Those holding Changzheng Engineering Technology Co.,Ltd (SHSE:603698) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 20% over that time.

Following the firm bounce in price, Changzheng Engineering TechnologyLtd's price-to-earnings (or "P/E") ratio of 40.1x might make it look like a 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 high for a reason and it requires further investigation to determine if it's justified.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Changzheng Engineering TechnologyLtd has been doing quite well of late. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Changzheng Engineering TechnologyLtd's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, we see that the company managed to grow earnings per share by a handy 6.3% last year. Pleasingly, EPS has also lifted 36% 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.

Looking ahead now, EPS is anticipated to climb by 50% during the coming year according to the two analysts following the company. That's shaping up to be materially higher than the 41% growth forecast for the broader market.

With this information, we can see why Changzheng Engineering TechnologyLtd is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Bottom Line On Changzheng Engineering TechnologyLtd's P/E

The large bounce in Changzheng Engineering TechnologyLtd's shares has lifted the company's P/E to a fairly high level. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Changzheng Engineering TechnologyLtd maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
