Hengtong Logistics Co., Ltd. (SHSE:603223) shares have had a really impressive month, gaining 25% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 39% over that time.

After such a large jump in price, Hengtong Logistics may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 49.4x, since almost half of all companies in China have P/E ratios under 27x and even P/E's lower than 16x 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 example, consider that Hengtong Logistics' financial performance has been poor lately as its earnings have been in decline. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Growth For Hengtong Logistics?

In order to justify its P/E ratio, Hengtong Logistics would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered a frustrating 15% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 49% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 36% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's alarming that Hengtong Logistics' 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 Bottom Line On Hengtong Logistics' P/E

Hengtong Logistics' P/E is flying high just like its stock has during the last month. 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 Hengtong Logistics currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
