Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. Buying under-rated businesses is one path to excess returns. For example, long term Suzhou Chunxing Precision Mechanical Co., Ltd. (SZSE:002547) shareholders have enjoyed a 87% share price rise over the last half decade, well in excess of the market return of around 43% (not including dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 11%.

Since it's been a strong week for Suzhou Chunxing Precision Mechanical shareholders, let's have a look at trend of the longer term fundamentals.

Given that Suzhou Chunxing Precision Mechanical didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. When a company doesn't make profits, we'd generally expect 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 5 years Suzhou Chunxing Precision Mechanical saw its revenue shrink by 19% per year. Even though revenue hasn't increased, the stock actually gained 13%, per year, during the same period. To us that suggests that there probably isn't a lot of correlation between the past revenue performance and the share price, but a closer look at analyst forecasts and the bottom line may well explain a lot.
