Tong Petrotech Corp.'s (SZSE:300164) price-to-earnings (or "P/E") ratio of 22.1x 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 27x and even P/E's above 48x 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 limited.

Tong Petrotech certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Is There Any Growth For Tong Petrotech?

Tong Petrotech'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.

If we review the last year of earnings growth, the company posted a terrific increase of 446%. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

This is in contrast to the rest of the market, which is expected to grow by 42% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's understandable that Tong Petrotech's P/E sits below the majority of other companies. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

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 Tong Petrotech maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
