There wouldn't be many who think Water Oasis Group Limited's (HKG:1161) price-to-earnings (or "P/E") ratio of 9.2x is worth a mention when the median P/E in Hong Kong is similar at about 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.

AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early.

As an illustration, earnings have deteriorated at Water Oasis Group over the last year, which is not ideal at all. 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 you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Water Oasis Group's Growth Trending?

The only time you'd be comfortable seeing a P/E like Water Oasis Group's is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered a frustrating 38% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 60% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 18% 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 Water Oasis Group is trading at a fairly similar P/E to 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 on the share price eventually.

What We Can Learn From Water Oasis Group's P/E?

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Water Oasis Group 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.

Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
