Grandblue Environment Co., Ltd.'s (SHSE:600323) price-to-earnings (or "P/E") ratio of 8.8x 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 32x and even P/E's above 60x are quite common. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Recent times have been advantageous for Grandblue Environment as its earnings have been rising faster 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?

Grandblue Environment'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.

Taking a look back first, we see that the company grew earnings per share by an impressive 31% last year. Pleasingly, EPS has also lifted 44% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Looking ahead now, EPS is anticipated to climb by 11% during the coming year according to the seven analysts following the company. With the market predicted to deliver 39% growth , the company is positioned for a weaker earnings result.

With this information, we can see why Grandblue Environment is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Final Word

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Grandblue Environment maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
