Those holding Xuchang KETOP Testing Research Institute Co.,Ltd (SZSE:003008) shares would be relieved that the share price has rebounded 28% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 25% in the last twelve months.

Even after such a large jump in price, Xuchang KETOP Testing Research InstituteLtd may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 26.5x, since almost half of all companies in China have P/E ratios greater than 31x and even P/E's higher than 56x 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 limited.

For instance, Xuchang KETOP Testing Research InstituteLtd's receding earnings in recent times would have to be some food for thought. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

How Is Xuchang KETOP Testing Research InstituteLtd's Growth Trending?

Xuchang KETOP Testing Research InstituteLtd's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

Retrospectively, the last year delivered a frustrating 4.7% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 41% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's an unpleasant look.

In light of this, it's understandable that Xuchang KETOP Testing Research InstituteLtd's P/E would sit below the majority of other companies. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

Xuchang KETOP Testing Research InstituteLtd's stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. 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.

As we suspected, our examination of Xuchang KETOP Testing Research InstituteLtd revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
