With a price-to-earnings (or "P/E") ratio of 46.1x TKD Science and Technology Co.,Ltd. (SHSE:603738) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 30x and even P/E's lower than 18x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For instance, TKD Science and TechnologyLtd's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. 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?

The only time you'd be truly comfortable seeing a P/E as steep as TKD Science and TechnologyLtd's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 17% decrease to the company's bottom line. That put a dampener on the good run it was having over the longer-term as its three-year EPS growth is still a noteworthy 16% in total. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of earnings growth.

This is in contrast to the rest of the market, which is expected to grow by 37% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it concerning that TKD Science and TechnologyLtd 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. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Final Word

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.

Our examination of TKD Science and TechnologyLtd 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. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. 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.

You should always think about risks. Case in point, we've spotted 1 warning sign for TKD Science and TechnologyLtd you should be aware of.
