Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. That downside risk was realized by Dirui Industrial Co.,Ltd. (SZSE:300396) shareholders over the last year, as the share price declined 29%. That contrasts poorly with the market decline of 20%. At least the damage isn't so bad if you look at the last three years, since the stock is down 11% in that time. In the last ninety days we've seen the share price slide 35%.

On a more encouraging note the company has added CN¥374m to its market cap in just the last 7 days, so let's see if we can determine what's driven the one-year loss for shareholders.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Even though the Dirui IndustrialLtd share price is down over the year, its EPS actually improved. Of course, the situation might betray previous over-optimism about growth.

It's surprising to see the share price fall so much, despite the improved EPS. So it's easy to justify a look at some other metrics.

Dirui IndustrialLtd's revenue is actually up 29% over the last year. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

While the broader market lost about 20% in the twelve months, Dirui IndustrialLtd shareholders did even worse, losing 27% (even including dividends). 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 3%, 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider risks, for instance.
