With a price-to-earnings (or "P/E") ratio of 44.5x Hengbao Co.,Ltd. (SZSE:002104) may be sending bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 36x and even P/E's lower than 20x 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.

As an illustration, earnings have deteriorated at HengbaoLtd over the last year, which is not ideal at all. 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.

How Is HengbaoLtd's Growth Trending?

In order to justify its P/E ratio, HengbaoLtd would need to produce impressive growth 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 25%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 38% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that HengbaoLtd's P/E sits above the majority of other companies. 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. 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

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that HengbaoLtd 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.

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