Shenzhen JT Automation Equipment Co.,Ltd (SZSE:300400) shareholders that were waiting for something to happen have been dealt a blow with a 27% share price drop in the last month. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 34% share price drop.

In spite of the heavy fall in price, Shenzhen JT Automation EquipmentLtd's price-to-earnings (or "P/E") ratio of 50.5x might still 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 30x and even P/E's below 18x 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.

With earnings growth that's exceedingly strong of late, Shenzhen JT Automation EquipmentLtd 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Shenzhen JT Automation EquipmentLtd's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered an exceptional 30% gain to the company's bottom line. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 53% overall. 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 42% 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 JT Automation EquipmentLtd 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. 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.

The Key Takeaway

Even after such a strong price drop, Shenzhen JT Automation EquipmentLtd's P/E still exceeds the rest of the market significantly. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Shenzhen JT Automation EquipmentLtd 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. 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.
