Shanghai QiFan Cable Co., Ltd's (SHSE:605222) price-to-earnings (or "P/E") ratio of 12.7x 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 33x and even P/E's above 59x 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.

With earnings growth that's exceedingly strong of late, Shanghai QiFan Cable has been doing very well. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. 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.

Is There Any Growth For Shanghai QiFan Cable?

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

If we review the last year of earnings growth, the company posted a terrific increase of 36%. Pleasingly, EPS has also lifted 92% in aggregate from three years ago, thanks to the last 12 months of growth. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 37% shows it's noticeably less attractive on an annualised basis.

With this information, we can see why Shanghai QiFan Cable 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

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Shanghai QiFan Cable revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. 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.
