1.0% earnings growth over 5 years has not materialized into gains for Jiangsu General Science Technology (SHSE:601500) shareholders over that period

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But the main game is to find enough winners to more than offset the losers So we wouldn't blame long term Jiangsu General Science Technology Co., Ltd. (SHSE:601500) shareholders for doubting their decision to hold, with the stock down 18% over a half decade. The share price has dropped 31% in three months.

Since Jiangsu General Science Technology has shed CN¥604m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

While the share price declined over five years, Jiangsu General Science Technology actually managed to increase EPS by an average of 5.0% per year. So it doesn't seem like EPS is a great guide to understanding how the market is valuing the stock. Or possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

Generally speaking we'd hope to see stronger share price increases on the back of sustained EPS growth, but other metrics may hold a clue to why the share price performance is relatively modest.

We don't think that the 1.3% is big factor in the share price, since it's quite small, as dividends go. In contrast to the share price, revenue has actually increased by 8.3% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Jiangsu General Science Technology, it has a TSR of -12% 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

It's good to see that Jiangsu General Science Technology has rewarded shareholders with a total shareholder return of 3.3% in the last twelve months. Of course, that includes the dividend. That certainly beats the loss of about 2% per year over the last half decade. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. 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.
