The Jiangxi Huawu Brake Co.,Ltd. (SZSE:300095) share price has fared very poorly over the last month, falling by a substantial 26%. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 43% share price drop.

In spite of the heavy fall in price, Jiangxi Huawu BrakeLtd's price-to-earnings (or "P/E") ratio of 65.5x 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.

As an illustration, earnings have deteriorated at Jiangxi Huawu BrakeLtd 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 Jiangxi Huawu BrakeLtd's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Jiangxi Huawu BrakeLtd's is when the company's growth is on track to outshine the market decidedly.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 64%. This means it has also seen a slide in earnings over the longer-term as EPS is down 78% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 42% 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 Jiangxi Huawu BrakeLtd'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

Even after such a strong price drop, Jiangxi Huawu BrakeLtd's P/E still exceeds the rest of the market significantly. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Jiangxi Huawu BrakeLtd currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. 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.
