Joinn Laboratories(China)Co.,Ltd.'s (SHSE:603127) price-to-earnings (or "P/E") ratio of 20.3x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 33x and even P/E's above 59x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Joinn Laboratories(China)Co.Ltd has been struggling lately as its earnings have declined faster 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.

Does Growth Match The Low P/E?

Joinn Laboratories(China)Co.Ltd'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, dishearteningly the company's profits fell to the tune of 17%. Even so, admirably EPS has lifted 152% in aggregate from three years ago, notwithstanding the last 12 months. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

In light of this, it's understandable that Joinn Laboratories(China)Co.Ltd's P/E sits below the majority of other companies. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.
