Zhejiang Sunoren Solar Technology Co.,Ltd. (SHSE:603105) shares have had a horrible month, losing 26% after a relatively good period beforehand. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 53% loss during that time.

Although its price has dipped substantially, given about half the companies in China have price-to-earnings ratios (or "P/E's") above 28x, you may still consider Zhejiang Sunoren Solar TechnologyLtd as an attractive investment with its 18.7x P/E ratio. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Zhejiang Sunoren Solar TechnologyLtd certainly has been doing a good job lately as it's been growing earnings more than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. 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.

What Are Growth Metrics Telling Us About The Low P/E?

Zhejiang Sunoren Solar TechnologyLtd'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.

Retrospectively, the last year delivered a decent 3.0% gain to the company's bottom line. This was backed up an excellent period prior to see EPS up by 182% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the four analysts covering the company suggest earnings should grow by 20% per year over the next three years. That's shaping up to be materially lower than the 25% per year growth forecast for the broader market.

With this information, we can see why Zhejiang Sunoren Solar TechnologyLtd 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.

What We Can Learn From Zhejiang Sunoren Solar TechnologyLtd's P/E?

The softening of Zhejiang Sunoren Solar TechnologyLtd's shares means its P/E is now sitting at a pretty low level. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.
