The Zhejiang Great Shengda Packaging Co.,Ltd. (SHSE:603687) share price has fared very poorly over the last month, falling by a substantial 27%. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 19% share price drop.

Even after such a large drop in price, given close to half the companies in China have price-to-earnings ratios (or "P/E's") below 26x, you may still consider Zhejiang Great Shengda PackagingLtd as a stock to avoid entirely with its 44.1x P/E ratio. 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.

As an illustration, earnings have deteriorated at Zhejiang Great Shengda PackagingLtd over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Zhejiang Great Shengda PackagingLtd's Growth Trending?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Zhejiang Great Shengda PackagingLtd's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 21%. The last three years don't look nice either as the company has shrunk EPS by 41% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's an unpleasant look.

With this information, we find it concerning that Zhejiang Great Shengda PackagingLtd 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. 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 Zhejiang Great Shengda PackagingLtd's P/E

A significant share price dive has done very little to deflate Zhejiang Great Shengda PackagingLtd's very lofty P/E. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Zhejiang Great Shengda PackagingLtd 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
