Shanghai Baosteel Packaging Co., Ltd.'s (SHSE:601968) price-to-earnings (or "P/E") ratio of 22.8x 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 32x and even P/E's above 57x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Shanghai Baosteel Packaging could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. The P/E is probably low because investors think this poor earnings performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

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

Shanghai Baosteel Packaging'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.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 4.6%. As a result, earnings from three years ago have also fallen 3.2% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Turning to the outlook, the next year should generate growth of 15% as estimated by the lone analyst watching the company. Meanwhile, the rest of the market is forecast to expand by 40%, which is noticeably more attractive.

In light of this, it's understandable that Shanghai Baosteel Packaging'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 Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Shanghai Baosteel Packaging 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.
