It might be of some concern to shareholders to see the Dalian Thermal Power Co.,Ltd. (SHSE:600719) share price down 21% in the last month. But in three years the returns have been great. In fact, the share price is up a full 142% compared to three years ago. It's not uncommon to see a share price retrace a bit, after a big gain. If the business can perform well for years to come, then the recent drop could be an opportunity.

In light of the stock dropping 10% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive three-year return.

A Different Perspective

The total return of 15% received by Dalian Thermal PowerLtd shareholders over the last year isn't far from the market return of -17%. Longer term investors wouldn't be so upset, since they would have made 10%, each year, over five years. If the stock price has been impacted by changing sentiment, rather than deteriorating business conditions, it could spell opportunity. 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.
