For many investors, the main point of stock picking is to generate higher returns than the overall market. But if you try your hand at stock picking, your risk returning less than the market. Unfortunately, that's been the case for longer term Shenzhen InfoGem Technologies Co., Ltd. (SZSE:300085) shareholders, since the share price is down 45% in the last three years, falling well short of the market decline of around 12%. On top of that, the share price is down 5.6% in the last week.

Since Shenzhen InfoGem Technologies has shed CN¥509m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

Given that Shenzhen InfoGem Technologies 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. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Over the last three years, Shenzhen InfoGem Technologies' revenue dropped 8.1% per year. That is not a good result. The stock has disappointed holders over the last three years, falling 13%, annualized. And with no profits, and weak revenue, are you surprised? Of course, sentiment could become too negative, and the company may actually be making progress to profitability.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

It's nice to see that Shenzhen InfoGem Technologies shareholders have received a total shareholder return of 30% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 6% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
