With a median price-to-earnings (or "P/E") ratio of close to 31x in China, you could be forgiven for feeling indifferent about Glarun Technology Co.,Ltd's (SHSE:600562) P/E ratio of 28.9x. 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 growth that's superior to most other companies of late, Glarun TechnologyLtd has been doing relatively well. One possibility is that the P/E is moderate because investors think this strong earnings performance might be about to tail off. 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.

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

There's an inherent assumption that a company should be matching the market for P/E ratios like Glarun TechnologyLtd's to be considered reasonable.

Retrospectively, the last year delivered a decent 4.3% gain to the company's bottom line. The latest three year period has also seen a 24% overall rise in EPS, aided somewhat by its short-term performance. 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 21% each year during the coming three years according to the five analysts following the company. Meanwhile, the rest of the market is forecast to expand by 25% per year, which is noticeably more attractive.

With this information, we find it interesting that Glarun TechnologyLtd is trading at a fairly similar P/E to the market. 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 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 Glarun TechnologyLtd 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.

Before you settle on your opinion, we've discovered 1 warning sign for Glarun TechnologyLtd that you should be aware of.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
