When close to half the companies in China have price-to-earnings ratios (or "P/E's") above 30x, you may consider Ningbo Construction Co., Ltd. (SHSE:601789) as a highly attractive investment with its 12x P/E ratio. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

For example, consider that Ningbo Construction's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Growth For Ningbo Construction?

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

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 5.1%. Even so, admirably EPS has lifted 34% in aggregate from three years ago, notwithstanding the last 12 months. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Ningbo Construction's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Final Word
