Some Sichuan Em Technology Co., Ltd. (SHSE:601208) shareholders are probably rather concerned to see the share price fall 34% over the last three months. But that scarcely detracts from the really solid long term returns generated by the company over five years. In fact, the share price is 108% higher today. We think it's more important to dwell on the long term returns than the short term returns. Only time will tell if there is still too much optimism currently reflected in the share price.

Although Sichuan Em Technology has shed CN¥627m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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).

During five years of share price growth, Sichuan Em Technology achieved compound earnings per share (EPS) growth of 59% per year. The EPS growth is more impressive than the yearly share price gain of 16% over the same period. So it seems the market isn't so enthusiastic about the stock these days.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Sichuan Em Technology, it has a TSR of 118% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that Sichuan Em Technology shareholders are down 31% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 12%. 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 17%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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 for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Sichuan Em Technology (at least 1 which is a bit concerning) , and understanding them should be part of your investment process.
