Unfortunately for some shareholders, the Yinchuan Weili Transmission Technology Co., Ltd. (SZSE:300904) share price has dived 28% in the last thirty days, prolonging recent pain. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

Although its price has dipped substantially, Yinchuan Weili Transmission Technology may still be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 66.9x, since almost half of all companies in China have P/E ratios under 26x and even P/E's lower than 16x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For example, consider that Yinchuan Weili Transmission Technology's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do 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?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Yinchuan Weili Transmission Technology's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 24% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 68% in aggregate. 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 41% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Yinchuan Weili Transmission 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 Key Takeaway

A significant share price dive has done very little to deflate Yinchuan Weili Transmission Technology's very lofty P/E. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Yinchuan Weili Transmission 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
