With a price-to-earnings (or "P/E") ratio of 59x Eternal Asia Supply Chain Management Ltd. (SZSE:002183) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 29x 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, Eternal Asia Supply Chain Management's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. 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?

In order to justify its P/E ratio, Eternal Asia Supply Chain Management would need to produce outstanding growth well in excess of the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 42%. As a result, earnings from three years ago have also fallen 50% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 37% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Eternal Asia Supply Chain Management's P/E sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate 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 Bottom Line On Eternal Asia Supply Chain Management's P/E

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 Eternal Asia Supply Chain Management revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely 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.
