The Nanfang Communication Holdings Limited (HKG:1617) share price has done very well over the last month, posting an excellent gain of 26%. The last 30 days bring the annual gain to a very sharp 28%.
Since its price has surged higher, Nanfang Communication Holdings' price-to-earnings (or "P/E") ratio of 19.5x might make it look like a strong sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 5x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.
For example, consider that Nanfang Communication Holdings' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?
There's an inherent assumption that a company should far outperform the market for P/E ratios like Nanfang Communication Holdings' to be considered reasonable.
Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 38%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.
Comparing that to the market, which is predicted to deliver 21% 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 Nanfang Communication Holdings' P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.
The Final Word
Nanfang Communication Holdings' P/E is flying high just like its stock has during the last month. 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 Nanfang Communication Holdings 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. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
