Guangdong Dongfang Precision Science & Technology Co., Ltd. (SZSE:002611) shareholders might be concerned after seeing the share price drop 12% in the last month. On the bright side the returns have been quite good over the last half decade. After all, the share price is up a market-beating 28% in that time.

Although Guangdong Dongfang Precision Science & Technology has shed CN¥467m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last half decade, Guangdong Dongfang Precision Science & Technology became profitable. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price.

A Different Perspective

It's good to see that Guangdong Dongfang Precision Science & Technology has rewarded shareholders with a total shareholder return of 5.1% in the last twelve months. Since the one-year TSR is better than the five-year TSR (the latter coming in at 5% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Guangdong Dongfang Precision Science & Technology you should know about.
