Hangjin Technology Co., Ltd. (SZSE:000818) shareholders might be concerned after seeing the share price drop 28% in the last quarter. But that doesn't change the fact that shareholders have received really good returns over the last five years. In fact, the share price is 158% higher today. To some, the recent pullback wouldn't be surprising after such a fast rise. 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 39% decline over the last twelve months.

Since the stock has added CN¥528m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

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.

Hangjin Technology's earnings per share are down 19% per year, despite strong share price performance over five years.

Essentially, it doesn't seem likely that investors are focused on EPS. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

The modest 0.2% dividend yield is unlikely to be propping up the share price. The revenue growth of 2.8% per year hardly seems impressive. So it seems one might have to take closer look at earnings and revenue trends to see how they might influence the share price.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Hangjin Technology the TSR over the last 5 years was 163%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 18% in the twelve months, Hangjin Technology shareholders did even worse, losing 39% (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 21% 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. 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.
