Tianjin Port Holdings Co., Ltd.'s (SHSE:600717) price-to-earnings (or "P/E") ratio of 12.9x 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 27x and even P/E's above 51x 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.

The earnings growth achieved at Tianjin Port Holdings over the last year would be more than acceptable for most companies. One possibility is that the P/E is low because investors think this respectable earnings growth might actually underperform the broader market in the near future. 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.

How Is Tianjin Port Holdings' Growth Trending?

In order to justify its P/E ratio, Tianjin Port Holdings would need to produce anemic growth that's substantially trailing the market.

If we review the last year of earnings growth, the company posted a terrific increase of 17%. Pleasingly, EPS has also lifted 32% 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.

This is in contrast to the rest of the market, which is expected to grow by 36% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we can see why Tianjin Port Holdings is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Final Word

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Tianjin Port Holdings revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price rising strongly in the near future under these circumstances.
