Aisino Co.Ltd.'s (SHSE:600271) price-to-earnings (or "P/E") ratio of 16.5x might make it look like a strong buy right now compared to the market in China, where around half of the companies have P/E ratios above 35x and even P/E's above 63x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

With its earnings growth in positive territory compared to the declining earnings of most other companies, AisinoLtd 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.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as depressed as AisinoLtd's is when the company's growth is on track to lag the market decidedly.

If we review the last year of earnings growth, the company posted a terrific increase of 38%. The latest three year period has also seen an excellent 166% 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 dual analysts covering the company suggest earnings growth is heading into negative territory, declining 15% over the next year. With the market predicted to deliver 44% growth , that's a disappointing outcome.

In light of this, it's understandable that AisinoLtd's P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Bottom Line On AisinoLtd's P/E

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that AisinoLtd maintains its low P/E on the weakness of its forecast for sliding earnings, as expected.
