The truth is that if you invest for long enough, you're going to end up with some losing stocks. But the long term shareholders of Hainan Development HoldingsNanhai Co., Ltd. (SZSE:002163) have had an unfortunate run in the last three years. So they might be feeling emotional about the 65% share price collapse, in that time. And the ride hasn't got any smoother in recent times over the last year, with the price 39% lower in that time. Furthermore, it's down 21% in about a quarter. That's not much fun for holders.

With the stock having lost 6.4% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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...' 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, Hainan Development HoldingsNanhai moved from a loss to profitability. We would usually expect to see the share price rise as a result. So it's worth looking at other metrics to try to understand the share price move.

With revenue flat over three years, it seems unlikely that the share price is reflecting the top line. There doesn't seem to be any clear correlation between the fundamental business metrics and the share price. That could mean that the stock was previously overrated, or it could spell opportunity now.

A Different Perspective

We regret to report that Hainan Development HoldingsNanhai shareholders are down 39% for the year. Unfortunately, that's worse than the broader market decline of 11%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 5%, 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.
