With a median price-to-earnings (or "P/E") ratio of close to 35x in China, you could be forgiven for feeling indifferent about Hangzhou Oxygen Plant Group Co.,Ltd.'s (SZSE:002430) P/E ratio of 34.8x. 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.

With earnings that are retreating more than the market's of late, Hangzhou Oxygen Plant GroupLtd has been very sluggish. One possibility is that the P/E is moderate because investors think the company's earnings trend will eventually fall in line with most others in the market. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

Hangzhou Oxygen Plant GroupLtd's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

Retrospectively, the last year delivered a frustrating 43% decrease to the company's bottom line. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Shifting to the future, estimates from the nine analysts covering the company suggest earnings should grow by 86% over the next year. With the market only predicted to deliver 43%, the company is positioned for a stronger earnings result.

In light of this, it's curious that Hangzhou Oxygen Plant GroupLtd's P/E sits in line with the majority of other companies. It may be that most investors aren't convinced the company can achieve future growth expectations.

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.

We've established that Hangzhou Oxygen Plant GroupLtd currently trades on a lower than expected P/E since its forecast growth is higher than the wider market. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing pressure on the P/E ratio. It appears some are indeed anticipating earnings instability, because these conditions should normally provide a boost to the share price.
