With a price-to-earnings (or "P/E") ratio of 11.8x IVD Medical Holding Limited (HKG:1931) may be sending bearish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios under 8x and even P/E's lower than 5x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

IVD Medical Holding has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

IVD Medical Holding's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Retrospectively, the last year delivered a decent 13% gain to the company's bottom line. The latest three year period has also seen an excellent 47% overall rise in EPS, aided somewhat by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Comparing that to the market, which is predicted to deliver 21% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we find it concerning that IVD Medical Holding is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates 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 heavily on the share price eventually.

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.

Our examination of IVD Medical Holding revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with IVD Medical Holding, and understanding should be part of your investment process.
