The Shenzhen Bestek Technology Co., Ltd. (SZSE:300822) share price has softened a substantial 34% over the previous 30 days, handing back much of the gains the stock has made lately. To make matters worse, the recent drop has wiped out a year's worth of gains with the share price now back where it started a year ago.

Even after such a large drop in price, Shenzhen Bestek Technology may still be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 58.8x, 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. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

With earnings growth that's exceedingly strong of late, Shenzhen Bestek 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. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Shenzhen Bestek Technology's Growth Trending?

In order to justify its P/E ratio, Shenzhen Bestek Technology would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings growth, the company posted a terrific increase of 33%. However, this wasn't enough as the latest three year period has seen a very unpleasant 70% drop in EPS in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 36% shows it's an unpleasant look.

With this information, we find it concerning that Shenzhen Bestek 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 Final Word

Shenzhen Bestek Technology's shares may have retreated, but its P/E is still flying high. 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 Shenzhen Bestek 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.
