Shanghai Prosolar Resources Development Co., Ltd (SHSE:600193) shareholders should be happy to see the share price up 24% in the last quarter. But that cannot eclipse the less-than-impressive returns over the last three years. After all, the share price is down 49% in the last three years, significantly under-performing the market.

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

Shanghai Prosolar Resources Development isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. When a company doesn't make profits, we'd generally hope to see good revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

In the last three years Shanghai Prosolar Resources Development saw its revenue shrink by 78% per year. That means its revenue trend is very weak compared to other loss making companies. With revenue in decline, the share price decline of 14% per year is hardly undeserved. It would probably be worth asking whether the company can fund itself to profitability. Of course, it is possible for businesses to bounce back from a revenue drop - but we'd want to see that before getting interested.

A Different Perspective

Investors in Shanghai Prosolar Resources Development had a tough year, with a total loss of 35%, against a market gain of about 11%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 3% 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.
