With a median price-to-earnings (or "P/E") ratio of close to 10x in Hong Kong, you could be forgiven for feeling indifferent about Cheshi Technology Inc.'s (HKG:1490) P/E ratio of 9.6x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

For instance, Cheshi Technology's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The P/E?

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. The last three years don't look nice either as the company has shrunk EPS by 69% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's an unpleasant look.

With this information, we find it concerning that Cheshi Technology is trading at a fairly similar P/E to the market. 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?

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.

We've established that Cheshi Technology currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. 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. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
