Those holding Zhejiang Zhongjian Technology Co.,Ltd (SZSE:002779) shares would be relieved that the share price has rebounded 30% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. The last 30 days bring the annual gain to a very sharp 44%.

After such a large jump in price, Zhejiang Zhongjian TechnologyLtd may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 76.4x, since almost half of all companies in China have P/E ratios under 27x 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.

Zhejiang Zhongjian TechnologyLtd has been doing a good job lately as it's been growing earnings at a solid pace. One possibility is that the P/E is high because investors think this respectable earnings growth will be enough 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.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Zhejiang Zhongjian TechnologyLtd would need to produce outstanding growth well in excess of the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 26% last year. Although, its longer-term performance hasn't been as strong with three-year EPS growth being relatively non-existent overall. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

This is in contrast to the rest of the market, which is expected to grow by 35% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it concerning that Zhejiang Zhongjian TechnologyLtd is trading at a P/E higher than the market. 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. 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 Bottom Line On Zhejiang Zhongjian TechnologyLtd's P/E

Shares in Zhejiang Zhongjian TechnologyLtd have built up some good momentum lately, which has really inflated its P/E. 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 Zhejiang Zhongjian TechnologyLtd 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.
