With a price-to-earnings (or "P/E") ratio of 28.7x Changzhou Qianhong Biopharma CO.,LTD (SZSE:002550) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 36x and even P/E's higher than 66x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Recent times haven't been advantageous for Changzhou Qianhong BiopharmaLTD as its earnings have been falling quicker than most other companies. The P/E is probably low because investors think this poor earnings performance isn't going to improve at all. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.
