For many, the main point of investing is to generate higher returns than the overall market. But the main game is to find enough winners to more than offset the losers At this point some shareholders may be questioning their investment in China CAMC Engineering Co., Ltd. (SZSE:002051), since the last five years saw the share price fall 39%. And some of the more recent buyers are probably worried, too, with the stock falling 36% in the last year.

With the stock having lost 4.2% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, China CAMC Engineering moved from a loss to profitability. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

We don't think that the 1.8% is big factor in the share price, since it's quite small, as dividends go. Revenue is actually up 3.1% over the time period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

It is of course excellent to see how China CAMC Engineering has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at China CAMC Engineering's financial health with this free report on its balance sheet.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of China CAMC Engineering, it has a TSR of -35% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market lost about 17% in the twelve months, China CAMC Engineering shareholders did even worse, losing 35% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 6% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
