Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. Investors in Shanghai Wondertek Software Co., Ltd (SHSE:603189) have tasted that bitter downside in the last year, as the share price dropped 32%. That falls noticeably short of the market decline of around 15%. However, the longer term returns haven't been so bad, with the stock down 21% in the last three years. Shareholders have had an even rougher run lately, with the share price down 26% in the last 90 days.

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

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the last year Shanghai Wondertek Software saw its earnings per share drop below zero. While this may prove temporary, we'd consider it a negative, so it doesn't surprise us that the stock price is down. However, there may be an opportunity for investors if the company can recover.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

A Different Perspective

While the broader market lost about 15% in the twelve months, Shanghai Wondertek Software shareholders did even worse, losing 31% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. 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. Take risks, for example - Shanghai Wondertek Software has 2 warning signs (and 1 which can't be ignored) we think you should know about.
