Cheshi Technology Inc. (HKG:1490) shareholders are no doubt pleased to see that the share price has bounced 26% in the last month, although it is still struggling to make up recently lost ground. Looking back a bit further, it's encouraging to see the stock is up 45% in the last year.

Although its price has surged higher, it's still not a stretch to say that Cheshi Technology's price-to-earnings (or "P/E") ratio of 11.7x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 10x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

As an illustration, earnings have deteriorated at Cheshi Technology over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Growth For Cheshi Technology?

There's an inherent assumption that a company should be matching the market for P/E ratios like Cheshi Technology's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 36% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 69% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 22% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's somewhat alarming that Cheshi Technology's P/E sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh on the share price eventually.

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

Cheshi Technology appears to be back in favour with a solid price jump getting its P/E back in line with most other companies. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Cheshi Technology revealed its shrinking earnings over the medium-term aren't impacting its P/E 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 moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
