Jiangyin Electrical Alloy Co.,Ltd (SZSE:300697) shares have continued their recent momentum with a 25% gain in the last month alone. Looking further back, the 12% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Even after such a large jump in price, there still wouldn't be many who think Jiangyin Electrical AlloyLtd's price-to-earnings (or "P/E") ratio of 34.4x is worth a mention when the median P/E in China is similar at about 32x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

For instance, Jiangyin Electrical AlloyLtd's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Jiangyin Electrical AlloyLtd's Growth Trending?

In order to justify its P/E ratio, Jiangyin Electrical AlloyLtd would need to produce growth that's similar to the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 2.8%. As a result, earnings from three years ago have also fallen 13% 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 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's somewhat alarming that Jiangyin Electrical AlloyLtd's P/E sits in line with the majority of other companies. 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 on the share price eventually.

The Final Word

Its shares have lifted substantially and now Jiangyin Electrical AlloyLtd's P/E is also back up to the market median. 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 Jiangyin Electrical AlloyLtd revealed its shrinking earnings over the medium-term aren't impacting its P/E 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 moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
