Zhejiang Supor Co., Ltd.'s (SZSE:002032) price-to-earnings (or "P/E") ratio of 19.7x 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 35x and even P/E's above 65x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Recent times have been pleasing for Zhejiang Supor as its earnings have risen in spite of the market's earnings going into reverse. 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 Zhejiang Supor?

There's an inherent assumption that a company should underperform the market for P/E ratios like Zhejiang Supor's to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 6.0%. EPS has also lifted 24% in aggregate from three years ago, partly thanks to the last 12 months of growth. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 11% over the next year. That's shaping up to be materially lower than the 44% growth forecast for the broader market.

With this information, we can see why Zhejiang Supor is trading at a P/E lower than the market. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.
