Guangdong Ganhua Science & Industry Co.,Ltd. (SZSE:000576) shareholders should be happy to see the share price up 16% in the last month. But that cannot eclipse the less-than-impressive returns over the last three years. In fact, the share price is down 49% in the last three years, falling well short of the market return.

While the stock has risen 15% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Guangdong Ganhua Science & IndustryLtd saw its share price decline over the three years in which its EPS also dropped, falling to a loss. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

A Different Perspective

While the broader market lost about 10% in the twelve months, Guangdong Ganhua Science & IndustryLtd shareholders did even worse, losing 36%. 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 4% 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.
