When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Sichuan New Energy Power Company Limited (SZSE:000155) share price has soared 171% in the last half decade. Most would be very happy with that.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Sichuan New Energy Power achieved compound earnings per share (EPS) growth of 11% per year. This EPS growth is slower than the share price growth of 22% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. It might be well worthwhile taking a look at our free report on Sichuan New Energy Power's earnings, revenue and cash flow.

A Different Perspective

We regret to report that Sichuan New Energy Power shareholders are down 24% for the year. Unfortunately, that's worse than the broader market decline of 16%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 22% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand Sichuan New Energy Power better, we need to consider many other factors.
