SMARTGEN (Zhengzhou) Technology Co., Ltd.'s (SZSE:301361) 31% Share Price Surge Not Quite Adding Up

SMARTGEN (Zhengzhou) Technology Co., Ltd. (SZSE:301361) shareholders have had their patience rewarded with a 31% share price jump in the last month. The annual gain comes to 107% following the latest surge, making investors sit up and take notice.

After such a large jump in price, given close to half the companies in China have price-to-earnings ratios (or "P/E's") below 38x, you may consider SMARTGEN (Zhengzhou) Technology as a stock to avoid entirely with its 60.4x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

For instance, SMARTGEN (Zhengzhou) Technology's receding earnings in recent times would have to be some food for thought. 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.

How Is SMARTGEN (Zhengzhou) Technology's Growth Trending?

In order to justify its P/E ratio, SMARTGEN (Zhengzhou) Technology would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 5.3%. As a result, earnings from three years ago have also fallen 22% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 36% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's alarming that SMARTGEN (Zhengzhou) Technology's P/E sits above the majority of other companies. 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 SMARTGEN (Zhengzhou) Technology's P/E

Shares in SMARTGEN (Zhengzhou) Technology have built up some good momentum lately, which has really inflated its P/E. 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 SMARTGEN (Zhengzhou) Technology currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. 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.
