Guizhou Sanli Pharmaceutical Co.,Ltd (SHSE:603439) shareholders won't be pleased to see that the share price has had a very rough month, dropping 30% and undoing the prior period's positive performance. Longer-term shareholders would now have taken a real hit with the stock declining 6.1% in the last year.

Even after such a large drop in price, Guizhou Sanli PharmaceuticalLtd may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 22.1x, since almost half of all companies in China have P/E ratios greater than 27x and even P/E's higher than 48x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Guizhou Sanli PharmaceuticalLtd has been doing quite well of late. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Is There Any Growth For Guizhou Sanli PharmaceuticalLtd?

Guizhou Sanli PharmaceuticalLtd's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 81%. The latest three year period has also seen an excellent 186% overall rise in EPS, aided by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the four analysts covering the company suggest earnings should grow by 22% over the next year. Meanwhile, the rest of the market is forecast to expand by 42%, which is noticeably more attractive.

With this information, we can see why Guizhou Sanli PharmaceuticalLtd is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.
