Shenzhen Refond Optoelectronics Co.,Ltd. (SZSE:300241) shareholders should be happy to see the share price up 21% in the last week. But that doesn't change the fact that the returns over the last three years have been less than pleasing. In fact, the share price is down 38% in the last three years, falling well short of the market return.

While the stock has risen 21% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

Shenzhen Refond OptoelectronicsLtd wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. When a company doesn't make profits, we'd generally expect to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Over three years, Shenzhen Refond OptoelectronicsLtd grew revenue at 1.5% per year. That's not a very high growth rate considering it doesn't make profits. The stock dropped 11% during that time. If revenue growth accelerates, we might see the share price bounce. But ultimately the key will be whether the company can become profitability.

A Different Perspective

While the broader market lost about 17% in the twelve months, Shenzhen Refond OptoelectronicsLtd 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 5% 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.
