It's easy to match the overall market return by buying an index fund. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. Investors in Hubei Jiuzhiyang Infrared System Co., Ltd (SZSE:300516) have tasted that bitter downside in the last year, as the share price dropped 21%. That's disappointing when you consider the market declined 16%. Even if shareholders bought some time ago, they wouldn't be particularly happy: the stock is down 19% in three years. On top of that, the share price is down 7.8% in the last week. However, this move may have been influenced by the broader market, which fell 4.7% in that time.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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

During the unfortunate twelve months during which the Hubei Jiuzhiyang Infrared System share price fell, it actually saw its earnings per share (EPS) improve by 5.5%. It's quite possible that growth expectations may have been unreasonable in the past.

It's surprising to see the share price fall so much, despite the improved EPS. So it's well worth checking out some other metrics, too.

Given the yield is quite low, at 1.3%, we doubt the dividend can shed much light on the share price. Hubei Jiuzhiyang Infrared System's revenue is actually up 4.8% 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 16% in the twelve months, Hubei Jiuzhiyang Infrared System shareholders did even worse, losing 20% (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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 1.7% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
