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 So we wouldn't blame long term Jiangsu Sanfame Polyester Material Co.,Ltd. (SHSE:600370) shareholders for doubting their decision to hold, with the stock down 24% over a half decade. The falls have accelerated recently, with the share price down 14% in the last three months. But this could be related to the weak market, which is down 6.4% in the same period.

If the past week is anything to go by, investor sentiment for Jiangsu Sanfame Polyester MaterialLtd isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the unfortunate half decade during which the share price slipped, Jiangsu Sanfame Polyester MaterialLtd actually saw its earnings per share (EPS) improve by 33% 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.

Due to the lack of correlation between the EPS growth and the falling share price, it's worth taking a look at other metrics to try to understand the share price movement.

The steady dividend doesn't really explain why the share price is down. It's not immediately clear to us why the stock price is down but further research might provide some answers.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. As it happens, Jiangsu Sanfame Polyester MaterialLtd's TSR for the last 5 years was -15%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Although it hurts that Jiangsu Sanfame Polyester MaterialLtd returned a loss of 12% in the last twelve months, the broader market was actually worse, returning a loss of 16%. Given the total loss of 3% per year over five years, it seems returns have deteriorated in the last twelve months. Whilst Baron Rothschild does tell the investor "buy when there's blood in the streets, even if the blood is your own", buyers would need to examine the data carefully to be comfortable that the business itself is sound. 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.
