With a price-to-earnings (or "P/E") ratio of 8.8x Sichuan Expressway Company Limited (HKG:107) may be sending bullish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios greater than 13x and even P/E's higher than 27x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Recent times have been quite advantageous for Sichuan Expressway as its earnings have been rising very briskly. 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.

How Is Sichuan Expressway's Growth Trending?

In order to justify its P/E ratio, Sichuan Expressway would need to produce sluggish growth that's trailing the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 34% last year. However, this wasn't enough as the latest three year period has seen a very unpleasant 16% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 19% shows it's an unpleasant look.

With this information, we are not surprised that Sichuan Expressway is trading at a P/E lower than the market. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Sichuan Expressway maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.

Having said that, be aware Sichuan Expressway is showing 2 warning signs in our investment analysis, and 1 of those is a bit concerning.
