Anhui Huaqi Environmental Protection & Technology Co., Ltd. (SZSE:300929) shareholders that were waiting for something to happen have been dealt a blow with a 30% share price drop in the last month. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 28% in that time.

Although its price has dipped substantially, Anhui Huaqi Environmental Protection & Technology's price-to-earnings (or "P/E") ratio of 62.3x might still make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 27x and even P/E's below 17x are quite common. 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 Anhui Huaqi Environmental Protection & Technology's financial performance has been poor lately as its earnings have been in decline. 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 Anhui Huaqi Environmental Protection & Technology's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Anhui Huaqi Environmental Protection & Technology's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 74% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 81% 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 41% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Anhui Huaqi Environmental Protection & Technology is trading at a P/E higher than the market. 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 Final Word

Anhui Huaqi Environmental Protection & Technology's shares may have retreated, but its P/E is still flying high. 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.

Our examination of Anhui Huaqi Environmental Protection & Technology 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. 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.
