Shijihengtong Technology Co., Ltd. (SZSE:301428) shareholders would be excited to see that the share price has had a great month, posting a 37% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 12% in the last twelve months.

Following the firm bounce in price, Shijihengtong Technology's price-to-earnings (or "P/E") ratio of 37.8x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 33x and even P/E's below 19x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Shijihengtong Technology over the last year, which is not ideal at all. 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 Shijihengtong Technology's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as high as Shijihengtong Technology's is when the company's growth is on track to outshine the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 15%. This means it has also seen a slide in earnings over the longer-term as EPS is down 8.4% in total over the last three years. 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 37% 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 Shijihengtong 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

What We Can Learn From Shijihengtong Technology's P/E?

Shijihengtong Technology's P/E is getting right up there since its shares have risen strongly. 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 Shijihengtong 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. 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.
