GRG Banking Equipment Co., Ltd. (SZSE:002152) shareholders would be excited to see that the share price has had a great month, posting a 38% gain and recovering from prior weakness. Notwithstanding the latest gain, the annual share price return of 4.8% isn't as impressive.

Even after such a large jump in price, it's still not a stretch to say that GRG Banking Equipment's price-to-earnings (or "P/E") ratio of 31.9x right now seems quite "middle-of-the-road" compared to the market in China, where the median P/E ratio is around 34x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

GRG Banking Equipment 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. One possibility is that the P/E is moderate because investors think the company's earnings will be less resilient moving forward. If not, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

What Are Growth Metrics Telling Us About The P/E?

In order to justify its P/E ratio, GRG Banking Equipment would need to produce growth that's similar to the market.

If we review the last year of earnings growth, the company posted a worthy increase of 14%. EPS has also lifted 26% in aggregate from three years ago, partly thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Looking ahead now, EPS is anticipated to climb by 14% per annum during the coming three years according to the three analysts following the company. Meanwhile, the rest of the market is forecast to expand by 19% per annum, which is noticeably more attractive.

With this information, we find it interesting that GRG Banking Equipment is trading at a fairly similar P/E to the market. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

The Key Takeaway

GRG Banking Equipment's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. 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 GRG Banking Equipment 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.
