With a price-to-earnings (or "P/E") ratio of 43.6x Northeast Securities Co., Ltd. (SZSE:000686) may be sending very bearish signals at the moment, given that 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 highly elevated P/E.

For instance, Northeast Securities' receding earnings in recent times would have to be some food for thought. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

The only time you'd be truly comfortable seeing a P/E as steep as Northeast Securities' is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 63% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 76% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

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 Northeast Securities' 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 Northeast Securities' P/E

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Northeast Securities 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. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
