It's not a stretch to say that Guangzhou Baiyunshan Pharmaceutical Holdings Company Limited's (HKG:874) price-to-earnings (or "P/E") ratio of 7.7x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. 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.

Recent earnings growth for Guangzhou Baiyunshan Pharmaceutical Holdings has been in line with the market. The P/E is probably moderate because investors think this modest earnings performance will continue. If this is the case, then at least existing shareholders won't be losing sleep over the current share price.

What Are Growth Metrics Telling Us About The P/E?

In order to justify its P/E ratio, Guangzhou Baiyunshan Pharmaceutical Holdings would need to produce growth that's similar to the market.

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. Fortunately, a few good years before that means that it was still able to grow EPS by 22% in total over the last three years. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Looking ahead now, EPS is anticipated to slump, contracting by 2.4% per year during the coming three years according to the five analysts following the company. With the market predicted to deliver 16% growth per year, that's a disappointing outcome.

With this information, we find it concerning that Guangzhou Baiyunshan Pharmaceutical Holdings is trading at a fairly similar P/E to the market. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. There's a good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the negative growth outlook.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.
