Suzhou K-Hiragawa Electronic Technology Co., Ltd. (SHSE:603052) shares have continued their recent momentum with a 28% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 83%.

Since its price has surged higher, Suzhou K-Hiragawa Electronic Technology's price-to-earnings (or "P/E") ratio of 69.3x might 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 33x and even P/E's below 20x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

As an illustration, earnings have deteriorated at Suzhou K-Hiragawa Electronic Technology 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.

Is There Enough Growth For Suzhou K-Hiragawa Electronic Technology?

In order to justify its P/E ratio, Suzhou K-Hiragawa Electronic Technology would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 25%. This means it has also seen a slide in earnings over the longer-term as EPS is down 44% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 41% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Suzhou K-Hiragawa Electronic Technology 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 Key Takeaway

Suzhou K-Hiragawa Electronic Technology's P/E is flying high just like its stock has during the last month. 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 Suzhou K-Hiragawa Electronic 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. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
