While Crystal Clear Electronic Material Co.,Ltd (SZSE:300655) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 11% in the last quarter. But in stark contrast, the returns over the last half decade have impressed. Indeed, the share price is up an impressive 138% 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. Of course, that doesn't necessarily mean it's cheap now. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 40% decline over the last twelve months.

While the stock has fallen 4.3% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

Over half a decade, Crystal Clear Electronic MaterialLtd managed to grow its earnings per share at 0.4% a year. This EPS growth is slower than the share price growth of 19% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth. This optimism is visible in its fairly high P/E ratio of 106.36.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Crystal Clear Electronic MaterialLtd's TSR for the last 5 years was 144%, 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

While the broader market lost about 13% in the twelve months, Crystal Clear Electronic MaterialLtd shareholders did even worse, losing 40% (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. On the bright side, long term shareholders have made money, with a gain of 20% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
