and revenue is growing.
