Dalian Demaishi Precision Technology Co., Ltd. (SZSE:301007) shares have had a really impressive month, gaining 28% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 21% over that time.

After such a large jump in price, Dalian Demaishi Precision Technology may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 39.5x, since almost half of all companies in China have P/E ratios under 28x and even P/E's lower than 17x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

With earnings growth that's exceedingly strong of late, Dalian Demaishi Precision Technology has been doing very well. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, 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.

Is There Enough Growth For Dalian Demaishi Precision Technology?

Dalian Demaishi Precision Technology's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 32%. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 27% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 36% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Dalian Demaishi Precision Technology is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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.

The Bottom Line On Dalian Demaishi Precision Technology's P/E

The large bounce in Dalian Demaishi Precision Technology's shares has lifted the company's P/E to a fairly high level. 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 Dalian Demaishi Precision Technology revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. 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.
