When close to half the companies in China have price-to-earnings ratios (or "P/E's") above 28x, you may consider China Nuclear Engineering Corporation Limited (SHSE:601611) as a highly attractive investment with its 11.2x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

China Nuclear Engineering's earnings growth of late has been pretty similar to most other companies. It might be that many expect the mediocre earnings performance to degrade, which has repressed the P/E. If not, then existing shareholders have reason to be optimistic about the future direction of the share price.

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

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

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. Although pleasingly EPS has lifted 41% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 20% per year as estimated by the four analysts watching the company. That's shaping up to be materially lower than the 24% per year growth forecast for the broader market.

With this information, we can see why China Nuclear Engineering 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

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of China Nuclear Engineering's analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with China Nuclear Engineering (at least 1 which makes us a bit uncomfortable), and understanding them should be part of your investment process.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
