Shenzhen Zhilai Sci and Tech Co., Ltd.'s (SZSE:300771) price-to-earnings (or "P/E") ratio of 61x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 28x and even P/E's below 17x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

For example, consider that Shenzhen Zhilai Sci and Tech'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.

Is There Enough Growth For Shenzhen Zhilai Sci and Tech?

In order to justify its P/E ratio, Shenzhen Zhilai Sci and Tech 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 67%. The last three years don't look nice either as the company has shrunk EPS by 80% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

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.

With this information, we find it concerning that Shenzhen Zhilai Sci and Tech 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.

What We Can Learn From Shenzhen Zhilai Sci and Tech's 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 Shenzhen Zhilai Sci and Tech 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.
