The past three years for Centre Testing International Group (SZSE:300012) investors has not been profitable

Many investors define successful investing as beating the market average over the long term. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term Centre Testing International Group Co. Ltd. (SZSE:300012) shareholders, since the share price is down 40% in the last three years, falling well short of the market decline of around 13%. Shareholders have had an even rougher run lately, with the share price down 15% in the last 90 days. However, one could argue that the price has been influenced by the general market, which is down 8.5% in the same timeframe.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

Check out our latest analysis for Centre Testing International Group

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

During the unfortunate three years of share price decline, Centre Testing International Group actually saw its earnings per share (EPS) improve by 7.6% per year. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

With a rather small yield of just 0.8% we doubt that the stock's share price is based on its dividend. We note that, in three years, revenue has actually grown at a 11% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Centre Testing International Group further; while we may be missing something on this analysis, there might also be an opportunity.

We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm.
