There's Reason For Concern Over ComNav Technology Ltd.'s (SHSE:688592) Massive 34% Price Jump

ComNav Technology Ltd. (SHSE:688592) shareholders are no doubt pleased to see that the share price has bounced 34% in the last month, although it is still struggling to make up recently lost ground. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Following the firm bounce in price, ComNav Technology's price-to-earnings (or "P/E") ratio of 58.5x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 29x and even P/E's below 18x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

For example, consider that ComNav Technology's financial performance has been pretty ordinary lately as earnings growth is non-existent. One possibility is that the P/E is high because investors think the benign earnings growth will improve to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

The only time you'd be truly comfortable seeing a P/E as steep as ComNav Technology's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. Still, the latest three year period was better as it's delivered a decent 7.7% overall rise in EPS. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the market, which is expected to grow by 41% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that ComNav Technology's 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

ComNav Technology's P/E is flying high just like its stock has during the last month. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of ComNav Technology 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.
