With a price-to-earnings (or "P/E") ratio of 32.2x Zhejiang Wolwo Bio-Pharmaceutical Co., Ltd. (SZSE:300357) may be sending bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 28x and even P/E's lower than 17x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

Zhejiang Wolwo Bio-Pharmaceutical hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, 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.

How Is Zhejiang Wolwo Bio-Pharmaceutical's Growth Trending?

In order to justify its P/E ratio, Zhejiang Wolwo Bio-Pharmaceutical would need to produce impressive growth in excess of the market.

Retrospectively, the last year delivered a frustrating 3.2% decrease to the company's bottom line. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 22% each year during the coming three years according to the four analysts following the company. With the market predicted to deliver 24% growth each year, the company is positioned for a weaker earnings result.

With this information, we find it concerning that Zhejiang Wolwo Bio-Pharmaceutical is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as this level of earnings growth 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.

Our examination of Zhejiang Wolwo Bio-Pharmaceutical's analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
