With a price-to-earnings (or "P/E") ratio of 13.4x Luenmei Quantum Co.,Ltd (SHSE:600167) may be sending very bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 30x and even P/E's higher than 53x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Luenmei QuantumLtd certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. 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 you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

How Is Luenmei QuantumLtd's Growth Trending?

Luenmei QuantumLtd's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered virtually the same number to the company's bottom line as the year before. Whilst it's an improvement, it wasn't enough to get the company out of the hole it was in, with earnings down 47% overall from three years ago. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Looking ahead now, EPS is anticipated to climb by 24% during the coming year according to the four analysts following the company. With the market predicted to deliver 41% growth , the company is positioned for a weaker earnings result.

In light of this, it's understandable that Luenmei QuantumLtd'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.

The Bottom Line On Luenmei QuantumLtd's P/E
