Zhejiang Sanhua Intelligent Controls Co.,Ltd (SZSE:002050) shareholders might be concerned after seeing the share price drop 21% in the last quarter. But that doesn't change the fact that the returns over the last five years have been very strong. Indeed, the share price is up an impressive 125% in that time. So while it's never fun to see a share price fall, it's important to look at a longer time horizon. Ultimately business performance will determine whether the stock price continues the positive long term trend. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 37% decline over the last twelve months.

While the stock has fallen 12% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, Zhejiang Sanhua Intelligent ControlsLtd managed to grow its earnings per share at 17% a year. That makes the EPS growth particularly close to the yearly share price growth of 18%. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Zhejiang Sanhua Intelligent ControlsLtd's TSR for the last 5 years was 138%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 16% in the twelve months, Zhejiang Sanhua Intelligent ControlsLtd shareholders did even worse, losing 36% (even including dividends). 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. Longer term investors wouldn't be so upset, since they would have made 19%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
