It's not a stretch to say that Zhuzhou CRRC Times Electric Co., Ltd.'s (HKG:3898) price-to-earnings (or "P/E") ratio of 9.1x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

Zhuzhou CRRC Times Electric certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It might be that many expect the strong earnings performance to deteriorate like the rest, which has kept the P/E from rising. 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 not quite in favour.

Does Growth Match The P/E?

In order to justify its P/E ratio, Zhuzhou CRRC Times Electric would need to produce growth that's similar to the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 28% last year. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 4.2% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Turning to the outlook, the next year should generate growth of 9.3% as estimated by the analysts watching the company. That's shaping up to be materially lower than the 22% growth forecast for the broader market.

In light of this, it's curious that Zhuzhou CRRC Times Electric's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Zhuzhou CRRC Times Electric currently trades on a higher than expected P/E since its forecast growth is lower than the wider market. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
