Sino Geophysical (SZSE:300191 investor three-year losses grow to 27% as the stock sheds CN¥403m this past week

While it may not be enough for some shareholders, we think it is good to see the Sino Geophysical Co., Ltd (SZSE:300191) share price up 17% in a single quarter. But that doesn't help the fact that the three year return is less impressive. After all, the share price is down 27% in the last three years, significantly under-performing the market.

With the stock having lost 8.4% 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 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.

Over the three years that the share price declined, Sino Geophysical's earnings per share (EPS) dropped significantly, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

A Different Perspective

We regret to report that Sino Geophysical shareholders are down 23% for the year. Unfortunately, that's worse than the broader market decline of 10%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 4% over the last half decade. 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.
