China Resources Boya Bio-pharmaceutical Group Co.,Ltd (SZSE:300294) shareholders should be happy to see the share price up 11% in the last month. If you look at the last three years, the stock price is down. But that's not so bad when you consider its market is down 25%.

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.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

China Resources Boya Bio-pharmaceutical GroupLtd saw its EPS decline at a compound rate of 13% per year, over the last three years. This fall in the EPS is worse than the 4% compound annual share price fall. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in. This positive sentiment is also reflected in the generous P/E ratio of 72.89.

A Different Perspective

It's nice to see that China Resources Boya Bio-pharmaceutical GroupLtd shareholders have received a total shareholder return of 9.4% over the last year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 1.1% 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.
