With a price-to-earnings (or "P/E") ratio of 49.3x Shenzhen Tellus Holding Co., Ltd. (SZSE:000025) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 31x and even P/E's lower than 19x 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.

Recent times have been quite advantageous for Shenzhen Tellus Holding as its earnings have been rising very briskly. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

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

There's an inherent assumption that a company should far outperform the market for P/E ratios like Shenzhen Tellus Holding's to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 71%. The latest three year period has also seen an excellent 78% overall rise in EPS, aided by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

This is in contrast to the rest of the market, which is expected to grow by 38% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it concerning that Shenzhen Tellus Holding is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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 Key Takeaway

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Shenzhen Tellus Holding currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. 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.
