Medicalsystem Biotechnology Co., Ltd's (SZSE:300439) price-to-earnings (or "P/E") ratio of 16.7x might make it look like a strong buy right now compared to the market in China, where around half of the companies have P/E ratios above 34x and even P/E's above 65x are quite common. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Medicalsystem Biotechnology 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 degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Growth For Medicalsystem Biotechnology?

In order to justify its P/E ratio, Medicalsystem Biotechnology would need to produce anemic growth that's substantially trailing the market.

If we review the last year of earnings growth, the company posted a worthy increase of 14%. The solid recent performance means it was also able to grow EPS by 16% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

This is in contrast to the rest of the market, which is expected to grow by 36% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's understandable that Medicalsystem Biotechnology's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Medicalsystem Biotechnology revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.

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