With a price-to-earnings (or "P/E") ratio of 62x GHT Co.,Ltd (SZSE:300711) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 26x and even P/E's lower than 16x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

GHTLtd has been doing a decent job lately as it's been growing earnings at a reasonable pace. One possibility is that the P/E is high because investors think this good earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

GHTLtd's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a decent 4.0% gain to the company's bottom line. Pleasingly, EPS has also lifted 120% 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 superb for the company.

Comparing that to the market, which is predicted to deliver 36% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

In light of this, it's alarming that GHTLtd's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From GHTLtd's P/E?

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.

Our examination of GHTLtd revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

You should always think about risks. Case in point, we've spotted 1 warning sign for GHTLtd you should be aware of.
